Diamond saw for cutting carbide

[Bob W.]

I recently purchased a few shrink fit tool holders for 1/8" shanks and they only allow about 1/2" of the tool shank to fit into the holder. Most of my tools are 2"+ long so this results in an unacceptable stick out. Does anyone know of a diamond cutter (Dremel?) I could use to shorten these tools quickly and easily?

 

Thanks,

Bob

How about just Wire edm them to length?

Bob, in my experience with them, the shrink fits I've used in the past came with a set screw stop. Something seems wrong. When you use shrink fits repeatedly, a shelf develops in the tool holder and that becomes your permanent stop after awhile. The smaller holders had slits in them that assist with expansion. You should be able to get more than .50 in the holder easily.

These are made by Bilz and I don't see any provisions for a screw stop or similar. I don't have a wire EDM so I guess I'll give the hammer and vise method a try. A little diamond chop saw would be perfect though.

If your going to attempt the hammer and vice method I suggest you score the outside with a diamond wheel so it breaks off fairly clean.. otherwise its most likely gonna look pretty ugly

Those holders will take on the shape of whatever you put in there. The jagged edges on the snapped off emills will possibly just keep shortening the length available to hang on to.

We often back drill our shrinkfit holders to allow longer mould and die style cutters to be shrunk further in without having to shorten them. Just be aware of shrink fits with balancing screws as sometimes you can't drill these due to the depth of the balancing screws.

Bob, we've run into the same problem. Some sort of little ceramic cut off wheel would surely be ideal - but we don't do it often enough to justify any time spent exploring that option. If you have a regular bench grinder with a green wheel, just use the corner of the wheel to cut through the shank. Takes just a few seconds. If you're doing it often, you'll knock the entire corner off the wheel pretty quickly though.

atter boy, like your style

I would contact your local industrial supply company. I am sure they can hook you up with something. We had a little diamond wheel at a company I worked for years ago and it worked great.

we use something like these in our tool grinders if we need to cut off endmills http://www.use-enco.com/1/3/diamond-cut-off-wheel

I think that will work well. I'll go ahead and buy a few.

 

Thanks!

Use a diamond cutoff wheel to score the shank. Then clamp the carbide in a vise and hammer it off with one swing. This may not work as well with larger dia. endmills. After you snap off the shank, you should face and chamfer the end with a diamond wheel or Deckel grinder.

check out ace hardware for dremel wheels they should have them for about $15 I agree with the scribe and break.

Drill clearance in the back of the shrink holder (from the pull stud end obviously) and the long tools slip right in, and she's all peachy.

 

oops, just read back and already suggested, but that's what we do with no problems
