Seco 02025 Tool Bit Blank WKE45 Cobalt 1x1x8 Inch

Product Description

The SECO 02025 is a solid cobalt tool bit blank designed for machinists and toolroom professionals who grind or form custom cutting tools to specific profiles. Manufactured from WKE45-grade cobalt high-speed steel, this blank offers excellent red hardness and wear resistance, making it suitable for demanding cutting applications on ferrous and difficult-to-machine materials. The blank measures 1 inch wide by 1 inch high by 8 inches in overall length with a square end shape, providing substantial stock material for grinding lathe bits, boring tools, and other single-point cutting tools to required geometry.

This tool bit blank is intended for use in machine shops, toolrooms, and production environments where standard insert tooling is not practical or where a custom ground profile is required. It is commonly used by machinists, tool and die makers, and maintenance professionals working with manual lathes, shapers, or planers. The square cross-section and full 8-inch length allow multiple tools to be ground from a single blank or accommodate longer reach requirements.

Key Features

• WKE45 cobalt high-speed steel construction provides high red hardness and extended tool life under heat and pressure
• Square end shape allows straightforward grinding to any required cutting geometry
• 1 inch x 1 inch cross-section suits standard heavy-duty lathe and shaper tool holders
• 8-inch overall length provides maximum usable stock for grinding multiple tools or extended-reach applications
• Cobalt alloy composition improves performance over standard M2 HSS when machining harder or abrasive workpiece materials

Compatibility

Designed as an OEM-style replacement or stock blank for use in standard 1-inch square tool bit holders on manual lathes, shapers, and planers requiring a custom-ground cobalt high-speed steel cutting tool.

Installation Notes

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 rated for high-speed steel. Ensure the grinding wheel is properly dressed before use and wear appropriate eye and face protection during all grinding operations. Secure the blank firmly in a tool grinding fixture or vise to maintain consistent relief and rake angles. Allow the blank to cool periodically during grinding to avoid thermal damage to the cutting edge.
