Seco 63001457 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63001457 is a rectangular cobalt tool bit blank designed for use in custom tooling applications where a lathe operator or toolroom machinist needs to grind a specific cutting geometry from raw stock. Made from WKE45-grade cobalt high-speed steel, this blank measures 10 mm (0.394 inches) wide, 16 mm (0.630 inches) high, and 160 mm (6.299 inches) in overall length. The cobalt content in WKE45 provides elevated hot hardness and wear resistance compared to standard M2 HSS, making it well suited for interrupted cuts and harder workpiece materials.

This tool bit blank is used in production and toolroom environments where standard off-the-shelf cutting tools do not meet the required geometry. Machinists grind the blank to a custom profile for turning, boring, threading, or form cutting on manual or CNC lathes. It is appropriate for both light production runs and one-off tooling requirements in job shops, maintenance departments, and metalworking facilities. No specific compatible machine models are stated by the manufacturer for this blank stock item.

Key Features

• WKE45 cobalt high-speed steel for improved hot hardness and wear resistance over standard HSS grades
• Rectangular cross-section allows straightforward clamping in standard tool holders and lantern-style post holders
• 160 mm (6.299 inches) overall length provides ample stock for multiple re-grinds over the tool's service life
• Unground blank form gives the machinist full control over final cutting geometry
• Single-piece packaging with no minimum order restriction beyond one unit

Compatibility

Designed as a raw tool bit blank for grinding to custom cutting geometries; compatible with any standard tool holder or grind fixture that accepts a 10 mm wide by 16 mm high rectangular tool bit.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist using a bench or pedestal grinder equipped with an appropriate abrasive wheel for high-speed steel. Eye protection and a properly dressed grinding wheel are required. Ensure the tool holder setscrew torque and clamping arrangement are appropriate for the finished tool profile before beginning any cutting operation. Follow shop safety procedures and applicable OSHA standards when grinding and handling HSS tooling.
