Default When You Absolutely Have To Use HSS

As many of you know I'm not a fan of high speed steel tools in today's world--I avoid it as much as I can for practical reasons. However, there are times when nothing else will really work and you have no choice but to grind a tool. I found this video by Adam Booth which shows such a time. Given the space available and the clearances involved I can't think of an insert style tool that would do the job.

I did something like this--on a smaller scale--about 5-6 years ago and, of course, no video or pictures. If I remember correctly it took about 45 minutes to get the tool right--that's one of the downsides to not grinding a lot of HSS--it takes you longer to get it right. Still, even I can do it if need be.

The video is longer but grinding the tool and using it takes up the first 10 minutes or so...

Measure twice and cut once...or...wait, was that the other way around?

I’ve made similar tools for grooving and cutting internal threads etc. HSS or a piece of carbide silver soldered to a mild steel holder both work.

For ‘fussy’ sizes and shapes, I usually go to a surface grinder and grind them there now. Rough it out on a mill or bench grinder, finish the profile on the surface grinder, and done. A sine vise makes it easy to setup the relief and clearance angles.

Being retired I can use HSS and not worry about cost, I quite like using it although of course I use inserts but being on a fixed income the cost of HSS figures high in my choices. I use it threading a lot as I like to thread in reverse away from the chuck.
It's So Easy

On interrupted cuts for sure.

Even on hard stuff, until I get past the worst bits. Just have to resharpen more often and away we go again.
