Value Collection 460-10674 M35 Cobalt Tool Bit Blank 3/8 in Square

Product Description

The VALUE COLLECTION 460-10674 is a square-end tool bit blank made from M35 cobalt high-speed steel, ground to a 3/8-inch wide by 3/8-inch high cross-section with a 3-inch overall length. Cobalt-grade HSS blanks like this are used by machinists, toolmakers, and trade professionals who need to grind custom cutting profiles for lathe turning, boring, and form tool applications. The M35 cobalt alloy provides higher heat resistance and wear resistance than standard M2 HSS, making it well suited for cutting harder workpiece materials. This blank arrives unground, ready for the end user to profile and sharpen to the required geometry.

This tool bit blank is appropriate for manual and CNC lathe toolpost holders that accept 3/8-inch square shanks. It is used in job shops, maintenance machining environments, and metalworking training programs where custom-ground single-point tools are required. Machinists grind these blanks to specific rake, relief, and nose-radius angles based on the workpiece material and operation. The square cross-section seats securely in standard 3/8-inch tool holders without additional shimming.

Key Features

• M35 cobalt high-speed steel construction for improved heat and wear resistance over standard HSS
• 3/8-inch wide by 3/8-inch high square cross-section fits standard 3/8-inch lathe tool holders
• 3-inch overall length provides sufficient stock for grinding and regrinding multiple profiles
• Square end shape — arrives unground for custom profiling by the end user
• Consistent cross-section geometry allows accurate seating in toolpost holders

Compatibility

Designed as a general-purpose blank for use in any lathe toolpost or tool holder accepting a 3/8-inch square shank tool bit.

Installation Notes

Tool bit blanks must be ground to the desired cutting geometry before use; an unground blank is not a finished cutting tool. Grinding should be performed by a qualified machinist using a bench or tool-and-cutter grinder with appropriate wheel dressing and eye protection. Secure the ground bit firmly in the toolpost holder and verify correct height alignment to the workpiece centerline before cutting. Follow the machine manufacturer safety procedures and applicable shop standards when operating lathes or grinding equipment.
