Questions about this item

What shank diameter does the R0.5 x 15 tapered ball nose end mill need for the collet?

The cutter has a 3.175 mm shank, so use a collet or holder that grips that exact diameter.

Which step do users often miss when installing this 38 mm overall length carbide end mill in a CNC spindle?

Tighten the collet nut to the specified torque while the tool is fully seated; skipping the torque check lets the cutter pull out under load.
