Cleveland C44520 Tool Bit Blank M2 Hss 1/2in Square 4in

Product Description

The CLEVELAND C44520 is an M2 high speed steel tool bit blank designed for machinists and toolroom professionals who grind their own custom cutting tool profiles. The blank measures 0.5 inches wide by 0.5 inches high with a 4-inch overall length and features a square end shape with a 10-degree bevel angle. The ground finish ensures dimensional accuracy and a consistent surface, reducing the amount of material removal needed before final tool geometry is established. M2 high speed steel provides a solid balance of hardness, toughness, and wear resistance suitable for a wide range of cutting applications.

This tool bit blank is used in metalworking environments where lathe, shaper, or planer tooling must be custom-ground to specific geometries. It is well suited for production toolrooms, maintenance shops, and apprentice training programs that require the flexibility to produce single-point turning tools, parting tools, boring tools, and other profiles on demand. The square cross-section and ground surfaces make it straightforward to fixture in a tool grinder vise or surface grinder magnetic chuck.

Key Features

• M2 high speed steel construction for reliable hardness and toughness across common cutting applications
• Square ground end shape with 10-degree bevel angle for reduced hand-grinding prep time
• 0.5 inch by 0.5 inch cross-section fits standard tool holders and grinder fixtures
• 4-inch overall length provides material for multiple regrinds or one extended tool profile
• Ground finish on all surfaces for dimensional consistency and easy layout marking

Compatibility

Designed as a general-purpose tool bit blank for use in standard 0.5-inch square tool holders and tool post setups on metalworking lathes, shapers, and planers requiring custom-ground single-point or form tooling.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or toolroom technician using a bench grinder, tool and cutter grinder, or surface grinder. Ensure the grinding wheel is rated for high speed steel and that proper eye protection and wheel guards are in place before grinding. Secure the blank firmly in the grinder vise or magnetic chuck to prevent movement during material removal. Allow the blank to cool adequately between grinding passes to avoid drawing the temper of the steel.
