Cleveland C44518 Tool Bit Blank 7/16in Square M2 Hss

Product Description

The CLEVELAND C44518 is a square-ground tool bit blank machined from M2 high speed steel. It measures 7/16 inches wide by 7/16 inches high with an overall length of 3.5 inches. The blank arrives fully ground with a 10-degree bevel angle, giving machinists a ready-to-grind starting point for custom single-point turning, boring, or threading tools. M2 high speed steel offers good toughness and wear resistance at elevated cutting temperatures, making it a reliable choice for general-purpose manual and CNC lathe work. Licensed machinists and toolroom professionals are the primary users of this blank.

This tool bit blank is suited for use in manual engine lathes, turret lathes, and similar machine tool setups found in production shops, job shops, and maintenance facilities. The square cross-section and ground finish allow the user to grind any desired tool geometry directly onto the blank. It is appropriate for cutting steel, cast iron, aluminum, and similar materials at standard lathe cutting speeds. The 3.5-inch length provides adequate stock for initial grinding and subsequent resharpening over the service life of the tool.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist using a bench or pedestal grinder with an appropriate abrasive wheel. Ensure the lathe is powered off and the workpiece is secure before installing any ground tool bit into the tool post. Follow shop safety protocols and applicable OSHA machine guarding requirements when grinding and handling cutting tools. Inspect the finished tool edge under magnification before use to confirm proper geometry and absence of microcracks.
