Seco 63007902 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63007902 is a solid cobalt tool bit blank ground to a rectangular profile for use in custom tooling applications across machining and metalworking operations. Manufactured from WKE45 cobalt high-speed steel, this blank measures 3/8 inches wide, 5/8 inches high, and 5 inches in overall length. It provides the raw stock machinists and toolmakers need to grind single-point cutting tools, form tools, or other specialized profiles to exact geometry. WKE45 cobalt material offers elevated hot hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for interrupted cuts, tough alloys, and elevated cutting temperatures.

This tool bit blank is used in general machining shops, tool and die operations, and maintenance facilities where custom-ground tooling is required. It is appropriate for use in manual lathes, turret lathes, and toolroom setups where the operator grinds the cutting geometry to match the specific application. The rectangular cross-section is a standard profile compatible with most tool bit holders and lantern-style tool posts sized for 3/8 inch stock.

Key Features

• WKE45 cobalt high-speed steel construction for improved hot hardness and wear resistance
• Rectangular end shape for compatibility with standard tool bit holders and tool posts
• 3/8 inches wide by 5/8 inches high cross-section suits common toolroom holder sizes
• 5 inch overall length provides sufficient material for grinding and regrinding multiple times
• Unground blank format allows custom geometry to be applied by the end user

Compatibility

Designed as a standard tool bit blank for use in toolroom and production environments where 3/8 inch tool bit holders or lantern-style tool posts are in service. Specific equipment compatibility depends on the geometry ground by the user.

Installation Notes

Tool bit blanks are typically ground by a machinist or toolmaker using a bench grinder or surface grinder with appropriate grinding wheels rated for high-speed steel. Secure the blank properly in a grinding fixture or tool bit grinding jig to maintain consistent relief and rake angles. Always use eye protection and ensure the grinding wheel guard is in place before grinding operations. Do not use a damaged or unbalanced grinding wheel when shaping this blank.
