Seco 63007901 Cobalt Tool Bit Blank 3/8x1/2x3 in WKE45

Product Description

The SECO 63007901 is a solid cobalt tool bit blank ground to a rectangular profile and intended for use in custom tooling applications where the machinist or tool grinder shapes the cutting geometry to suit a specific operation. Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 3/8 inches wide by 1/2 inches high with a 3-inch overall length. WKE45 cobalt HSS delivers elevated red-hardness and wear resistance compared to standard M2 HSS, making it suitable for interrupted cuts, tough alloys, and applications where tool life under heat is a priority.

This blank is used in general metalworking, toolroom, and maintenance machining environments. It is appropriate for lathe work, shaper operations, and any application requiring a custom-ground single-point or form tool. The rectangular cross-section suits standard tool holders and lantern-style post setups common on engine lathes. Machinists and tool grinders working in job shops, production facilities, or maintenance departments will find this blank a practical starting point for specialty tooling needs.

Key Features

• WKE45 cobalt high-speed steel for superior red-hardness and extended tool life
• Rectangular cross-section at 3/8 inches wide by 1/2 inches high for standard toolholder fitment
• 3-inch overall length provides sufficient material for grinding multiple profiles or resharpening
• Unground cutting geometry allows full customization by the end user
• Suitable for machining tough alloys, stainless, and materials prone to work hardening

Compatibility

Designed as a general-purpose tool bit blank for use in standard lathe tool posts, shaper tool heads, and custom toolholder setups accepting 3/8-inch by 1/2-inch rectangular blanks.

Installation Notes

Grinding of this blank should be performed by a qualified machinist or tool grinder using appropriate wheel grades for high-speed steel. Eye protection and a properly dressed grinding wheel are required. Follow shop safety procedures for tool grinding, including adequate wheel guarding and coolant use where applicable. Ensure the finished tool geometry matches the requirements of the intended cutting operation before mounting in the tool holder.
