Seco 63007907 Tool Bit Blank Cobalt Rectangle WKE45

Product Description

The SECO 63007907 is a cobalt tool bit blank designed for machining applications that require a durable, high-performance cutting tool substrate. Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 5/8 inches wide by 1-1/4 inches high with a 7-inch overall length. The rectangular end shape provides a consistent cross-section suited for grinding and reshaping into custom cutting profiles. Machinists and toolroom professionals use blanks like this when a standard off-the-shelf geometry does not meet the job requirement.

This tool bit blank is used in metalworking operations where a custom-ground tool profile is needed. It is appropriate for lathe tooling, boring, facing, and turning applications across ferrous and non-ferrous materials. The WKE45 cobalt alloy composition provides improved red hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for harder workpiece materials and interrupted cuts at elevated cutting temperatures.

Key Features

• WKE45 cobalt high-speed steel for superior red hardness and wear resistance
• Rectangle end shape provides uniform stock for custom tool grinding
• 5/8 inches wide by 1-1/4 inches high cross-section accommodates a range of tool holders
• 7-inch overall length offers ample material for grinding and resharpening
• Solid cobalt construction supports use on harder workpiece materials and high-heat applications

Compatibility

Designed as a general-purpose cobalt tool bit blank for use in standard rectangular tool holders and grinder setups where a 5/8 inches by 1-1/4 inches cross-section is required.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or toolroom technician using a bench or surface grinder. Appropriate eye protection and grinding wheel guards must be used during shaping operations. Ensure the grinder wheel is rated for the cobalt substrate before beginning. Follow applicable shop safety protocols and OSHA guidelines for abrasive wheel machinery.
