Seco 63005198 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63005198 is a rectangular cobalt tool bit blank ground to precise dimensions for use as a lathe or grinder starting blank. Measuring 3/8 inches wide by 1/2 inches high with a 4-inch overall length, this blank is manufactured from WKE45-grade cobalt high-speed steel. WKE45 cobalt HSS offers elevated heat resistance and edge toughness compared to standard M2 HSS, making it well suited for interrupted cuts and tougher workpiece materials. Machinists grind this blank to a custom cutting geometry before use. It ships as a single piece and is sold individually.

This tool bit blank is used in machine shops, toolrooms, and maintenance environments where custom-ground single-point turning tools, boring tools, threading tools, or form tools are required. It fits standard lathe tool holders sized for 3/8-inch by 1/2-inch shank stock. Typical applications include custom profile grinding on a bench or surface grinder before mounting in a tool post or boring bar setup. It is appropriate for both production and job-shop environments.

Compatibility

Designed as a standard-dimension tool bit blank for use in lathe tool holders and boring bar setups that accept 3/8-inch by 1/2-inch HSS blank stock.

Installation Notes

Tool bit blanks are ground to final geometry by a machinist using a bench grinder or surface grinder before installation in a lathe tool post or holder. Ensure the grinding wheel is rated for high-speed steel and that appropriate eye protection and wheel guards are in place during grinding. Secure the blank firmly in the tool holder and verify tool height relative to the workpiece centerline before taking a cut. Follow your shop safety procedures and any applicable OSHA machining guidelines.
