The SECO 02012 is a square tool bit blank machined from WKE45 cobalt high-speed steel, designed for use in custom tooling applications where a pre-formed blank is ground to a final cutting geometry by the machinist or toolroom. The blank measures 7/16 inches wide by 7/16 inches high with an overall length of 3.5 inches. WKE45 cobalt steel delivers elevated heat resistance and edge retention compared to standard M2 high-speed steel, making it well suited for interrupted cuts and harder workpiece materials. This blank is sold individually and requires grinding before use as a cutting tool.
Tool bit blanks like the SECO 02012 are used in manual and CNC lathes, boring bars, and custom form tool holders. They are commonly stocked in toolrooms and machine shops to produce single-point turning tools, threading tools, and special-profile cutters ground to application-specific geometry. The square cross-section seats securely in standard tool holders sized for 7/16-inch tool bits. This product is appropriate for machinists, toolroom technicians, and precision manufacturing professionals working with steel, stainless, cast iron, and other demanding materials.
Designed as a standard tool bit blank for use in tool holders and boring bars that accept 7/16-inch square shank tool bits. Verify holder clearance and shank size before installation.
Grinding of this blank to the required cutting geometry should be performed by a qualified machinist using appropriate bench or tool-and-cutter grinding equipment. Always wear eye protection during grinding operations and ensure the grinding wheel is rated for high-speed steel materials. Secure the finished tool bit firmly in the tool holder before engaging the workpiece, and confirm all machine guards are in place before operation.
