[Metrology] Cutting tool steel

Here's a slick add-on for an angle grinder, per Rick Sparber, a member of this forum. You can probably adapt the design to work with your Makita.

How cool is that? Isn't creativity wonderful? Thank you, John.

If you are talking about cutting the end that starts into the hole, watch out. First, reamers are hardened. Next, most are tapered for the first part of the flutes to get started straight in the work and gradually up to size. Some are parallel in diameter, but have cutters like a drill bit on the very tips of the reamer flutes to open up the hole. If you cut the cutting end of the reamer shorter, you are likely to have big trouble with using it.

I'm looking to shorten the chuck end of the reamer, making it the same length as the drill. That way I'll never have to adjust the table height when drilling and reaming.

Roy has the right idea, Dremel tool with a cut off disk. I have had occasion to cut the shanks off a few reamers several times. The Dremel tool does a fast and neat job. It will leave a small burr on the end, remove it with a grinding wheel or even the Dremel tool .

Great idea on the grinder table. I recently bought three of the HF grinders. First thing i did was disassemble the gear heads and washed out what passed for grease, and replaced with a good quality wheel bearing grease. they ran much quieter/ smoother. Mike

I have several reamers that has the shank shorten just for this reason. I either cut off the shank end with a hacksaw or put it in the lathe and use a cutoff tool to shorten the shank.

That's so funny, for under $6 you can get the table they sell which mounts to the grinder. Probably less than the parts cost.

Are you talking about this one??

 

[woodchucker]

Probably. I think that might have been it.

Wowsers!!! I had no idea they sold something like that. Don't think Rick knew about it, either. It's possible it wasn't yet available when Rick devised his table. Anyway, I'll pass the info on to him.
