Value Collection 461-0135 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0135 is a rectangle-ground tool bit blank manufactured from M35 cobalt high-speed steel. It measures 0.5 inches wide, 1.5 inches high, and 7 inches in overall length, providing ample stock for grinding custom single-point lathe tools, form tools, or specialty cutting profiles. The M35 cobalt grade offers improved heat and wear resistance compared to standard M2 HSS, making it a practical choice for machinists cutting harder alloys, stainless steels, and abrasive materials. This blank arrives ground on all faces, ensuring consistent dimensions and a ready surface for bench grinder or surface grinder shaping.

This tool bit blank is suited for use in manual engine lathes, turret lathes, and toolroom applications where operators grind their own cutting tools to match a specific profile or nose radius. It is commonly used in production shops, toolrooms, and maintenance machining environments where off-the-shelf insert tooling cannot meet a specific form requirement. Machinists and tool and die makers working with cobalt HSS blanks of this size will find it appropriate for medium to heavy interrupted cuts on tougher workpiece materials.

Key Features

• M35 cobalt HSS construction for enhanced heat resistance and edge retention over standard M2 HSS
• Rectangle ground profile provides a consistent, flat starting surface for custom tool grinding
• 0.5 inches wide by 1.5 inches high cross-section suits medium toolholder slots
• 7-inch overall length allows multiple regrinds over the service life of the blank
• Ground finish on all faces reduces setup time at the bench or surface grinder

Compatibility

Designed as a standard rectangle tool bit blank suitable for toolholders and boring bar setups accepting a 0.5-inch by 1.5-inch cross-section bit.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or toolmaker using a bench grinder or surface grinder equipped with an appropriate wheel for high-speed steel. Wear eye protection and use a grinder rest to maintain consistent relief and rake angles during shaping. Quench the blank frequently in water during grinding to prevent overheating, which can draw the temper and reduce hardness. Secure the finished tool in the toolholder to the manufacturer-specified clamping torque before engaging the workpiece.
