Step 2: The Dremel's Bits

Almost any Dremel you buy will come with several different bits. Each has its own specific use, and each must be used correctly in order for them to last. Here I will explain the bits I own, and their various uses. I wish I knew how to do those nifty bullet type things, but until then:

Cutting Bits:

Fiberglass Cutting Disc - I love these guys, they are the largest cutting bit you can get for a Dremel, and they tend to last for a good while before breaking. Advantages include deeper cuts and they're able to cut stronger material, such as metal and ceramic. Disadvantages are that refill packs are about $10 for five of them.

Standard Cutting Disc - Also decent for metal, most replacement packs come with many for cheap. They break often, and I've been nicked by flying disc-shrapnel before. Used for all-purpose cutting. Use these before your nice fiberglass ones.

Grinding Bits:

Carbide and Standard Grinding Bits - Both essentially the same, the carbide bits are designed more for metal, however the standard ones work well on it too. Use these whenever you have to take down sharp edges on something. The small carbide one is decent for drilling holes through metal, just make sure you center punch it with a nail or something beforehand.

Various Sized Sanding Bits - Almost self explanatory, use these for sanding wood inner corners and edges. Note that these will break very quickly if you attempt to use them on metal. The sanding discs are used primarily for flat surfaces and edges, you could call these disposable, refill kits are cheap and plentiful. More information on how to change and replace these later.

Carbon Steel Brush Bit - I love this one as well. Very useful for cleaning out tools and taking paint off anything. Scrapes away delicately on a lower setting and more vigorously on a higher setting. Can be used in place of a larger wire brush wheel to clean files.

Drilling Bits:

Drill Bit - When I don't want to go out back to my drill press or get the DeWalt, this is a worthy substitute. Whenever drilling into anything, be sure to center punch it with an awl or Leatherman tool.

Brush Bit - Not truly a drilling bit, but still worthy of mention. Can be used for....well for brushing things. Not the most useful attachment, but it's handy to have...sometimes.
<p>were can i buy this set</p>
EBay has some great kits for economical prices
Thank you so much I've always wondered how to use the different ones correctly
<p>thanks for the great information! Is there a dremel bit for wood? Is there a book to explain how and when to use the different bits. I think I got one when I bought my Dremel but I can't find it now/</p>
<p>Yes, There is, But they're pretty bad</p>
<p>i dont have a dremel tool. As its very expensive where i live. So i bought a chinese tool the shop keeper told me it's Just as good and it is. It runs frm 8000 to 35000rpm. 7 speeds. Just like the dremel , an exact copy. Got it for 3700rs(abt US$40). Came with attachments. </p>
<p>Where did you buy it from?</p>
<p>forgot to mention it Came with aa flex shaft also</p>
<p>Thank you very much!<br>Very illuminating for a newcomer like me =)</p>
<p>Great tutorial. Added to my &quot;favorites&quot;. I am using my Dremel with #544EZLock wood cutting tool. I am cutting out damaged wood on my hardwood floors. My Dremel, (just got it), gets soooo hot I can hardly touch it, and it takes a good 45 minutes to cool down. What am I doing wrong. I run it at 15000. Thanks!!!</p>
If the Dremel itself is getting hot, you may be bearing down to hard on the wood and putting excess strain on the motor. Try decreasing pressure, changing your RPMs and if that doesn't work, your dremel may have an internal fault and might require returning.
<p>Thank you for the advice. My daughter is building a copper pipe glockenspiel (http://www.instructables.com/id/Copper-pipe-glockenspiel/) and she needs to tune the pipes. I think a dremel with a metal grinding bit with be the right tool for the job.</p>
<p>We need a massive accessory kit that includes tons of bits as well as the flex shaft and workstation.</p>
<p>The Dremel 4000 got pretty good reviews. Looks like the one to go for<br><br><a href="http://best-gear.org/dremel-4000-650-120-volt-variable-speed-rotary-kit/ " rel="nofollow">http://best-gear.org/dremel-4000-650-120-volt-variable-speed-rotary-kit/ </a><br><br> <br> Anja Wirth</p>
<p>I have a DREMEL 3000 &amp; im useing it to make an electric guitar &amp; im neerly finished too works like a dream but will have to replace the carbon brushes soon &amp; the sanding bands i love the damm thing</p>
I downloaded the bits' chart from the Dremel site, I had it printed in A3 size and plastified. Very useful.<br /> <a href="http://www.dremeleurope.com/media_all/download/accessories-overview.pdf" rel="nofollow">www.dremeleurope.com/media_all/download/accessories-overview.pdf</a>
<p>yup page not found do not even try it</p>
<p>I would like to have a look on the link but....</p><p>Page not found.....</p>
<p>The link is 4 years old, they updated the site since then.

