Value Collection 461-0103 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0103 is a rectangular tool bit blank machined from M35 cobalt high-speed steel, intended for use in custom tooling applications where a pre-ground, ready-to-shape blank is required. Measuring 0.375 inches wide, 0.75 inches high, and 5 inches in overall length, this blank provides machinists and toolmakers with solid starting material for grinding lathe bits, boring tools, and other single-point cutting tools. M35 cobalt content improves red hardness and wear resistance compared to standard M2 high-speed steel, making it a practical choice for harder workpiece materials.

This tool bit blank is suited for use in machine shops, maintenance facilities, and industrial toolrooms. It is typically used by machinists who grind their own cutting tools to custom profiles for lathe, shaper, or planer work. The rectangular cross-section simplifies clamping in standard tool holders and grinding fixtures. Applications include turning, facing, and boring operations on ferrous and non-ferrous metals where a cobalt-grade tool blank offers longer edge retention.

Key Features

• M35 cobalt high-speed steel for improved heat and wear resistance over standard HSS
• Rectangular cross-section for easy clamping in standard tool holders and vises
• 5-inch overall length provides ample stock for grinding multiple tool profiles
• 3/8 inch width and 3/4 inch height suit common toolroom and lathe applications
• Supplied as a blank for custom grinding to any required cutting geometry

Compatibility

Designed as a general-purpose rectangular tool bit blank compatible with standard tool holders and grinding fixtures that accept 3/8 inch by 3/4 inch cross-section stock.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist using a bench or pedestal grinder equipped with an appropriate wheel for high-speed steel. Always wear eye protection and follow applicable shop safety procedures when grinding. Secure the blank firmly in a tool rest or fixture to maintain consistent grinding angles. Inspect the finished cutting edge before mounting in a tool holder or lathe post.
