Hi

I cut Bone to make NZ style fish hooks and other jewellery so cut fresh cow bone - it's pretty hard but not like stone - i carce it with sanding disc's and Carbide Burrs -
But what i want to know is what type of Disc's would be the best to cut this bone (also part number or exact Disc)
I have tried a few cheapy cut off disc's but they wear out quick and break a lot i would prefer a solid disc i can use many times.

Any info appreciated
Thanks Mark

P.S Merry Xmas all

I'd like an answer to this question also.  I used the EZ-lock metal cut-off wheel to cut white bone and buffalo horn for knife handles.  It worked good (except for the dust, ****!).  I thought about the plastic cutting wheels but didn't try one.  The bone I had was pretty soft.  Not even close to as hard as hard woods.

Hi this is a email (see below) I was sent By dremel themselves but i have not had time to try any yet - let me know if anyone tries these types of disc's

Cheers Mark


****o Mark,

Thank you for writing to Dremel.

It is possible that you're using the 409 or 420 cutting wheel. They are thin, hard abrasive designed to provide a very fine cut in metals such as thin metal shelving, when something needs a precise thin cut. But they are very delicate and can break.

The cutting wheel I've used with success for cutting bone is the 426 or EZ456 fiberglass reinforced cutting wheels. They are a little thicker, but they are reinforced with fiberglass, which makes them stronger and while they will wear down with use they should not break.

Another option is the 545 diamond wheel although this is an expensive wheel and it is coated with diamond particles that will also wear.

Cutting any type of material with Dremel products is a process and will take some time. Please remember to use a light touch letting the speed do the work. Too much force may cause the wheel to wear faster.

Hope this provides some guidance. If you have further questions please let us know. You may also call Dremel customer service at 1-800-437-3635



Kind Regards,

Those thin cut off wheels really burn the bone (in my case cow horn).
I tried the 561 cut bit, and so far, it's much better, didn't burn at all.
I also tried the 456 (not the EZ one), it's ok, but not as clean as the 561. The 561 was a big surprise.

Would love to try the diamond one (545), even though, diameter is pretty small...

IMHO the best accessory for cutting bone is coping saw.
Very fast and easy, also will make much less mess than dremel.

Coping saw blades generally have rather coarse teeth, but most coping saws will accept the finer-toothed blades, about 1/4in. wide, which are made for junior hacksaws. They will be faster and perhaps less inclined to chip, and they will negotiate the slight curve of a razor scale very well..
