Value Collection 460-10494 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 460-10494 is an unground tool bit blank made from M35 cobalt high-speed steel, ground to a square cross-section and ready for custom sharpening or profiling by the end user. Measuring 5/16 inches wide by 5/16 inches high with an overall length of 2.5 inches, this blank gives machinists a solid starting point for creating single-point turning tools, boring tools, or specialty form tools on a bench grinder or surface grinder. M35 cobalt steel offers improved heat and wear resistance compared to standard M2 high-speed steel, making it well suited for harder workpiece materials and interrupted cuts.

This tool bit blank is intended for use in machine shop environments, tool rooms, and vocational settings where custom tool geometries are required. It fits standard tool post holders and boring bar setups that accept 5/16-inch square shank tooling. Typical users include machinists, tool and die makers, and maintenance technicians who grind their own cutting tools to match a specific profile or replace a worn insert holder with a solid HSS alternative.

Installation Notes

Grinding this blank requires a bench or surface grinder equipped with an appropriate wheel rated for high-speed steel. Secure the blank firmly in a tool holder or vise before grinding to maintain consistent angles. Always wear eye protection and follow shop safety protocols when grinding cobalt steel. Once ground to the desired geometry, seat the tool securely in the tool post and verify clearance angles before engaging the workpiece.
