Seco 02045 Tool Bit Blank Square WKE45 Cobalt

Product Description

The SECO 02045 is a square tool bit blank machined from WKE45 cobalt high-speed steel, designed for use in custom tooling applications where a ground or reshaped cutting edge is required. The blank measures 12 mm wide by 12 mm high with a 100 mm overall length, providing a solid, consistent cross-section for lathe, mill, or shaper tooling setups. WKE45 cobalt grade offers improved heat and wear resistance compared to standard M2 high-speed steel, making it well suited for harder workpiece materials and interrupted cuts. Machinists and tool-and-die professionals use blanks like this as the starting stock for form tools, threading tools, and other special-purpose cutters.

This tool bit blank is used in metalworking environments where off-the-shelf cutting geometries do not meet the job requirement. Typical applications include manual and CNC lathe tooling, shaper tooling, and custom single-point cutter fabrication. The square profile allows the blank to be mounted in standard tool holders and ground to the desired rake, clearance, and relief angles in a tool and cutter grinder. It is appropriate for job shops, toolrooms, and production environments working with ferrous and non-ferrous metals.

Key Features

• WKE45 cobalt high-speed steel construction for superior heat resistance and edge retention
• Square cross-section at 12 mm wide by 12 mm high for consistent mounting in standard tool holders
• 100 mm overall length provides ample stock for grinding and reshaping
• Unground blank format allows the end user to form any custom cutting geometry
• Sold individually for single-unit procurement flexibility

Compatibility

Designed as a general-purpose tool bit blank for use in standard square-shank tool holders sized for 12 mm tooling, compatible with manual lathes, shapers, and similar machine tool setups that accept this shank size.

Installation Notes

Tool bit blanks require grinding to a finished cutting geometry before use; a bench or tool and cutter grinder with appropriate grinding wheels for high-speed steel is needed. Secure the blank firmly in the tool holder before mounting on the machine and verify clearance angles are correct for the workpiece material. Always wear appropriate eye protection when grinding. Follow the machine manufacturer and applicable shop safety guidelines during setup and operation.
