What do those Dremel bits do? Well I’ll tell ya!

Yeah, I’m an overachiever.

I originally thought I could fit all of my notes from Jill Timm‘s class, The Amazing Dremel, into one blog post.


I did not take into account how many notes I took during the workshop. In fact, my table neighbor at the workshop teased me for two days on how many notes I took.

My plan is to split the information into three blog posts:

Please note that this post only focuses on what the bits look like and what they do. Oh, and the bits mentioned are the only ones that we used in the workshop – we didn’t use any routing bits. Sorry.

That said, let’s talk Dremel bits.

I think that one of the things that both attracted me and freaked me out about the Dremel was its huge buffet of accessories. The packages are labeled by use, but it still seemed like gibberish to me. Jill created the perfect environment for overcoming my Dremel fear.

You can read about my class in the following blog posts:

This post is in no way meant to replace the total awesomeness of taking Jill Timm’s class. I benefited so much from hearing Jill’s experiences and seeing her work in person. If I had bought a Dremel and experimented with it on my own, most likely I would have never tried it on the range of materials that we did in class.

Jill recently announced that she’s taking her Dremel class on the road and would love to be scheduled by your group. I highly recommend the class if you have a chance to attend.

The main categories of bits, according to Dremel, include the following:

  1. Carving & Engraving
  2. Sanding
  3. Cutting
  4. Grinding & Sharpening
  5. Cleaning & Polishing

These categories are pretty consistent among other manufacturers of rotary tool accessories, so you can often find alternatives if you shop around. Carving & Engraving I used two different types of bits that fall into the carving & engraving category – diamond bits and high speed cutters.

Diamond Dremel bits

Diamond Dremel bits

Diamond bits can be used with the following materials:

  • Aluminum
  • Bookboard
  • Ceramic tile
  • Glass
  • Mirror
  • Steel
Dremel high speed cutters

Dremel high speed cutters

High speed cutters can be used with the following materials:

  • Bookboard
  • Linoleum
  • Polymer clay
  • Wood


Sanding involves two different parts – the drum and the sanding band. Sanding bands come in different grits, just like sheets of sandpaper.

To use the sanding band, you simply slide it over the drum. Replace it when it wears out. Easy peasy.

Sanding bits can be used with the following materials:

  • Aluminum
  • Bookboard
  • Plexiglass
  • Polymer clay
  • Wood


There are different types of cutting wheels for different materials.

Dremel cut-off wheels

Abrasive cutting wheels

Abrasive cutting wheels can be used with the following materials:

  • Bookboard
  • Plexiglass
  • Wood
Dremel fiberglass cutting wheel

Fiberglass cutting wheel

Fiberglass cutting wheels can be used with the following materials:

  • Aluminum
  • Bookboard
  • Ceramic tile
  • Wood

To use a cutting wheel, you have to attach it a mandrel.

Unscrew the tiny screw on top of the mandrel and remove one of the washers.

Attaching Dremel cutting wheel

Slide the wheel onto the screw, then add the second washer. Attach the screw to the mandrel base and tighten.

Replace the wheel it when it wears out.

Grinding & Sharpening

Grinding and sharpening stones are made of two basic materials: silicon carbide (green bits) and aluminum oxide (brown, orange, pink, or grey bits). You may have noticed that some of my grinding stones are oddly-shaped. This is because the stones wear out with use. You can reshape your grinding stones using a dressing stone.

Dremel grinding stones

Orange stones

Orange stones can be used with the following materials:

  • Ceramic tile
  • Glass
  • Mirror
  • Steel
Dremel grinding stones

Blue/green  & Pink stones

Blue/green and pink stones can be used with the following materials:

  • Aluminum
  • Ceramic tile
  • Glass
  • Mirror

Cleaning & Polishing

Felt polishing wheels and cones are used in combination with polishing compound.

