The SECO 63002130 is a rectangular cobalt tool bit blank designed for use in custom tooling applications where a pre-ground, uncoated blank is machined or ground to a specific cutting geometry. Manufactured from WKE45 cobalt high-speed steel, this blank measures 10 mm wide by 20 mm high with an overall length of 200 mm. WKE45 is a high-performance cobalt HSS grade that offers superior hot hardness and wear resistance compared to standard M2 HSS, making it well suited for interrupted cuts, tough alloys, and high-temperature machining environments. It is typically used by tool and die shops, machine shops, and skilled machinists who grind their own lathe tools, boring bars, or form tools to exact profiles.
This blank is appropriate for use in manual and CNC lathe toolholders, boring setups, and custom form tool applications across general machining, aerospace, and mold-and-die work. The rectangular cross-section fits standard square-shank toolholders and tool posts that accept 10 mm width tooling. It is sold individually and is intended for shops that require a specific ground profile not available as an off-the-shelf insert or brazed tool.
Designed as an OEM-style replacement or stock blank for use in toolholders and tool posts accepting a 10 mm wide rectangular shank profile. No specific machine or system compatibility was provided in the product data.
Tool bit blanks are ground to final geometry by a qualified machinist or tool grinder using a bench or surface grinder equipped with an appropriate grinding wheel for HSS or cobalt materials. Secure the blank firmly in a grinding fixture or vise before material removal. Eye protection and proper wheel guarding are required during grinding operations. Allow the blank to cool during grinding to prevent thermal softening of the cutting edge.
