Seco 02063 Tool Bit Blank Cobalt WKE45 Round 4 Inch

Product Description

The SECO 02063 is a solid cobalt tool bit blank designed for machinists and toolroom technicians who grind their own cutting tools to custom profiles. Manufactured from WKE45 cobalt high-speed steel, this blank delivers elevated hardness and heat resistance compared to standard M2 HSS, making it well suited for interrupted cuts, tough alloys, and applications where edge retention under thermal load is critical. The blank measures 1/8 inch wide by 1/8 inch high with a 4 inch overall length and features a round cross-section end shape, providing a consistent starting geometry for bench grinding or CNC tool-and-cutter grinder operations.

This tool bit blank is used in job shops, toolrooms, and maintenance machining environments where standard insert tooling is not practical or cost-effective. The round profile and compact 1/8 inch cross-section make it a common choice for boring bar blanks, small-diameter form tools, and lathe tooling ground to tight radii. It is sold individually and is appropriate for both production toolrooms and single-operation custom tool fabrication.

Key Features

• WKE45 cobalt HSS material grade provides superior red hardness and wear resistance versus standard HSS
• Round cross-section end shape suits boring bar and form tool applications
• 1/8 inch x 1/8 inch cross-section for small-bore and precision tooling work
• 4 inch overall length gives ample stock for grinding and re-grinding multiple times
• Sold as a single piece with no minimum order beyond one unit

Compatibility

Designed as a general-purpose cobalt HSS tool bit blank for use with standard bench grinders and tool-and-cutter grinders in toolroom and maintenance machining applications. No specific machine model compatibility is stated by the manufacturer for this blank.

Installation Notes

Grinding and shaping of tool bit blanks should be performed by a qualified machinist or toolroom technician using appropriate wheel guards and eye protection. Dress grinding wheels before use and avoid overheating the blank during grinding, as excessive heat can draw the temper from the cobalt steel and reduce edge hardness. Ensure the grinder rest is set securely before contact and follow your shop safety program for abrasive wheel operations.
