Cleveland C32718 4-Flute Cobalt 8% Square End Mill .25 in 1.75 in LOC 3/8 in Shank

Cleveland C32718 Cobalt End Mill

The Cleveland C32718 is a 4-flute cobalt 8% square end mill designed for general-purpose milling. It features a .25 inch cutting diameter and a 1.75 inch length of cut for material removal. A TiCN coating increases surface hardness and wear resistance during operation. The tool uses a 3/8 inch shank with a Weldon flat for secure holder clamping.

Suited For General Milling Tasks

This cutter suits machinists performing slotting, profiling, or plunging in steel and alloy materials. The center-cut geometry allows axial entry into the workpiece without pre-drilling. Buyers needing coolant-through capability for deep pockets or high-volume chip evacuation should look at alternative tooling. The non-coolant design limits effectiveness in applications requiring directed flood or through-spindle coolant.

Build Integration And Holder Fit

The 3/8 inch shank fits standard Weldon flat holders and collet systems used on manual and CNC mills. An overall length of 3 9/16 inches provides clearance for typical vise setups and fixture heights. The solid cobalt substrate absorbs vibration, reducing chatter on less rigid machines. No neck relief is present, so the full shank diameter extends behind the flutes for maximum holder engagement.
