Cleveland C44536 Tool Bit Blank 1/8 in Square M42 Cobalt

Product Description

The CLEVELAND C44536 is a square-ground tool bit blank machined from M42 high-cobalt steel, intended for use in custom tooling, form tool grinding, and lathe or boring applications where a precision-ground starting blank is required. Measuring 1/8 inch wide by 1/8 inch high with an overall length of 2-1/2 inches, this blank provides the raw stock machinists and tool grinders need to create custom cutting profiles. M42 cobalt offers superior hot hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for cutting harder workpiece materials at elevated temperatures.

This tool bit blank is used in metalworking shops, machine tool rooms, and maintenance departments where technicians grind their own single-point lathe tools, threading tools, form tools, or specialty cutters. The square cross-section and ground finish provide a consistent starting point for precise hand or machine grinding. It is appropriate for use on manual engine lathes, CNC turrets, boring bars, and similar metal-cutting setups requiring a custom-profile HSS or cobalt cutting edge.

Key Features

• M42 cobalt steel construction for superior hot hardness and extended tool life in demanding cuts
• Square ground finish ensures consistent cross-section dimensions for accurate tool grinding
• 1/8 inch by 1/8 inch cross-section suits small-bore and precision tooling applications
• 2-1/2 inch overall length provides adequate shank length for standard tool holders and boring setups
• Single-piece packaging supports individual replacement or small-quantity toolroom stocking

Compatibility

Designed as a standard square tool bit blank suitable for use in tool holders, boring bars, and grinding fixtures accepting 1/8 inch square shank stock.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or tool grinder using a bench or surface grinder equipped with appropriate abrasive wheels rated for high-speed steel and cobalt alloys. Secure the blank firmly in a tool grinding fixture or vise before grinding to maintain accurate relief and rake angles. Eye protection and proper wheel guarding are required during all grinding operations. Inspect the finished tool edge before mounting in any tool holder or turret.
