Seco 02158 Tool Bit Blank WKE45 Cobalt Round 6mm X 160mm

Product Description

The SECO 02158 is a solid cobalt tool bit blank machined to a round end shape and sized for tool room grinding, form tool fabrication, and custom cutting tool production. Manufactured from WKE45 cobalt high-speed steel, this blank measures 6 mm wide by 6 mm high with an overall length of 160 mm. WKE45 grade cobalt HSS delivers elevated hot hardness and wear resistance compared to standard M2 HSS, making it a reliable starting material for tooling that will see interrupted cuts, tough alloys, or elevated cutting temperatures. Machinists and tool grinders reach for cobalt blanks when they need a substrate that holds an edge under demanding conditions.

This blank is suited for use in tool and die shops, general machine shops, and maintenance machining environments. It serves as raw stock for grinding single-point lathe tools, fly cutters, form tools, and special-purpose cutting inserts. The 160 mm overall length provides sufficient material for grinding full-profile tools while retaining enough stock for resharpening over the tool's service life. It is appropriate for both manual surface grinders and CNC tool grinders equipped with appropriate wheel dressing capability.

Key Features

• WKE45 cobalt high-speed steel grade for superior hot hardness and edge retention
• Round end shape ready for custom profile grinding
• 6 mm x 6 mm cross-section suits small-bore and precision tool applications
• 160 mm overall length provides adequate stock for full profile grinding and resharpening
• Solid cobalt construction throughout — no coating or laminate layers to grind through

Compatibility

Designed as a general-purpose cobalt HSS tool bit blank for use wherever a 6 mm x 6 mm round-profile blank in WKE45 grade is specified.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified tool grinder or machinist using a suitable abrasive wheel rated for cobalt HSS. Secure the blank firmly in a tool holder or grinding fixture before wheel contact. Wear appropriate eye protection and follow shop safety protocols for grinding operations. Verify final geometry and edge condition before mounting the finished tool in any machine spindle or tool post.
