Seco 97484 Tool Bit Blank WKE45 Cobalt Square

Product Description

The SECO 97484 is a square tool bit blank ground from WKE45 cobalt high-speed steel. It measures 14 mm (approximately 0.551 inches) in both width and height, with an overall length of 160 mm (approximately 6.299 inches). This blank provides a solid, unground starting point for machinists and tool grinders who need to form custom single-point lathe tools, boring bars, or special-profile cutters. WKE45 cobalt HSS offers elevated heat and wear resistance compared to standard M2 HSS, making it well suited for cutting harder ferrous materials and interrupted cuts where tool edge integrity matters.

This tool bit blank is used in machine shops, toolrooms, and production environments where custom-ground tooling is required. Typical applications include manual and CNC lathes, screw machines, and boring operations where a shop-ground tool profile is preferred over an indexable insert setup. Machinists grind the blank to the required geometry using bench or pedestal grinders equipped with aluminum oxide or CBN wheels appropriate for cobalt HSS stock.

Key Features

• WKE45 cobalt high-speed steel for improved hot hardness and edge retention over standard HSS
• Square cross-section — 14 mm x 14 mm — for consistent tool height setup in standard tool posts
• 160 mm overall length provides sufficient stock for multiple regrinds over the tool life
• Unground blank allows full custom geometry to be applied by the end user
• Suitable for turning harder ferrous alloys and interrupted-cut applications

Compatibility

Designed as a general-purpose tool bit blank for use in standard tool posts and holders accepting 14 mm square shank tooling on manual and CNC lathes.

Installation Notes

Grinding of cobalt HSS blanks should be performed by a qualified machinist or tool grinder using appropriate wheel grades for high-speed steel. Wear eye protection and ensure adequate wheel guards are in place during grinding operations. Secure the blank firmly in a tool grinding fixture or rest to maintain consistent relief and rake angles. Allow the blank to cool during grinding to prevent softening of the cutting edge through heat buildup.
