I'm struggling a little bit in finding several carbide inserts for my machines. Application is just general purpose around the shop.
I have been looking the carbide charts up and down, and have a handle on the shapes and angles, but the size and other variables escape me.
Anyway, 1st on the list is my set of import lathe tools - 5/8 shanks. They all use the same inserts which look to be TCMT. Well, not knowing much, I quickly ordered a 10 pack from Amazon - TCMT 21.51 3/32 thick. They looked great in the picture, but they are about half the size I need.
What I have are 4.1mm thick and about 15mm on the side length. The hole is 4.5 mm and countersunk. And there is clearance angle. Are the 32.52 the ones I need? What does the 32.52 and 21.51 signify?
Next I have an EM150-34 3 flute fly cutter for my mill. It looks like they need a pretty good clearance angle and no center hole - so TPG32? TPF32? Searching for TPG shows inserts without a center hole, but my ID sheet says N, R, or F are without hole. G is double sided cylindrical hole. So, what gives? Also, do I need a chip breaker style? The 15mm insert from my lathe tools do fit the fly cutter, but there is clearly no need for the center hole.
Then my small boring bar - SIR 0375 K11. The triangle insert in it now has bulges on the sides. And those sides are only about 8mm long - so smaller than the TCMT 21.51 inserts. Internet says Size 11.
My bigger boring bar S-SCLCR12-3 says inserts CCGX, CCMT. Which should I use?
Anybody help with some recommended inserts for me?
Thanks
