Cleveland C44626 M42 Cobalt Tool Bit Blank 6 in Rectangle

Product Description

The CLEVELAND C44626 is a rectangle-ground tool bit blank machined from M42 cobalt high-speed steel. It measures 3/8 inches wide, 1/2 inches high, and 6 inches in overall length. M42 cobalt HSS offers higher red-hardness and wear resistance than standard M2 steel, making it well suited for interrupted cuts, work-hardening alloys, and other demanding machining conditions. This blank comes ground to consistent dimensions, giving machinists a ready-to-grind starting point for custom single-point or form tools. It is sold individually and fits standard tool holders sized for its cross-section.

The C44626 is intended for use in manual lathes, turret lathes, and similar metal-cutting setups where a custom-ground tool geometry is required. Its 6-inch length provides enough stock to grind multiple profiles or to regrind a worn tool several times over its service life. Toolroom machinists, job shops, and maintenance departments working with stainless steel, titanium, or other difficult-to-machine materials will find the M42 cobalt grade particularly effective at sustained cutting temperatures where standard HSS softens.

Key Features

• M42 cobalt high-speed steel for increased red-hardness and wear resistance over M2 HSS
• Rectangle ground finish provides consistent cross-section dimensions for accurate tool grinding
• 3/8 inches wide by 1/2 inches high cross-section fits common tool holders and boring bar setups
• 6-inch overall length gives ample stock for custom geometries and multiple regrinds
• Sold as a single piece with no minimum order beyond one unit

Compatibility

Designed as an OEM-style replacement and general-purpose blank for manual lathes and turret lathes accepting 3/8 inches by 1/2 inches cross-section tool bits.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist using a bench or pedestal grinder fitted with an appropriate wheel for high-speed steel. Always wear eye protection and ensure the tool rest is properly adjusted before grinding. Inspect the finished tool for cracks or burning before mounting it in the tool holder. Secure all tool holder fasteners to the machine manufacturer's recommended clamping specification before initiating a cut.
