Seco 63005182 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63005182 is a rectangular cobalt tool bit blank designed for use in custom tooling applications where a precision-ground starting blank is required. Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 0.25 inches wide by 0.5 inches high by 4 inches in overall length. It provides the raw stock machinists and tool grinders need to profile, grind, and finish a cutting tool to a specific geometry. The WKE45 cobalt grade delivers elevated red hardness and wear resistance compared to standard M2 high-speed steel, making it suitable for demanding cutting applications on tough or abrasive workpiece materials.

This tool bit blank is used in machine shops, tool rooms, and production environments where operators grind their own single-point lathe tools, form tools, or special-profile cutters. It is appropriate for use on manual lathes, CNC turning centers, and boring applications where a custom-ground tool geometry is required. The rectangular cross-section is a standard shape compatible with most tool holders and grinding setups used in general metalworking and precision machining operations.

Key Features

• WKE45 cobalt high-speed steel grade provides increased red hardness and wear resistance over standard HSS
• Rectangular cross-section measures 0.25 inches wide by 0.5 inches high for straightforward clamping in standard tool holders
• 4 inches overall length gives sufficient stock for grinding to final tool geometry
• Unground blank format allows full custom profiling by the end user
• Sold individually with a minimum order quantity of one piece

Compatibility

Designed as an OEM-style replacement or shop-stock blank suitable for grinding into single-point lathe tools, boring tools, or form tools compatible with standard tool holders accepting a 0.25 inch by 0.5 inch rectangular shank.

Installation Notes

Grinding of this blank should be performed by a qualified machinist or tool grinder using appropriate wheel grades for cobalt high-speed steel. Secure the blank firmly in a tool grinding fixture or surface grinder vise before beginning any material removal. Use proper eye protection and grinding guards per applicable shop safety standards. Allow the blank to cool adequately during grinding to avoid drawing the temper of the cobalt steel.
