Hi Jim,

I grind most of my tools from 1/2" blanks, but I do have both a left and a right cutting bit that takes the triangular carbide cutter. Ken Lamb also sells sets of 1/2" cutting bits I think.

Todd,

How often do you use the carbide insert cutting tools and what operations do you find them most useful for? I wasn't aware that you used them, so I'm curious about their usefulness. I had considered purchasing these in the past, but had held back because of the rather sketchy results they produce on the PIMO tool. I'm sure that using them on a lathe would provide different results, but I'm not certain how different they would be.

Thanks,

Jeff

hi jeff and todd

that is what i was(am) going to try and use this typeof tool for. right now i am lacking funds to really spend on a grinder and i suck at grinding my own tools being new to the metal lathe. jeff what kind of profile are you using for cutting your tenons. what kind of carbine insert holder i need i dont know one that is 0 deg or one that is -5 deg.

thanks for all your input to everyone

Jim,

I'm going to chime in here. I am assuming you know little about using a lathe. Are you aware that the tool must be at centerline to get a clean cut?
Carbide lathe tools are nice, but I use both high-speed steel and carbide. You can find carbide tools very ine3xpensively. Here's a link-

They are only about $5.50 You'll want the style A right hand tool. As long as you don't run it into the chuck, it should last a good long while.
Best of Luck,
Brad
