Cleveland C60490 carbide end mill .375 in diameter 1.5 in length of cut 4 in overall length 3/8 in shank

Cleveland C60490 Carbide End Mill

The Cleveland C60490 is a solid carbide square end mill designed for general-purpose milling operations. Its uncoated substrate suits machinists and fabricators who prefer sharp edges on non-ferrous materials or low-carbon steels. The straight shank fits standard 3/8 inch tool holders without adapters. It serves both manual and CNC milling setups where a versatile .375 inch cutter is required.

Build integration and clearance

The 3/8 inch shank diameter matches common collet and end-mill holder sizes, allowing direct clamping in ER collets or Weldon flats. A 1.5 inch length of cut provides reach for deeper pockets while the 4 inch overall length keeps the tool within standard machine envelope limits. Non-coolant-through design means external flood or mist coolant must be directed at the cutting zone. The straight geometry offers no neck relief, so deep walls require careful step-down planning.

Capacity and headroom

The .375 inch cutting diameter handles slots, profiles and facing cuts in aluminium, brass, plastics and mild steel with appropriate feeds and speeds. Uncoated carbide retains a keen edge in abrasive non-ferrous alloys but wears faster in hardened steels or high-temperature alloys. Maximum depth per pass is limited by the 1.5 inch flute length and machine rigidity rather than the tool itself. Builders needing longer reach, corner radii or coated performance for exotic materials should select a different tool.
