Cleveland C38932 2-Flute HSS Keyway Tolerance Square Single End Mill

Cleveland C38932 End Mill

The Cleveland C38932 is a square end mill made from high speed steel with a TiN coating. It is intended for general milling operations where a centre-cutting tool is required. Machinists and maintenance technicians use it for slotting and profiling tasks in a range of ferrous and non-ferrous materials. The two-flute design aids chip evacuation in softer workpieces.

Keyway Tolerance Specification

This cutter is ground to a keyway tolerance, meaning its diameter is held to a tighter limit for precise slot fitting. That single dimensional control decides whether the tool will produce a slot that matches a standard key without additional reaming or adjustment. Buyers who need a standard cutting tolerance for roughing or non-critical pockets should select a different end mill.

Sustained Cutting Behaviour

Under continuous load the high speed steel substrate retains hardness at moderate temperatures generated during prolonged cuts. The TiN coating reduces built-up edge and extends tool life compared to uncoated HSS when feed rates are kept consistent. Operators who push aggressive depths of cut without coolant may see accelerated flank wear and loss of dimensional accuracy.
