Value Collection 461-0050 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0050 is a rectangle-profile tool bit blank machined from M35 cobalt high-speed steel and supplied in a ground finish. At 5/16 inches wide, 7/16 inches high, and 4 inches overall length, this blank gives machinists and tool grinders a ready-to-shape starting point for custom lathe, shaper, or planer cutting tools. M35 cobalt adds roughly 5 percent cobalt to the standard M2 HSS matrix, raising red hardness and wear resistance for cutting harder workpiece materials. The ground finish ensures consistent dimensional accuracy straight from the package, reducing setup time on the bench grinder or surface grinder.

This tool bit blank suits machine shops, maintenance departments, and vocational training environments that grind their own single-point cutting tools to a specific profile. It is appropriate for use in standard tool bit holders sized for 5/16 inch or compatible rectangular shank tooling. Machinists working with stainless steel, hardened alloys, or other abrasion-resistant materials often select M35 cobalt blanks over standard HSS for improved tool life between regrinds.

Key Features

• M35 cobalt HSS construction for elevated red hardness and wear resistance versus standard M2 HSS
• Ground finish provides dimensional consistency and a flat reference surface for accurate regrinding
• Rectangle cross-section fits standard tool bit holders and is easy to orient in a vise or grinder fixture
• Compact 4 inch overall length suits benchtop and toolroom grinders without excessive overhang
• Single-piece packaging keeps the blank protected until use

Compatibility

Designed as an OEM-style replacement or shop-stock blank for standard rectangular tool bit holders accepting 5/16 inch wide by 7/16 inch high shank profiles commonly found on engine lathes, shapers, and planer machines.

Installation Notes

Tool bit blanks are finish-ground by the machinist to the required cutting geometry using a bench or pedestal grinder; proper eye protection and grinding wheel guards are required during this operation. Secure the blank firmly in a tool grinder vise or fixture to maintain consistent relief and rake angles. Inspect the ground edge under magnification before use, and dress the grinding wheel as needed to prevent loading that can overheat the cobalt steel and reduce hardness.