To use a polishing felt, you have to attach it a mandrel (different from the cutting wheel mandrel). The felt has a tiny hole in the center of it – you screw the mandrel into the hole to attach it.

I can’t decide if I want to hang it in my studio…

In my experience, it is possible to cut (thin) steel as well with the fiberglass cutting wheel. If you’re in a pinch and you have plenty to spare you can also cut (thinner) metals with the abrasive wheels. The most hilarious example I know of was when my dad used a Dremel tool to cut off a part of my brother’s broken braces… he said “I see sparks” and my dad said “I see more!” Anyhow, hopefully I can get my hands on one of those metal cut-off wheels to work on my next few projects instead of buying up fiberglass wheels.

I don’t know if I could have tolerated having a Dremel so close to my face. That must have been fun to watch, though. :)

The fiberglass wheels work real well for steel I’m a welder and I use them all the time, in fact I cut an 8 inch hole I metal siding 30 ga two days age I used 4 to do it but it worked and did a nice job too. Also great for rusty brackets holding mufflers on cars in tight spots.

I like welding as a hobby. The bigger EZ reinforced wheels are very robust. I am fixing to try one on 1/8″ steel.

Hi! I was checking out the link for buying Dremel bits that is out of the UK. I noticed that with each collection of bits, a specific Dremel model number was listed. Are the Dremel bits not universal to all Dremels? I had been thinking all bits could be used on any Dremel. I was actually going to purchase a collection in advance of purchasing a Dremel. I haven’t made up my mind which model I want yet. If they are model specific, I really need to know. I will have to quit procrastinating on my decision of which one to buy :(

By Elissa - 5 May 2014 Reply

Kristi –

I don’t believe that bits/attachments are Dremel-specific. If any of them are, it will likely say something on the package. The different collets included with the Dremel are used to accommodate the assorted bit widths.

I hope that answers your question.

Can I use the pink stones to sharpen knives?

By Elissa - 25 June 2014 Reply

Dawn –

From what I’ve read online, Dremels aren’t recommended for sharpening knives. This is mostly because they run too fast and hot for the work.


By David - 15 August 2014 Reply

You can use the buffing wheels and a cutting rouge. Start by taking a couple passes on a sharpening stone or stick. Then use finer and finer rouges to make it super sharp. Buff out both sides. It will create a small burr which can be removed by buffing the burr side lengthwise or with a couple passes on sharpening stone or stick.

By Stacy C P - 24 June 2014 Reply

AWESOME site!!!!! Thank you, I have a ton of attachments and it’s been a guessing game for far too long.

I have a piece of metal(don’t know what kind) with sharp edges and I want to smooth out the edges so no one gets tetanus(not good). After reading you AWESOME page I think I should use an orange stone, correct? Is there anything you would warn me of in advance?

Thank you again for being so AWESOME!!!!!

By Elissa - 25 June 2014 Reply

Stacy –

You’re so sweet! Thanks for the compliments. :)

I believe that an orange stone would work for your job – unless the metal is harder than the stone, in which case the stone will just wear away. You have nothing to lose by giving it a try. Definitely wear goggles and protective clothing so you don’t get burned by any flying metal bits.

I am trying to figure out this dremel (3000) but it feels like a foreign language. Just trying to match up using visuals. I am hoping to work on a project cutting plastic, using a cutting wheel. However, I cannot find a MANDREL anywhere in this kit. Is this tiny piece imperative and if so, where can I purchase one? Thank you

By Elissa - 27 June 2014 Reply

Bobbie –

You should be able to purchase a mandrel at your local hardware store – it’s a pretty standard attachment. You will definitely need one to be able to use a cutting wheel.

Dremel makes a pedicure kit – you can check out the included attachments and speeds at which it works. That should be a good guide for if and how you can use your Dremel for a pedicure.

LOL PEDICURE AND the sanding wheel works wonders on calluses – carefull not to go too deep too fast , i use mine about every 2 weeks and … it works , never tried trimming my nails …

I use a Dremel for pedicures all the time! Any beauty supply store will have bits to fit a Dremel for both callous and nails! Careful not to sand to long in one spot though or it will burn!