<p>Many Thx, I did not realize that this article is 4 years old because it appear in my fb recently.<br>Anyway, it helps a lot and thx for reply me.</p>
Sorry to sound a bore, but it's essential to wear safety glasses when using the cutting disks in conjunction with the Dremel or similar tool. <strong>When the cutting disks break</strong> (and I can assure you they will), fragments fly everywhere at colossal speed. If one of these hits you in the eye- it's game over. Be safe!<br/>
<p>I can personally attest to the high levels of pain inflicted by flying broken cutting disks. I'm fortunate enough to still have both eyes, but have gotten blisters on my eyelids before from the hot fragments hitting them.</p>
If you read the whole Instruct able you'll see the the last step is about safety , but thanx for pointing that out :) "Safety First"
Im sorry but that just tickles me, "Safety First" but ironically its on the last page
Your comment is a killer , I'm now left speechless :) you're %100 right ,good one
<p>Wish I'd read this before I destroyed a grinding bit by trying to cut with it. Nice Instructable!</p>
<p>the shame with Dremel accessories is no have much instructions about what's the right uses ( what's material with what bit, and soo )</p>
<p>A nice and usefull instructable! Finally someone who can explain to me what the different bits are for!</p>
Which 'sanding block bit' do I put the small sanding sleeves on? I can change out the large sanding sleeves with the sanding block bit, but I cannot figure out what to put the small sanding sleeves on...Please help...
Hi. I am thinking of replacing my Dremel cordless with a corded version, and am currently looking at model 275 02, used, ebay. I am wondering if I can use all the hundreds of bits, etc. we have for the other model on the new model, as well as all the collars. Also, I am looking at model 225 01 flex shaft, and wondering first if you think it's necessary (cannot tell if the 275 02 will fit nicely in my hand) and second if it will fit. My usage would be mostly for polishing jewelry and removing pointy-bits left from cutting a piece off from earrings or pins for repurposing. The only thing so far that I can see me not liking about 275 02 is the on-off switch being at the bottom close to the cord, rather than right at the top for a quick turn off,but then again, sometimes when turned off I seem to easily turn it on when not wanted, so I need some guidance in that area as well. Meanwhile a huge thank you for all the information you have posted, and all the comments have convinced me into using eye protection, which I hadn't previously done thinking my reading glasses were enough!
this was seriously very helpful! thank you!
Thanks for the cool tips. The more I read, the more I learn.
Nicely done! A few comments (and my apologies if any of these were covered in the other 124 comments...)<br> <br> --Safety is indeed first and foremost; placing the eye-protection blub at the end is actually a good idea. People tend to remember best what they've seen/heard <em>last</em>.<br> <br> --The wire brush tends to lose individual wires as it's used--another good reason for eye protection.&nbsp; Use this attachment in a location where the bits of wire won't get embedded in undesired places such as bare feet.<br> <br> --The non-reinforced cutting discs can be strengthened by wicking a few drops of thin CA (super-fast) glue into the disc.&nbsp; Hobby-store CA is generally superior to the stuff sold in most big-box stores.
and also the non reinforced cut off bits expload from time to time(i might just be using it wrong) another reason for eye protection. <br> <br>and they make a weird smell in my workshop when i use them.
thank you for the pictures. I am so tired of reading instructions using words I am not familiar with on how to do things with tools and I have NO idea what they are talking about. <br> <br>a picture is DEFINITELY worth at least 1,000 words.
i have the same dremel i bought when they 1st came on the market.... nothing beats keyless chuck...nope I am wrong...the flex shaft with a keyless chuck is almost as satisfying as sex......ummmm maybe not....hmmm, but it makes the tool that much better to use. talk to your dentist, ask about old dental bits....they are very good dremel bits designed for very high speed, various shapes n sizes.
