Seco 02078 Tool Bit Blank Cobalt WKE45 Round 5mm X 100mm

Product Description

The SECO 02078 is a solid cobalt tool bit blank ground to a round end shape and intended for use in custom tooling applications across machining and metalworking operations. Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 5 mm in width, 5 mm in height, and 100 mm in overall length. Tool bit blanks of this type are purchased unground and then precision-ground by the end user or tool grinder to a specific cutting geometry. Licensed machinists, tool and die makers, and CNC tool grinders are the primary installers of this product.

This blank is suited for shops that require custom-profiled cutting tools for turning, threading, form cutting, or other specialized lathe and grinder operations. The cobalt WKE45 material grade offers elevated heat resistance and wear resistance compared to standard M2 high-speed steel, making it appropriate for harder workpiece materials and higher cutting speeds. It is sold individually and is compatible with standard tool holders and grinder setups that accept 5 mm square shank blanks.

Key Features

• WKE45 cobalt high-speed steel construction for improved heat and wear resistance
• Round end shape provides a starting profile for custom tool grinding
• 5 mm x 5 mm cross-section fits standard small-shank tool holders
• 100 mm overall length provides sufficient stock for grinding multiple tool profiles over the blank's service life
• Sold as a single-piece unit with no minimum order beyond one piece

Compatibility

Designed as an OEM-style replacement or aftermarket blank for use in standard tool grinding and custom cutting tool fabrication applications requiring a 5 mm square cobalt high-speed steel bit blank.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified tool grinder or machinist using appropriate surface or tool and cutter grinding equipment. Secure the blank firmly in the grinder's work-holding fixture before grinding to prevent movement. Eye protection and appropriate guards must be used in accordance with shop safety standards. Do not attempt to use an unground blank as a cutting tool.
