Cleveland C60021 4-Flute Carbide End Mill
This Cleveland C60021 is a square end mill designed for milling operations. It features a carbide construction with four flutes and an uncoated finish. The tool suits machinists and fabricators working with a range of materials.
0.3125 in diameter milling upgrade
The cutter replaces smaller or worn tooling when a 0.3125 in milling diameter is required. Its 0.5 in length of cut and 2 in overall length provide the reach for deeper features. The jump is worth it when the shank diameter must match a 5/16 in holder.
Carbide tool capacity and headroom
The solid carbide body handles general-purpose milling with rigidity and wear resistance. The straight shank and non-coolant-through design fit standard tool holders. It runs out when a coated or coolant-through tool is needed for high-heat or high-volume production.

Questions about this item
What shank diameter does the C60021 end mill need for a tool holder?
The cutter has a 5/16 in shank diameter, so it fits a standard 5/16 in collet or end-mill holder.
How do you install the carbide end mill without damaging the flutes?
Insert the shank fully into the collet, tighten the collet nut to the holder's rated torque, and avoid tapping the cutting edges during seating.
When should the uncoated carbide end mill be replaced?
Replace it when the cutting edges show visible wear, chipping, or when surface finish and dimensional accuracy degrade during milling.
