Value Collection 461-0150 M35 Cobalt Tool Bit Blank 5/8x1x7in

Product Description

The VALUE COLLECTION 461-0150 is a rectangular tool bit blank ground from M35 cobalt high-speed steel, intended for machinists and toolroom professionals who grind their own single-point cutting tools to custom profiles. M35 cobalt HSS contains approximately 5 percent cobalt, which raises red hardness and wear resistance compared to standard M2 HSS, making this blank a strong choice for interrupted cuts, hard ferrous materials, and applications where heat buildup shortens tool life. The blank arrives unground on the cutting geometry, giving the user full control over rake angles, relief angles, and nose radius. At 0.5 pounds, it is a solid, single-piece billet ready for surface grinder or bench grinder shaping.

This tool bit blank is suited for manual engine lathes, turret lathes, and toolroom machining operations where custom-ground lathe tools are preferred over indexable insert tooling. It is appropriate for job shops, tool and die operations, vocational training programs, and maintenance machinists who require a reliable, resharpable cutting tool. The rectangular cross-section fits standard tool post holders designed for 5/8 inch wide by 1 inch high shank profiles.

Key Features

• M35 cobalt HSS construction for improved red hardness and extended tool life in difficult materials
• Rectangular cross-section fits standard 5/8 x 1 inch tool post holders
• 7 inches overall length provides ample stock for multiple regrinds over the tool life
• Arrives unground, allowing full custom geometry to be applied by the machinist
• Solid billet construction with no welds or laminations

Compatibility

Designed as a standard rectangular HSS tool bit blank for use in tool post holders and fixtures accepting a 5/8 inch wide by 1 inch high shank profile on manual lathes and toolroom machines.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist using a surface grinder or bench grinder equipped with an appropriate aluminum oxide or CBN wheel. Ensure the grinding wheel is rated for HSS and that eye protection and dust controls are in place during grinding operations. The finished tool should be seated securely in the tool post holder and tightened before engaging the workpiece. Follow shop safety protocols and applicable OSHA standards when operating grinding and turning equipment.
