Seco 02005 Cobalt Tool Bit Blank 5/16 in WKE45 Square

Product Description

The SECO 02005 is a square tool bit blank machined from WKE45-grade cobalt high-speed steel. Measuring 5/16 inches wide by 5/16 inches high with an overall length of 2.5 inches, this blank provides the raw stock machinists and tool grinders need to create custom single-point cutting tools, form tools, and lathe bits. WKE45 cobalt HSS offers elevated red hardness and wear resistance compared to standard M2 HSS, making it a practical choice for interrupted cuts, tough alloys, and applications where tool life under heat is a priority.

This tool bit blank is suited for use in machine shops, tool rooms, and maintenance facilities where operators grind their own tooling profiles to match specific turning, boring, or facing operations. The square cross-section allows the blank to be held securely in standard tool holders and ground on any face to achieve the required rake, relief, and nose geometry. It is appropriate for manual lathes, turret lathes, and similar single-point tooling setups in both production and jobbing environments.

Key Features

• WKE45 cobalt high-speed steel for improved red hardness and extended tool life in demanding cuts
• Square cross-section for consistent seating in standard tool bit holders and grinding fixtures
• 5/16 inches x 5/16 inches cross-section accommodates common small-to-medium lathe tool post sizes
• 2.5 inches overall length provides sufficient stock for multiple grinds over the tool life
• Unground blank format allows custom geometry to be applied by the end user

Compatibility

Designed as a standard square tool bit blank for use in manual lathes, turret lathes, and single-point tooling applications requiring a 5/16-inch tool bit size.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or tool grinder using a bench or pedestal grinder equipped with appropriate grinding wheels for high-speed steel. Eye protection and proper wheel guards must be used during grinding operations. Ensure the tool is seated fully and clamped securely in the tool post or holder before initiating a cut. Allow the tool to cool adequately between heavy grinding passes to avoid thermal damage to the cutting edge.
