Questions about this item

What minimum spindle speed rating should my CNC machine have to run this 75 mm long coated carbide end mill?

The cutter is made from tungsten steel with an HRC55 hardness rating and a 75 mm overall length, so the machine spindle must be rigid enough to handle solid carbide tooling at the chosen feed and speed without excessive run-out.

Will the 6 mm shank and 30.5 mm flute length fit inside my existing ER collet holder without bottoming out?

The tool has a 6 mm diameter shank and a 30.5 mm flute length, so any standard 6 mm collet with at least 30.5 mm of usable clamping depth will hold it securely.
