Value Collection 460-6330 M42 Cobalt Tool Bit Blank 3/8x8in

Product Description

The VALUE COLLECTION 460-6330 is a square tool bit blank ground from M42 cobalt high-speed steel, designed for machinists and toolroom professionals who need to grind custom lathe, shaper, or planer tool profiles from raw stock. Measuring 3/8 inches wide by 3/8 inches high with an 8-inch overall length, this blank provides ample material for grinding a finished cutting geometry to suit specific turning, facing, or threading operations. M42 cobalt HSS offers elevated red hardness and wear resistance compared to standard M2 tool steel, making it well suited for cutting harder workpiece materials and longer production runs.

This tool bit blank is intended for use in manual and CNC lathes, shapers, and similar machine tools where the operator grinds the cutting geometry to application requirements. It fits standard 3/8-inch tool post holders and boring bar setups common in job shops, maintenance departments, and toolroom environments. Machinists, tool grinders, and metalworking tradespeople working with stainless steel, hardened alloys, and difficult-to-machine materials will find the M42 cobalt grade particularly appropriate for their applications.

Key Features

• M42 cobalt high-speed steel construction for increased red hardness and wear resistance
• Square cross-section at 3/8 inches x 3/8 inches fits standard 3/8-inch tool holders
• 8-inch overall length provides substantial material for regrinding and resharpening
• Unground blank format allows full custom geometry to be applied by the end user
• Suitable for turning, facing, boring, and shaper applications on harder workpiece materials

Compatibility

Designed as an OEM-style replacement-style tool bit blank for use in any machine tool or tool post holder accepting a 3/8-inch square shank tool bit.

Installation Notes

Tool bit blanks must be ground to the required rake, relief, and clearance angles before use in a cutting application. Grinding should be performed by a qualified machinist or tool grinder using appropriate wheel grades for high-speed steel. Secure the blank firmly in a tool holder or vise before initiating any grinding or machining operation. Always wear appropriate PPE, including eye protection, when grinding HSS tool stock.
