Value Collection 460-11184 M42 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 460-11184 is a square tool bit blank made from M42 cobalt high-speed steel, designed for machinists and toolroom professionals who grind their own cutting tools to custom profiles. At 0.5 inches wide by 0.5 inches high and 8 inches in overall length, this blank provides ample stock for grinding single-point lathe tools, boring bars, form tools, and other shop-specific geometries. M42 cobalt HSS offers higher red hardness and wear resistance than standard M2, making it well suited for interrupted cuts and harder workpiece materials.

This tool bit blank is used in manual and CNC turning applications where off-the-shelf insert tooling is not practical. It is a common choice in tool and die shops, maintenance machining environments, and production facilities that require custom-ground profiles. The square cross-section allows the blank to be oriented and clamped consistently in standard tool holders and surface grinders during the grinding process.

Key Features

• M42 cobalt HSS construction for improved red hardness and wear resistance over standard HSS grades
• Square cross-section at 0.5 inches x 0.5 inches for consistent seating in tool holders
• 8-inch overall length provides generous stock for multiple regrinds or longer tooling setups
• Unground blank allows machinists to grind any custom cutting geometry to specification
• Suitable for turning harder and more abrasive workpiece materials where M2 tooling wears prematurely

Compatibility

Designed as a general-purpose unground tool bit blank compatible with standard square tool bit holders and surface grinder setups requiring a 0.5 inch x 0.5 inch cross-section blank.

Installation Notes

Grinding tool bit blanks should be performed by a qualified machinist using a bench or surface grinder equipped with an appropriate wheel for high-speed steel. Ensure the grinding wheel is rated for HSS material and that coolant or frequent quenching is used to prevent overheating the cutting edge, which can reduce hardness. Secure the blank firmly in a grinding vise or fixture before beginning. Follow all applicable shop safety procedures for abrasive wheel use.