I did a bit of research and found that there are several different attachments you can use to shape and polish stones. I found the following articles on eHow that might be of help:

I’m not sure, but it could be that you’re either not using the right size collet or the one you’re using might not be tight enough. This is just a guess.


By Lewis - 12 September 2014 Reply

I am new to the Dremel world, I have a Multi Pro and a set of aftermarket bits, pads, discs etc. On 2 occasions I accidently switched the MultiPro to the fastest speed and it bent the mandrel to almost a right angle, very dangerous I thought. Is it just cheap aftermarket mandrels or is there another reason?
Thank you and looking forward to some advice.

I want to cut jump rings out of coiled wire? Which tool would I use?

By Elissa - 12 September 2014 Reply

Barb –

It might be better to use a manual wire cutter for making jump rings. I think that the cuts would be easier to control.


By Lisa - 4 October 2014 Reply

Better off with a proper jewellery saw, you’ll get a far cleaner cut than with plier wire cutters, and both sides of your cut will be straight, unlike flush cutters which will only give you one side flat and the other squashed. Get your saw blade through your coil first, then fit the saw blade end into the saw handle and cut all rings at once; ie lengthways along your coil. for more advice please message me

Thanks for the tips!


By Tracy - 25 September 2014 Reply

Just a tip–I use a lot of the sanding disks and they can be expensive and wear out pretty quickly. I bought a 1 inch round scrap booking stamp and cut my own sanding disks out of sheets of sandpaper. It’s a lot cheaper than buying the pre- made disks.

Thanks for the great tip!


By hydranix - 5 October 2014 Reply

Just thought I’d state the obvious.

Not all dremel bits are universal/standard

They’re rated by RPM , and using a higher rated rotary tool than bit can cause catastrophic bit failure which can cause injury if not wearing eye protection.

By Elissa - 5 October 2014 Reply

Thanks for the words of caution. It’s always a good idea to make sure any attachments you purchase are intended for use with your specific Dremel model.


By Sabrina - 5 October 2014 Reply

Wow – Dremel Accessories Guide Poster is amazing!

I love the tip about the sanding discs, however I’d like to do that with the sanding bands to polish polymer clay pieces. The recommended grit goes from 200-1200, which the bands do not come in. Anybody got any suggestions? Anybody done this before? Maybe glue the grit to an worn down band?

Thanks for the website!

Hi Elissa Great article Loads of information Thank You,

I have one question for you ! Would you recommend Router Bits or high speed cutters ? Situation is I have slapped my Dremel 300 Series onto a Pantograph ( Originally Designed For A Router ) for copying designs and sketches onto Russian Birch Plywood on till i get the confidence and skills to try on expensive hard woods ?
I look forward to reading your thoughts on this.

I don’t know for sure, but my gut tells me that you can’t go wrong starting with the high speed cutters.

I’ve been procrastinating using my rotary tool (Canadian Tire house brand) because I didn’t have a clue what to do with it! ( Seems I’m not the only one!)

This was sooo helpful. I have been researching for two days and cant really find info like this on the Dremel website. I have the “sexy” guide poster, printed at home but still having trouble determining which bit to use for what. I can see that engraving bits are probably for engraving just by looking at them but for what materials? This information you provided was just what I was looking for. Wish it was more comprehensive since I plan on using my dremel for everything I think it might be useful for in a woodworking/auto mechanic/household/everydaytool shop. LOL But thanks so much!

Does Dremel or anybody make 1/2 steel bands for an 8220 model, the sanding bands made of sandpaper do not last; I need some to trim my Chihuahuas’ nails at 10.000 RPM, maybe increasing the speed but I have a familial tremor and don’t want to hurt their fragile nails, or myself ( no kidding that’s what I bought the unit for). I am not a hobbyist of anything manual.
Thank you,

I did a quick search and didn’t find any steel bands for the sanding drum attachment. According to this website, you shouldn’t use the grinding stones because they get too hot – I wonder if the same would be true for steel sanding bands. The website offers some great tips – maybe you’ll find it helpful.


