Seco 63005958 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63005958 is a cobalt tool bit blank designed for machining professionals who need a reliable starting material for custom tooling applications. Manufactured from WKE45 cobalt high-speed steel, this blank measures 3/8 inches wide by 3/4 inches high with a 4-inch overall length and a rectangular cross-section. WKE45 cobalt grade offers elevated heat resistance and hardness retention compared to standard M2 high-speed steel, making it well suited for interrupted cuts, harder workpiece materials, and demanding shop environments. Machinists and toolmakers grind these blanks to a finished cutting geometry on a tool and cutter grinder.

This tool bit blank is used in manual lathe, shaper, and planer operations where a shop-ground single-point tool is preferred over an indexable insert system. The rectangular profile accommodates standard tool holders sized for 3/8-inch tooling. Typical applications include turning, facing, boring, and threading operations on a variety of metals. The 4-inch overall length provides sufficient stock for initial grinding and allows for resharpening over the life of the tool.

Key Features

• Rectangular cross-section compatible with standard 3/8-inch tool holders
• 4-inch overall length provides adequate stock for grinding and resharpening
• Uniform blank geometry supports consistent tool angle grinding
• Sold individually — one piece per package

Compatibility

Designed as a general-purpose tool bit blank for use in standard tool holders and grinding setups that accept 3/8-inch width rectangular cobalt blanks.

Installation Notes

Grinding of tool bit blanks is typically performed by a machinist or toolmaker using a bench or pedestal tool and cutter grinder. Always wear appropriate eye protection and use properly dressed grinding wheels rated for high-speed steel. Ensure the workpiece is secure against the tool rest before grinding to maintain accurate geometry. Follow applicable shop safety standards and OSHA guidelines when operating grinding equipment.
