Seco 02009 Tool Bit Blank WKE45 Cobalt Square 3/8 in

Product Description

The SECO 02009 is a square tool bit blank machined from WKE45 cobalt steel, intended for use as a lathe tooling blank that machinists and toolmakers grind to a custom cutting profile. The blank measures 3/8 inches wide by 3/8 inches high with an overall length of 3 inches. WKE45 cobalt grade delivers elevated hot hardness and wear resistance compared to standard high-speed steel, making it well suited for interrupted cuts and harder workpiece materials. This blank ships in a ready-to-grind state, requiring no further preparation before custom edge geometry is applied.

Tool bit blanks like the 02009 are used in manual engine lathes, turret lathes, and toolroom machines where the operator grinds a specific relief angle, rake, and nose radius for the job at hand. The 3/8-inch cross-section fits standard tool posts and holders designed for that shank size. Typical users include machinist shops, maintenance departments, and vocational toolrooms performing turning, facing, and boring operations on steel, cast iron, and similar materials.

Key Features

• WKE45 cobalt steel construction provides superior hot hardness and extended tool life over standard HSS blanks
• Square cross-section fits standard 3/8-inch tool posts and holders without modification
• 3-inch overall length provides sufficient material for grinding and re-grinding multiple cutting profiles
• Ships in unground condition, ready for custom profile grinding by the end user
• Consistent dimensions support repeatable fit in lathe tool holders

Compatibility

Designed as a standard 3/8-inch square tool bit blank for use in lathe tool posts and holders that accept 3/8-inch shank tooling.

Installation Notes

Grinding of tool bit blanks should be performed by a qualified machinist using appropriate bench or tool-and-cutter grinders with proper eye and respiratory protection. Secure the blank firmly in a tool holder before mounting in the machine tool, and verify the tool post setscrew is properly torqued before operation. Power down and lock out the lathe before inserting or removing tooling from the tool post.
