Value Collection 460-10904 M35 Cobalt Tool Bit Blank 7/16in

Product Description

The VALUE COLLECTION 460-10904 is a square tool bit blank ground from M35 cobalt high-speed steel, intended for machinists and toolroom professionals who grind custom cutting tools to specific profiles. At 7/16 inches wide by 7/16 inches high with a 3-1/2 inch overall length, this blank provides a solid starting stock for lathe tools, boring bars, and other single-point cutting applications. M35 cobalt steel offers increased hot hardness over standard M2 HSS, making it suitable for tougher workpiece materials including stainless steel, cast iron, and high-nickel alloys. The square cross-section simplifies setup in standard tool holders and grinding fixtures.

This tool bit blank suits general toolroom and production machining environments where off-the-shelf insert tooling is not practical or economical. It is commonly used in engine lathes, turret lathes, and manual boring mills. Machinists and tool-and-die professionals grind the blank to the required relief, rake, and nose geometry using bench or pedestal grinders. The 7/16 inch cross-section fits tool holders designed for that shank size, which is a common dimension in medium-duty manual turning operations.

Key Features

• M35 cobalt high-speed steel construction for elevated hot hardness and wear resistance
• Square cross-section at 7/16 inches x 7/16 inches for straightforward clamping in standard tool holders
• 3-1/2 inch overall length provides adequate stock for multiple regrinds over the tool life
• Unground blank format allows custom geometry to be applied by the end user
• Suited for machining stainless steel, cast iron, and other difficult-to-cut materials

Compatibility

Designed as a standard tool bit blank for use in tool holders and grinding setups accepting a 7/16 inch square shank, typical of medium-duty manual lathe and boring applications.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist using appropriate grinding equipment; always wear eye protection and follow shop safety protocols during grinding. Ensure the tool holder or grinder work rest is properly set before beginning. No power-down of machine tools is required for blank preparation, but the intended lathe or mill must be fully de-energized before any tool is loaded or adjusted in the machine. Follow applicable shop standards and OSHA general industry guidelines for grinding and tooling operations.
