Cleveland C44607 M42 Cobalt Tool Bit Blank 4 Inches

Product Description

The CLEVELAND C44607 is a rectangle-ground tool bit blank machined from M42 cobalt high-speed steel. It measures 0.25 inches wide, 0.5 inches high, and 4 inches in overall length, making it a standard-size blank ready for custom grinding to a specific cutting profile. M42 cobalt HSS offers superior red hardness and wear resistance compared to standard M2 steel, allowing it to hold an edge at higher cutting temperatures. This blank is supplied ground, meaning all faces are finished to close tolerances, reducing prep time before profile grinding. Machinists and toolroom professionals use these blanks to fabricate single-point turning tools, form tools, and specialty cutters.

This tool bit blank is suited for toolroom and production machining environments where custom cutting geometry is required. It performs in lathe, shaper, and planer applications where the operator grinds the desired relief, rake, and clearance angles to match a specific workpiece material or operation. The M42 grade is particularly well matched to hard-to-machine alloys, stainless steels, and high-temperature materials where standard HSS may break down prematurely.

Key Features

• M42 cobalt high-speed steel construction for elevated red hardness and extended tool life
• Rectangle ground profile on all faces for consistent, close-tolerance starting dimensions
• 0.25 inches wide by 0.5 inches high cross-section in a 4-inch overall length
• 10-degree bevel angle ground in per specification
• Ready for custom profile grinding to lathe, shaper, or form-tool geometry

Compatibility

Designed as a standard-size tool bit blank for use in toolholders and toolrooms requiring a 0.25 inches wide by 0.5 inches high rectangular HSS blank ground to finished dimensions.

Installation Notes

Tool bit blanks are ground to final cutting geometry by a qualified machinist or toolroom technician using a bench or surface grinder equipped with an appropriate wheel. Secure the blank firmly in a toolholder or grinding fixture before profiling to prevent movement. Follow standard grinding safety practices including eye protection and proper wheel guards. Inspect the finished cutting edge for cracks or chips before mounting in a toolholder for cutting operations.
