Seco 02050 Tool Bit Blank WKE45 Cobalt Square

Product Description

The SECO 02050 is a square tool bit blank machined from WKE45 cobalt high-speed steel, intended for grinding into custom single-point or form cutting tools. At 12 mm wide by 12 mm high with a 200 mm overall length, it provides ample stock for machinists and tool-and-die makers to profile the cutting geometry they need. WKE45 cobalt grade delivers elevated hot hardness and wear resistance compared to standard M2 HSS, making it well suited for interrupted cuts and harder workpiece materials. This blank ships unground, ready for custom sharpening on a tool and cutter grinder.

Square tool bit blanks of this size are used in manual lathes, turret lathes, and boring mills where the operator grinds the tool to a specific geometry. They are common in job shops, tool rooms, and maintenance departments that produce specialty form tools, threading tools, or profiling cutters from raw stock. The 12 mm square cross-section fits standard lantern-style and quick-change toolholders sized for that shank dimension. The 200 mm length gives enough material to re-grind the cutting end multiple times before the blank is consumed.

Key Features

• WKE45 cobalt HSS grade for superior hot hardness and extended tool life in demanding cuts

Compatibility

Designed as a raw tool bit blank for use in any toolholder or grinder fixture that accepts a 12 mm square shank; specific equipment compatibility depends on the geometry ground by the end user.

Installation Notes

Grinding this blank to a finished cutting tool requires a tool and cutter grinder fitted with appropriate grinding wheels rated for high-speed steel; always wear eye protection and follow the grinder manufacturer's safe operating procedures. Ensure the workpiece holding fixture is secure before beginning the grind to maintain accurate geometry. When mounting the finished tool in a lathe or mill toolholder, power down the machine and follow the machine tool builder's torquing and clamping instructions.
