Cleveland C44628 M2 Hss Tool Bit Blank 3/8x5/8x4 in

Product Description

The CLEVELAND C44628 is a rectangle-ground tool bit blank machined from M2 high-speed steel. Designed for use in manual and CNC turning, boring, and form-tool applications, this blank gives machinists a starting point to grind a custom cutting profile to their exact requirements. At 3/8 inches wide, 5/8 inches high, and 4 inches in overall length, it fits a range of standard tool post holders and boring bar setups. The M2 grade provides a solid balance of wear resistance and toughness suitable for general-purpose cutting of ferrous and non-ferrous materials. Each blank arrives ground to size, reducing the amount of stock removal needed before final edge preparation.

This tool bit blank is used in job shop and production machine tool environments. It is appropriate for lathe and mill setups where the operator needs to grind a custom profile — including threading, parting, facing, and radius tools. Machinists in tool-and-die, maintenance, and general fabrication shops regularly stock these blanks as raw material for building custom single-point cutters. The rectangular cross-section suits standard tool holders in light- to medium-duty turning applications.

Key Features

• M2 high-speed steel construction for reliable wear resistance and toughness
• Ground finish reduces prep time before final edge grinding
• Rectangle cross-section fits standard tool post and holder slots
• 3/8 inches wide by 5/8 inches high cross-section for light- to medium-duty tooling setups
• 4 inches overall length provides material for multiple regrinds over the tool life

Compatibility

Designed as a general-purpose M2 HSS tool bit blank for use in standard lathe tool post holders and boring setups that accept a 3/8 by 5/8 inch rectangular shank. Verify holder slot dimensions before installation.

Installation Notes

Tool bit blanks are ground to a custom profile by the machinist using a bench or pedestal grinder equipped with an appropriate grinding wheel for high-speed steel. Always wear eye protection and use a tool rest when grinding. Secure the blank firmly in the tool post or holder before commencing a cutting operation, and confirm that all gibs and set screws are tightened. Dispose of grinding swarf and coolant per applicable shop safety procedures.
