Seco 63006396 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63006396 is a rectangular cobalt tool bit blank designed for use in custom tooling applications where machinists and tool grinders need a solid, unground starting point. Made from WKE45-grade cobalt high-speed steel, this blank measures 16 mm (0.63 inches) wide by 20 mm (0.79 inches) high with an overall length of 200 mm (7.87 inches). The WKE45 cobalt alloy provides elevated heat resistance and wear performance compared to standard M2 high-speed steel, making it well-suited for demanding cutting and grinding operations. Tool and die makers, machinists, and metalworking shops use these blanks as raw stock for producing custom lathe bits, form tools, and single-point cutting tools ground to specific profiles.

This blank is appropriate for use in machine shops, tool rooms, and production environments where custom-ground tooling is fabricated in-house. The rectangular cross-section allows for straightforward orientation when grinding relief angles, rake faces, and cutting edges. It fits standard tool holders sized for 16 mm by 20 mm shank profiles. Typical applications include turning, facing, boring, and threading operations on lathes where a purpose-ground tool is required for a specific material or geometry not available off the shelf.

Key Features

• WKE45 cobalt high-speed steel grade for elevated hot hardness and wear resistance
• Rectangular cross-section at 16 mm wide by 20 mm high for precise holder fitment
• 200 mm overall length provides ample stock for multiple grinding sessions or longer tool profiles
• Unground blank surface allows full custom geometry to be applied by the end user
• Cobalt alloy composition supports use in harder workpiece materials compared to standard HSS

Compatibility

Designed as a raw tool bit blank for use in standard tool holders and grinding setups that accept a 16 mm by 20 mm rectangular shank. Confirm holder dimensions before installation.

Installation Notes

Grinding of this blank should be performed by a qualified machinist or tool grinder using appropriate wheel grades for cobalt high-speed steel. Secure the blank firmly in a tool and cutter grinder or surface grinder vise before shaping. Always use proper eye protection and follow shop safety protocols when grinding tool steel. Ensure the finished tool geometry matches the requirements of the intended cutting application before mounting in a lathe or machine tool.
