Seco 63002126 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63002126 is a rectangular cobalt tool bit blank ground to WKE45 material grade specifications. Tool bit blanks serve as the raw stock from which machinists and tool grinders cut, grind, and profile custom cutting tools, form tools, and lathe bits. This blank measures 12 mm wide by 16 mm high with a 200 mm overall length, providing substantial stock for single-point tooling, boring bars, or specialty cutter profiles. The WKE45 cobalt high-speed steel grade offers elevated heat resistance and edge retention compared to standard M2 HSS, making it well suited to interrupted cuts and harder workpiece materials. Machinists and tool-and-die professionals select cobalt blanks when standard HSS does not hold up under demanding cutting conditions.

This blank is used in precision machining environments including job shops, toolrooms, and production machine shops. It is appropriate for manual lathes, mill setups, and surface grinders where the operator profiles the blank to a finished cutting geometry. The rectangular cross-section allows straightforward clamping in standard tool holders and grinding vises. It is a conventional choice for toolroom applications where a custom cutting profile is required and no off-the-shelf insert or indexable tool fits the job.

Key Features

• WKE45 cobalt high-speed steel grade for improved heat and wear resistance over standard HSS
• Rectangular cross-section for stable clamping in tool holders and grinding fixtures
• 12 mm width by 16 mm height profile suits a range of single-point and form tool applications
• 200 mm overall length provides generous stock for multiple regrind cycles or profiling operations
• Supplied as a blank requiring finish grinding to final cutting geometry

Compatibility

Designed as a general-purpose tool bit blank for use in toolrooms and machine shops where operators grind custom cutting tools from raw HSS cobalt stock.

Installation Notes

Grinding and profiling of tool bit blanks should be performed by qualified machinists or tool grinders using appropriate surface or tool-and-cutter grinding equipment. Secure the blank firmly in a grinding vise or magnetic chuck before commencing any grinding operation. Use appropriate personal protective equipment, including eye protection, when grinding high-speed steel. Follow shop safety procedures and applicable OSHA standards for abrasive wheel operations.
