Seco 02077 Tool Bit Blank Cobalt WKE45 Round 4mm

Product Description

The SECO 02077 is a round tool bit blank manufactured from WKE45-grade cobalt high-speed steel. Measuring 4 mm in width, 4 mm in height, and 100 mm in overall length, this blank serves as the raw stock from which custom cutting tools are ground and shaped. Cobalt HSS offers elevated heat resistance and wear hardness compared to standard M2 steel, making it suitable for demanding grinding applications. Machinists and tool grinders use blanks like this to produce form tools, fly cutters, and specialty profile tools to exact specifications.

This tool bit blank is used in tool-and-die shops, machine shops, and maintenance environments where custom or replacement cutting tools need to be ground in-house. The round cross-section and uniform cobalt composition allow consistent grinding from any angle. It is suited for use on surface grinders, tool and cutter grinders, and bench grinders equipped with appropriate CBN or aluminum oxide wheels.

Key Features

• WKE45 cobalt high-speed steel for enhanced heat resistance and edge retention during grinding
• Round cross-section allows 360-degree grinding flexibility for custom tool profiles
• 4 mm x 4 mm cross-section and 100 mm overall length provide stock for a range of small cutting tool forms
• Uniform material composition throughout the blank ensures consistent grindability

Compatibility

Designed as a standard cobalt HSS tool bit blank suitable for use wherever WKE45-grade round tool bit stock is specified for custom cutting tool fabrication.

Installation Notes

Grinding and shaping of tool bit blanks should be performed by a qualified machinist or tool grinder using appropriate grinding equipment and personal protective equipment including eye protection. Ensure grinding wheels are rated for the hardness of cobalt HSS material before use. Secure the blank firmly in a vise or grinding fixture to prevent movement during material removal.
