This bit cuts very well, seems to be holding up, I've had about 2 hours of cutting and it's still sharp. Typical use is with a 1/4 EM triangular nut as I had some mechanical play (sometimes hardwood vs fiber) with this bit. -MAX. Fit Depth: 0.18" (0.2" will work, but I scaled it down a bit for security and durability reasons). ) - Pitch: 40% - Feed: 75 ipm