I had a Dremel for several years.. After i gave up and 'Retired' on me i brought another which never lived for too long... Then i tried a 'Challange' one from ARGOS ( UK catalogue shop) and it is great. Only cost &pound;20.00 and i use it daily. Its never let me down and ALL acessories fit.... GREAT INSTRUCTABLE...
My first dremel I had for ten of so years, lent it to a friemd he left it out in the rain, I cleaned it up and it still ran good. Second dremel 5 years third 2 years.<br>After that it was a dremel every 1/2 year. I switched to a Black and Decker RTX No troubles at all. Upside, I took apart my old Dremels and stuck the shafts into old screwdriver handles, make wonerderful clamps and third hands for holding small parts.
Because so many of the attachments/bits come with those screws, I kept dropping them and losing them. There are a few way down deep in the floor register. After searching Lowe's and Home Depot, as well as Radio Shack and the optical stores, I learned that the #2 screw doesn't fit, that McMaster-Carr doesn't have the right screw, and that Fastenal can't even special order them. They may be available outside the US, but I work for a machine shop, and even they couldn't get any screws that fit. Perhaps we could have built some, but the cost...<br><br>I finally called Dremel, and they very kindly sent me two screws. It took two weeks and they arrived in this bubble envelope that could have held 2,000 screws. Lesson of the day: It's faster and cheaper to buy a new mandrel - it comes with a screw.
The Dremel Europe site has great tips and videos. Important tips on cutting discs: the 409 (not fiberglass reinforced) should be used double, that is 2 discs together. The 456 (fiberglass reinforced) should be used with a a washer on each side. Click on &quot;Training Videos&quot;. http://www.dremeleurope.com/gb/en/download
Thanks for posting these. I just got a wireless dremel, but I was really disappointed with the lack of explanation on how to use any of the attachments, or even the SpeedClic system. I didnt think to look on their website, cheers<br><br>Oh, and great instructable too :)
also if cutting metal, it would be a shame to get sparks in your eyes.<br /> <br /> RL
Even if you've never worn safety glasses before in your entire life wear them with this little gem of a tool. The little wires can and do fly out and can puncture an eye. In fact this goes for any spinning wire tool.
Good advice, not only metal bits but what ever material your manipulating can cause eye damage,&nbsp; 3 dollars at Home depot can save your sight!!<br />
so true....also,if you're wearing a respirator, make sure you are wearing appropriate goggles that FIT with it. the 3m n95-type respirators, for example, fit very well with the inexpensive gardener-type googles( flat front with flexible top/bottom/sides)<br /> the glasses-style eyeshields leave a large gap that beckons crap to your lower lids<br /> I learned this the hard way and as a result, had to spend a lot of time digging fiberglass out of my lower lids. <br /> VERY IMPORTANT:fiberglass is encapsulated and pushed out of the body eventually, but carbon fiber will continually dig&nbsp; through your body, creating scar tissue as it goes.CF Lovers: Effective Eye Protection FTW!save your sight homies!<br /> great Ible, very useful!<br />
I may be doing something wrong but I think something is not right about my dremel... &nbsp; For some reason the cap unscrews completely whenever i try to use it and the bit falls right off.... any suggestions?
there are several size brass collar inserts that go under the cap if the one your using is worn or to big, your bits wont tighten down and the bit will fall out.<br /> &nbsp; Hint: Remember the bit and the brass insert collar must match in thickness.<br /> If you already double checked this, then it could be a stipped&nbsp; cap screw or threaded collar. <br /> I think that just about might cover it.<br />
the screws on those tiny shafts are always coming loose or braking off. I find those tiny sanding discs and polishers frustrating to use. I love the little one piece tools though, sanders in different shapes and grinders those are nice. I dont mind using those up and having to buy new ones. No frustration there. <br />
