Cleveland C44632 M42 Cobalt Tool Bit Blank 5 Inches

Product Description

The CLEVELAND C44632 is a rectangle ground tool bit blank manufactured from M42 cobalt high-speed steel. It measures 3/8 inches wide, 5/8 inches high, and 5 inches in overall length. Designed as a blank, it requires custom grinding to the desired cutting profile before use, making it suitable for machinists and tool-and-die professionals who need to produce specialty tooling in-house. M42 cobalt steel provides high red hardness and wear resistance, supporting demanding cutting applications on tough workpiece materials where standard high-speed steel tooling falls short.

This tool bit blank is used in manual and semi-automated lathe, boring, and turning operations in job shop, production, and maintenance machining environments. Its ground finish ensures dimensional accuracy out of the box, reducing prep time before the final grinding operation. The rectangular cross-section is the standard profile for single-point lathe toolholders, making it compatible with a wide range of toolpost setups common in both light and heavy-duty machining work.

Key Features

• M42 cobalt high-speed steel for superior red hardness and extended tool life in difficult-to-machine materials
• Rectangle ground profile for consistent cross-section dimensions and accurate blank geometry
• 3/8 inches wide by 5/8 inches high cross-section fits standard single-point lathe toolholders
• 5 inches overall length provides sufficient stock for multiple regrinds
• Sold individually, allowing purchase in exact quantities needed

Compatibility

Designed as a general-purpose tool bit blank for use in standard single-point lathe toolholders accepting a 3/8 inches by 5/8 inches rectangular shank profile. Requires grinding to final cutting geometry before installation.

Installation Notes

Tool bit blanks must be finish-ground to the required rake, relief, and clearance angles before mounting in a toolholder. Grinding operations should be performed by a qualified machinist using appropriate wheel types for high-speed steel. Always wear eye protection and use proper grinding guards during the shaping process. Secure the ground bit firmly in the toolpost before initiating any cutting operation.
