Questions about this item

How do I install the 3.175 mm shank end mill in my CNC collet without runout?

Clean the shank and collet bore, insert the 3.175 mm shank fully, then tighten the collet nut to the machine maker's torque value. The step often missed is verifying runout with a dial indicator before cutting.

When will the HRC55 tungsten carbide coating need replacement?

The coated solid carbide tool lasts until the R0.75 ball nose shows visible wear or chipping. In abrasive materials this can occur after a few hundred metres of cut; inspect the 15 mm flute length regularly and replace when edge quality drops.
