Seco 02072 Tool Bit Blank Cobalt WKE45 Round 4 Inch Oal

Product Description

The SECO 02072 is a solid cobalt tool bit blank designed for use in custom tool grinding and cutting tool fabrication. Made from WKE45 cobalt material grade, this blank measures 3/8 inches wide, 3/8 inches high, and 4 inches in overall length with a round end shape. Tool bit blanks like this one serve as raw stock for machinists and toolmakers who grind their own lathe tools, boring tools, or specialty cutters to precise geometries. The cobalt composition provides elevated heat resistance and wear characteristics compared to standard high-speed steel, making it suitable for demanding cutting applications in metal removal operations.

This blank is appropriate for machine shops, toolrooms, and industrial maintenance environments where custom tool profiles are required. It is well-suited for applications involving harder workpiece materials where cobalt tooling provides an advantage over conventional high-speed steel. Machinists and tool grinders working with manual or CNC lathes, boring mills, and similar equipment use blanks of this size as starting stock for single-point cutting tools and form tools.

Key Features

• WKE45 cobalt material grade for improved heat and wear resistance
• 3/8 inch square cross-section provides a standard blank size for common toolholder setups
• 4 inch overall length offers sufficient stock for grinding and resharpening
• Round end shape for versatile grinding configurations
• Solid cobalt construction throughout the blank

Compatibility

Designed as a standard-size cobalt tool bit blank suitable for use in toolholders and grinder fixtures that accept 3/8 inch square tool stock.

Installation Notes

Tool bit blanks require grinding to a finished cutting geometry before use in a lathe or machining application. Use appropriate bench or tool grinding equipment with suitable wheels rated for cobalt high-speed steel. Eye protection and proper wheel guards are required during grinding operations. Inspect the blank for cracks or defects before grinding.
