Cleveland C44576 Cobalt M42 Square Tool Bit

The Cleveland C44576 is a Cobalt M42 square tool bit designed for general machining and lathe work. It suits machinists and maintenance technicians who need a durable blank for custom grinding or direct use in turning operations.

Check holder compatibility and application needs

Verify that your tool holder accepts a 5/16 in square shank and that the 2-1/2 in overall length fits your machine envelope. Confirm the non-bevelled geometry matches the cutting approach you intend to use before ordering.

Replaces worn or lower-grade blanks

This bit upgrades from standard high-speed steel blanks when longer edge life in abrasive or high-heat materials is required. The jump is worth it for shops seeing rapid wear on softer tool bits during repetitive facing or boring cycles.
