Value Collection 460-6300 M42 Cobalt Tool Bit Blank 3/8x6 in

Product Description

The VALUE COLLECTION 460-6300 is a square tool bit blank machined from M42 cobalt high-speed steel, designed for use in custom tooling and lathe work applications. At 3/8 inches wide, 3/8 inches high, and 6 inches in overall length, this blank provides the stock material a machinist needs to grind a custom cutting profile for turning, facing, or threading operations. M42 cobalt steel offers elevated heat and wear resistance compared to standard M2 high-speed steel, making it well suited for cutting harder workpiece materials where tool life is a priority.

This tool bit blank is intended for use in metal cutting and general machining environments. It is commonly used in production shops, tool rooms, and maintenance machining settings where operators need to grind their own single-point cutting tools to a specific geometry. The square cross-section seats consistently in standard tool holders and lantern-style post assemblies found on engine lathes.

Key Features

• M42 cobalt high-speed steel construction for improved heat and wear resistance
• Square cross-section at 3/8 inches x 3/8 inches for consistent tool holder seating
• 6 inches overall length provides ample stock for grinding multiple tool profiles
• Unground blank format allows custom geometry to be applied by the end user
• Compatible with standard lathe tool holders designed for 3/8 inches square blanks

Compatibility

Designed as an OEM-style replacement blank for use in standard tool holders and lantern post assemblies that accept 3/8 inches square tool bits on engine lathes and similar machine tools.

Installation Notes

Grinding of tool bit blanks should be performed by a qualified machinist using an appropriate bench or surface grinder with a suitable grinding wheel rated for high-speed steel. Always wear eye protection and use proper work-holding fixtures when grinding. Ensure the tool holder set screws are fully tightened before engaging the workpiece, and confirm the ground tool geometry matches the intended cutting operation before running the machine.
