Value Collection 360-0090 M2 Hss Tool Bit Blank 7/16 X 3-1/2 in

Product Description

The VALUE COLLECTION 360-0090 is a square-ground tool bit blank made from M2 high speed steel, intended for machinists and tool grinders who need a ready-to-grind blank for custom lathe, boring, or cutting tool profiles. At 7/16 inches wide by 7/16 inches high with a 3.5-inch overall length, this blank provides a solid, consistent cross-section that holds an edge well after grinding. M2 high speed steel offers a reliable balance of hardness, wear resistance, and toughness suitable for general-purpose metal cutting applications. Sold individually, it fits into standard tool holders sized for 7/16-inch shank tooling.

This tool bit blank is suited for use in machine shops, toolrooms, and maintenance environments where custom-ground single-point tools are required. It is appropriate for manual lathes, shaper machines, and other setups that accept square shank tool bits. Machinists typically grind these blanks to specific rake and relief angles to match the workpiece material and cutting operation. The square ground finish on all faces provides a flat, consistent starting surface for precise hand or machine grinding.

Installation Notes

Grinding tool bit blanks to final geometry should be performed by a qualified machinist using appropriate bench or surface grinders with safety guards in place. Secure the blank firmly in a grinding fixture or tool holder before applying the wheel to prevent slipping. Always wear eye protection and follow applicable shop safety standards when grinding high speed steel. Inspect the finished cutting edge for cracks or irregularities before mounting the tool in any machine spindle or tool post.
