The SECO 63005187 is a rectangular cobalt tool bit blank ground to WKE45 grade cobalt steel, intended for use as raw stock that machinists and toolmakers grind into custom single-point cutting tools, form tools, or specialty inserts. Measuring 0.25 inches wide by 1 inch high by 6 inches overall length, this blank provides ample material for profiling to a required geometry. WKE45 cobalt high-speed steel offers elevated heat resistance and edge retention compared to standard M2 HSS, making it well suited for interrupted cuts and tougher workpiece materials.
This tool bit blank is used in manual and CNC turning, boring, and threading setups where a custom-ground tool profile is required. It is also appropriate for use in toolroom environments where technicians fabricate specialty cutters for production fixtures or repair operations. The rectangular cross-section allows consistent referencing when grinding on a surface grinder or tool and cutter grinder.
Designed as a general-purpose cobalt HSS tool bit blank for use in standard tool holders and grinding fixtures accepting a rectangular shank cross-section.
Tool bit blanks are ground to final geometry by a qualified machinist or toolmaker using a bench grinder, surface grinder, or tool and cutter grinder with appropriate wheel dressing. Eye protection and proper wheel guards must be in place during all grinding operations. Ensure the blank is fully seated and clamped in the tool holder before initiating any cutting operation. Follow applicable shop safety standards and machine manufacturer guidelines when mounting and operating ground tool bits.