By Eric - 15 December 2014 Reply

Thumbs up to your site I’m a moderate dremel user and I found some interesting info for myself throughout the read. Two questions I can’t seem to find any info for on Dremel’s site:
1. Do you know what the different uses are for the grey grinding wheel stone versus the red ones? By grey, I’m referring to the softer, clay-like stone wheels that you have to attatch yourself to a mandel. I assume since it’s a softer stone it’s made for softer shaping but not sure if it’s still intended for metal?

2. I just purchased the Dremel Micro 8050 (5,000rpm to 28,000 rpm), and was curious if you tried this yet and if so, what kind of luck you’ve had at the highest speed setting for cutting. I seem to get a lot of vibration no matter what bit I have inserted. I’m using the Dremel Multi-Chuck for my collet/nut combo, so it can’t be a collet issue.

Thanks! Keep up the good work!

By Elissa - 2 January 2015 Reply

Eric –

In answer to your questions:

1. The softer the grinding stone, the softer the metal you can work on. While a grey stone may not work for shaping metal, it could be used for surface work. This is one of those things that you just have to try out for yourself.

2. I haven’t used that particular model of Dremel, so I can’t offer you any advice there, sorry. :(

Do you have any advice for how to tighten the sanding bands? Mine just rotate around the mandrel and I can’t tighten the screw in the top any more?! Am I doing something wrong?

By Elissa - 2 January 2015 Reply

Vic –

It doesn’t sound like you’re doing anything wrong. I’ve never tried this myself, but maybe you could try to add some bulk to the mandrel by wrapping some slips of paper around it. It would be like shimming – does that make sense? It’s worth a try.

i am wanting to use my new Dremel 200 (Christmas gift – thanks hubby) to sand off the “nubs” on the edges of tile. i buy recycled tiles from the restore it store for craft projects. I think the orange (8193) one is best, but is there something that would work better/faster. i also think i need a mask to wear due to the fine grit – is that correct?

I would give the orange stone a try and see how it works for you. Definitely use a mask when working with tile – safety first!

By Wayne - 10 February 2015 Reply

Vic asked, “Do you have any advice for how to tighten the sanding bands?”

My sanding drum (Dremel #407) has a slightly flexible body. A screw head at one end, when turned in (CW) compresses the rubber drum to grip the interior of the band. Turned CCW, it releases the grip on the drum. This appears to be the way both of the Dremel drums (407 & 430) work. On my #407 drum all my bands have been snug fits even with the tightening screw loosened.

I know I’m late to the party regarding steel cutting, but I think I win! Due to lack of access to a press, I used the “heavy duty cutting disc” wheels to cut the outer bearing races from the spindles/knuckles of my car.

1999 Mercury Cougar, so the race is roughly 1.5cm of hardened steel! Took about 6 discs per race, and I had to cut all the way through on two sides before they would give enough to be chiseled out.

You should mention to people: Use whatever tool works best, even broken bits are useful. I use a 2mm nub of a broken tiny drill bit just like a tiny router blade, You can use it to engrave, widen holes, make corners, etc. I have another micro drill bit that broke but it’s just the right width and length to drill circuit board holes with by hand (full length bits must be perfectly steady or they just snap at that diameter).

By Kevin Schilling - 14 March 2015 Reply

Very helpful since I have a huge box of accessories but don’t know what to use each for. However, one hint, perhaps too obvious, is to put the mandrel in the Dremel tool FIRST, then attach the cutoff wheel with the screw.

You can use a felt polishing point for that kind of task. I would recommend using a light colored polishing compound like Turtle Wax so you don’t stain the glass.
