Value Collection 460-0111 M35 Cobalt Tool Bit Blank 1/2x4 in

Product Description

The VALUE COLLECTION 460-0111 is a square tool bit blank ground from M35 cobalt high-speed steel. It measures 1/2 inch wide by 1/2 inch high with a 4-inch overall length, providing a solid, unformed blank that machinists and tool grinders shape into custom lathe, boring, or turning tools. M35 cobalt alloy delivers elevated red hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for interrupted cuts and harder workpiece materials. The square cross-section allows grinding on all four sides to create virtually any cutting geometry. Weighing 0.31 pounds, it is a compact blank ready for immediate bench or surface-grinder work.

This tool bit blank is used in machine shops, toolrooms, and maintenance departments where custom or specialty cutting tools are required. It suits applications involving manual lathes, turret lathes, and boring operations where off-the-shelf insert tooling is not practical. Machinists, tool grinders, and industrial maintenance technicians are the primary users. The M35 cobalt composition makes it a common choice when cutting stainless steel, high-temperature alloys, or other materials that generate excessive heat at the cutting edge.

Key Features

• M35 cobalt high-speed steel construction for improved heat and wear resistance
• Square cross-section allows grinding on all four faces for versatile geometry options
• 1/2 inch by 1/2 inch cross-section fits standard tool holders and grinder fixtures in that size range
• 4-inch overall length provides material for multiple regrinds over the tool's service life
• Supplied as a blank with no formed cutting edge, giving the user full control over final geometry

Compatibility

Designed as an OEM-style replacement or stock blank for standard 1/2-inch square tool bit holders and grinding fixtures used in general metalworking and toolroom applications.

Installation Notes

Grinding of tool bit blanks should be performed by qualified machinists or tool grinders using appropriate wheel guards and personal protective equipment including eye and face protection. Dress the grinding wheel before use and allow the blank to cool frequently during grinding to prevent softening the cutting edge. Secure the blank firmly in a tool grinder rest or fixture to maintain consistent rake and clearance angles throughout the grinding process.
