  • Excellent bits for cnc
Size: 1/4"Dia-1"CL Style: COMPRESSION CUT
This bits are awesome, I cut 5 sheets of 4x8 melamine at speed 200 Ipm, .25 depth per pass before I replaced with a new bit.

  • Great bits, busted shipping, missing one
Size: 1/4"Dia-1"CL Style: UP CUT

  • Great bits, I run them hard!
Size: 1/4"Dia-1"CL Style: COMPRESSION CUT
I run these bits hard through plywood. First depth of cut is .3 inches to avoid tarot and it machines through it like a beast. Never had an issue with these bits. Thanks!

  • Clean cuts, long lasting.
Size: 1/4"Dia-1"CL Style: COMPRESSION CUT
These cut cleanly and last about as long as the “premium” brands. Will definitely buy these again.

  • Sharp enough to cut your fingers
Size: 1/4"Dia-1"CL Style: COMPRESSION CUT
Just as good as the more expensive ones. I use on my 4x8 CNC machine. I get about 10 sheets of small parts out of a bit before it starts getting dull

  • Nice and sharp.
Size: 1/4"Dia-1"CL Style: COMPRESSION CUT
Preliminary look only as I need to run these before giving a final review. This pack is cost efficient as you get 5 compression bits for a reasonable price. Each one comes with the typical protective case (which is a necessity, in my opinion). The shafts are polished to a fine degree. The cutting edges spiral up very precisely until they reverse about 1cm from the tip in the typical compression patterm. The blue nanocoating is there to shed heat and preserve blade life, but only a heavy CNC user who goes through a ton of bits is really going to be able to judge that. Cutting edges are consistently sharp and without any flaws. The tips are nice and pointy, quite sharp and well defined. ... show more

  • Excellent compression bits
Size: 1/4"Dia-1-1/4"CL Style: COMPRESSION CUT
These are excellent compression bits. They are nice and sharp and produce clean cuts. The bits hold up great. I couldn't be happier with the performance of these bits. Wouldn't hesitate to get these again.
