Seco 02061 Tool Bit Blank WKE45 Cobalt Square

Product Description

The SECO 02061 is a square tool bit blank machined from WKE45-grade cobalt high-speed steel, designed for use in custom tooling applications where a precision ground, unfluted blank is the starting point. Measuring 20 mm wide by 20 mm high with an overall length of 200 mm (approximately 0.787 inches wide, 0.787 inches high, and 7.874 inches long), this blank gives machinists and tool grinders a consistent, ready-to-grind substrate. The WKE45 cobalt grade offers elevated red hardness and wear resistance compared to standard M2 HSS, making it well suited for demanding cutting tool fabrication.

This tool bit blank is used in machine shops, toolrooms, and manufacturing facilities where standard insert tooling is not practical and a custom-ground single-point or form tool is required. It is appropriate for lathe tool grinding, boring bar fabrication, and specialty cutter applications. The square cross-section fits standard tool holders and grinding fixtures designed for 20 mm shank stock.

Key Features

• WKE45 cobalt high-speed steel grade provides superior red hardness and extended tool life versus standard HSS
• Square cross-section for compatibility with standard 20 mm tool holders and V-block grinding setups
• 200 mm overall length offers ample stock for multiple grinds or custom tool lengths
• Unground blank form allows full custom profile grinding to application-specific geometry
• Consistent material grade throughout for predictable heat treatment and grinding response

Compatibility

Designed as an OEM-style replacement and standard toolroom blank for use in any application requiring a 20 mm square cobalt HSS tool bit blank.

Installation Notes

Grinding and shaping of HSS tool bit blanks is typically performed by a machinist or tool grinder using a bench or surface grinder fitted with an appropriate grinding wheel rated for high-speed steel. Always wear appropriate eye protection and follow shop safety protocols when grinding. Secure the blank in a proper grinding fixture or V-block to maintain consistent geometry and angle during the grinding operation. Allow the blank to cool adequately during grinding to prevent overheating and loss of temper in the cobalt steel.
