Seco 02080 Tool Bit Blank WKE45 Cobalt Round

Product Description

The SECO 02080 is a solid cobalt tool bit blank machined to a round end shape, intended for use as raw stock in the fabrication of custom cutting tools, form tools, and special-purpose lathe or mill tooling. Made from WKE45-grade cobalt high-speed steel, this blank measures 6 mm in width, 6 mm in height, and 100 mm in overall length. The WKE45 material grade offers elevated hot hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for grinding into tools that will cut tough or abrasive workpiece materials. Machinists, tool-and-die makers, and production shops use blanks like this when a standard insert geometry does not meet the application requirement.

This blank is appropriate for use in toolroom environments where custom single-point lathe tools, form relieving tools, or specialty threading tools are ground to print. The compact 6 mm cross-section fits small-bore toolholders and Swiss-style lathe applications where reduced shank dimensions are required. The round end profile allows the grinder to establish the desired relief and rake angles from scratch without being constrained by a pre-ground geometry.

Key Features

• WKE45 cobalt high-speed steel construction for improved hot hardness and wear resistance over standard HSS grades
• Round end shape provides a neutral starting profile for custom tool grinding
• 6 mm x 6 mm cross-section suits small-bore holders and Swiss-style lathe setups
• 100 mm overall length offers adequate stock for grinding and resharpening multiple times
• Consistent dimensional tolerance supports accurate tool geometry when ground to specification

Compatibility

Designed as a universal cobalt tool bit blank suitable for use in any toolholder or grinder fixture that accepts a 6 mm square or round-shank blank.

Installation Notes

Tool bit blanks of this type are ground to final geometry by a qualified machinist or tool grinder using a bench or surface grinder equipped with appropriate wheels for high-speed steel. Eye protection, proper wheel guards, and work-rest adjustments per OSHA grinding safety standards apply. The blank should be inspected for surface cracks before grinding. Do not attempt to use an unground blank directly as a cutting tool.
