Seco 63007895 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63007895 is a solid cobalt tool bit blank intended for use in custom tooling applications where machinists grind their own cutting geometry. Made from WKE45 cobalt high-speed steel, this blank measures 0.25 inches wide by 0.375 inches high with an overall length of 2.5 inches and a rectangular cross-section. WKE45 cobalt grade offers improved hot hardness and wear resistance compared to standard M2 high-speed steel, making it suitable for interrupted cuts, harder workpiece materials, and elevated cutting temperatures. This blank arrives unground, ready for custom shaping on a bench or surface grinder.

Rectangular tool bit blanks of this size are typically used in single-point turning, boring, threading, and parting operations on manual lathes and screw machines. The 0.25 inch by 0.375 inch cross-section fits standard tool post holders commonly found on smaller engine lathes and toolroom machines. Machinists and toolmakers grind these blanks to specific geometries as required by the job, making them a versatile stock item for job shops, maintenance departments, and toolrooms.

Installation Notes

Installation of tool bit blanks is performed by machinists and toolmakers using a bench grinder or surface grinder to form the desired cutting geometry before mounting in a tool post. Power down and lock out the machine before installing or adjusting the tool bit in the holder. Ensure the tool bit is clamped securely with no overhang beyond what the job requires. Follow applicable shop safety practices and machine manufacturer guidelines when grinding and setting tooling.
