How many of each QCP tool holders ?

[coyotechet]

My two tools carbide and Hss for cutting the .00001 Tenon shoulder corner. Some times go an extra couple of thousands but find it not really needed with either tool.

It's true that everyone is different, but I have not yet seen anyone in this thread, or any other on the subject, on this board or any other, say "I bought too many toolholders.".

Just an observation.

Truth.

I'm with you on the HSS tool.... now where did you buy that carbide one?

I gotta' ask..... HOW do you guys do it, the one single tool to face and set the tenon/shoulder???

I've got a barrel for a Panda in the lathe right now and that corner at the shoulder has about a 00.00001 relief radius. I'm using a tool looks like a knife blade tip to get in and clean up for a solid seat and I have nothing in carbide that's even CLOSE to a tight enough radius. And the typical surface ground recoil lugs from PTG are also often basically knife-edged at the corners....

That’s where an undercut is used. When you face the shoulder, plunge into the tenon at least one tool nose radius.

You can never have to many for the square tooling shank size you routinely use.

Al all I know is they are a Mitsubishi insert razor sharp and to the point. A tool and die maker friend got them for me few years back. Check the picture below and then check your PM.
