Seco 02160 Tool Bit Blank 8mm Cobalt WKE45 Round

Product Description

The SECO 02160 is a solid cobalt tool bit blank designed for use in precision grinding, toolmaking, and custom cutting tool fabrication. Manufactured from WKE45 cobalt high-speed steel, it delivers strong wear resistance and elevated heat tolerance, making it well suited for demanding machining environments. The blank measures 8 mm (approximately 0.315 inches) in both width and height, with an overall length of 200 mm (approximately 7.87 inches), and features a round end shape. It ships as a single unit and is intended for professionals who grind or form custom tooling profiles to specification.

This blank is used primarily in toolroom and production grinding applications where a standardized cobalt substrate is required before final profiling. It is appropriate for machinists, tool and die makers, and precision grinding technicians working in job shops, maintenance departments, or production facilities. The 8 mm square cross-section is a common size for lathe tooling, boring bars, and specialty form tools ground in-house.

Key Features

• WKE45 cobalt high-speed steel for superior heat and wear resistance compared to standard HSS
• Round end shape allows flexible orientation during grinding setup
• 8 mm x 8 mm cross-section suits a wide range of small-to-medium toolholder seats
• 200 mm overall length provides ample stock for multiple grind-downs or regrinding cycles
• Single-piece packaging simplifies procurement for low-volume or prototype work

Compatibility

Designed as a general-purpose cobalt tool bit blank for use in standard toolholder seats and grinding fixtures that accept an 8 mm square cross-section profile.

Installation Notes

Tool bit blanks are ground to final geometry by qualified machinists or tool grinders using appropriate surface or tool and cutter grinding equipment. Secure the blank firmly in the grinding fixture before operation and use coolant where applicable to prevent thermal softening of the cutting edge. Always wear proper eye protection and follow shop safety protocols during grinding operations. No machining or installation into a live machine should occur until the blank has been fully profiled and inspected.
