Seco 63002118 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63002118 is a rectangular cobalt tool bit blank ground to WKE45 material grade. It measures 6 mm wide, 12 mm high, and 200 mm in overall length. Cobalt high-speed steel blanks like this one are used as raw stock that machinists and tool grinders cut, profile, and sharpen into custom single-point lathe tools, form tools, or special-purpose cutters. The WKE45 grade delivers a balance of hardness and toughness suited for demanding metal-cutting operations. This blank ships unground, allowing the end user to form it to whatever geometry the job requires.

This tool bit blank is suited for job shops, tool rooms, and production environments where custom tooling geometry is required. It is appropriate for use in manual and CNC turning, boring, and form-tool applications on ferrous and non-ferrous workpiece materials. Machinists who need to grind a specific relief angle, rake, or nose radius to match a part print will start with a blank like this one rather than a standard insert or indexable tool.

Key Features

• WKE45 cobalt high-speed steel grade for elevated hardness and wear resistance
• Rectangle cross-section: 6 mm wide by 12 mm high for rigid, low-profile mounting
• 200 mm overall length provides ample stock for multiple regrinds or long-reach applications
• Unground blank allows custom tool geometry to be applied by the end user
• Single-piece packaging — sold individually with no minimum order beyond one unit

Compatibility

Designed as raw tool stock compatible with any tool holder or block that accepts a 6 mm wide by 12 mm high rectangular shank. Verify holder bore and clamping dimensions before use.

Installation Notes

Tool bit blanks are ground and finished by a qualified machinist or tool grinder using a bench grinder or surface grinder equipped with an appropriate wheel for high-speed steel. Secure the blank firmly in a tool holder or grinding fixture before shaping to prevent movement. Inspect the finished cutting edge for cracks or chipping before mounting in a machine. Follow shop safety protocols for eye protection and wheel guards when grinding.
