Dremel Saw Bit From Commercial Button




remember those commercial buttons you usually get at ellections and have nothing to do with afterwards ?! ever wanted to cut a piece of wood or plastic but didn't have the right dremel bit in stock ?! well, what are you waiting for ? start making them !

during the whole project it is VERY recommended that you wear safety goggles !

this dremel bit is NOT a HSS ( High Speed Steel ) tool - do NOT use this bit at high speeds !

this saw bit is effective on relatively soft materials such as wood, plastic, etc.

use this information at your own risk (there shuoldn't be any if you wear protective gear and use the bit with caution).

Step 1: Materials

the materials needed for making of this project are :

1. dremel
2. mandrel
3. grinding bit
4. grinding stone
5. drill bit ~2mm
6. commercial button
7. safety goggles

Step 2: Getting Started

take the button

notice it's made of 3 parts
1. bottom (attached to the safety pin)
2. top (the part we will be using)
3. top cover (the actual comercial - the printed part)

step 1 :
seperate the top with the cover from the bottom using a flat screw driver, knife or any relatively sharf and flat item

step 2 :
seperate the top from the cover (no tools needed)

step 3 :
RECYCLE the paper or plastic cover and the tin bottom

Step 3: Preparing the Shape

as you probably noticed, the top part is not flat, it has a folded edge. what we want is a flat plate, to make it so thake the drinding bit and grind the edge - all the way.

what you will end up with is a circular 2D plate - like a thin coin.

Step 4: Making Sure

find and mark the middle of the plate and drill a ~2mm hole in that spot.

to make sure the plate is perfectly round and centered - put the plate on a mandrel and attach it to the dremel.

after doing so turn the dremel on and hold the grinding stone at the edge of the plate and apply miner pressure, by doing do we grid the plate so it is perfectly centered and round.

after centering and ruonding you can sharpen the plate by holding the grinding stone with a slight angle.

Step 5: Teeth

to make the teeth of the saw take the grinding bit and just start grinding untill you get the shape of teeth you desire. make sure all teeth are identicle and not too deep - it will weaken them.
you dont have to make the teeth super sharp, remember, the saw itself is rather thin and spinning at 1000s of RPM !

    well.. they don't cost much... just buy one - it's really useful (just remember to buy DREMEL and NOT SKIL - mine's a bit off centered, a lot bigger and less comfortable)

    I have 2 corded Dremels and I just bought a cordless one last night at Walmart for $20. Yay!

    My dremel is my baby, this is a good idea but you could more easily buy a bit for it that will come with another bit attacher thing, and it will be much safer and perfectly round so you don't break it and die

    Any ideas on how to make the teeth as small as the original saws you can get?

    Just a suggestion: Slightly bend each tooth up/down in alternating fashion. (Make sure you have an even number of teeth.) If you look at a real sawblade, you'll see this is the case. Either the teeth have inserts so that they are wider than the body, or they are bent outwards, slightly. The idea is that a saw cuts a channel that is slightly wider than the saw blade, itself. This reduces unproductive friction/heat that could ruin the saw and/or the material being cut.

    I like your dremel bit, but does it work on other materials too? because, when plyxy glass is cut, it splits, like bamboo and it splits deep so please upload an other picture when sawing in wood or pvc plzplz ps sorry for my bad english, i'm not from an english country...

    umm... I didn't really try in on different materials, I don't use it too often - I'll do some experiment for you and post them... I guess if you make it from stronger, less flexible and harder material it would cut through more materials. and hey, I'm not from an English speaking country as well (as you can tell from my avatar) where are you from?

    cool, sorry I didn't post the videos yet, I'm in the Israeli army right now so I don't have a lot of time on my hands and I don't really have a variety of materials just laying around waiting to be destroyed. I hope I'll find some time and materials soon.

    Your idea is pretty clever. Do you know the translation of the Hebrew?
