Seco 63005201 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63005201 is a solid cobalt tool bit blank ground to a rectangular profile and intended for use as lathe tooling stock. Manufactured from WKE45 cobalt high-speed steel, this blank measures 3/8 inches wide by 5/8 inches high with a 6-inch overall length. It ships unground on the cutting end, allowing machinists and tool grinders to profile and sharpen it to the specific geometry required for the job. WKE45 cobalt grade offers elevated heat resistance and wear life compared to standard M2 high-speed steel, making it well suited for interrupted cuts and harder workpiece materials.

This tool bit blank is used in manual lathes, turret lathes, and similar single-point turning applications found in machine shops, maintenance facilities, and toolroom environments. Machinists grind these blanks to custom profiles including turning, boring, threading, cutoff, and form tool geometries. The rectangular cross-section fits standard tool post holders and lantern-style holders that accept 3/8-inch square or rectangular shank tooling.

Key Features

• WKE45 cobalt high-speed steel construction for improved hot hardness and wear resistance
• Rectangular cross-section: 3/8 inches wide by 5/8 inches high
• 6-inch overall length provides sufficient stock for profiling and re-grinding
• Unground cutting end allows custom geometry to be applied by the end user
• Fits standard 3/8-inch tool post holders used on manual lathes

Compatibility

Designed as a universal tool bit blank for manual lathes and turret lathes that accept 3/8-inch rectangular shank tooling in standard tool post or lantern post holders.

Installation Notes

Tool bit blanks require grinding to the desired cutting geometry before use; a bench grinder or surface grinder equipped with an appropriate wheel is typically used for this operation. Machinists should wear eye protection and follow shop safety procedures during grinding. Secure the finished blank firmly in the tool post and confirm proper tool height relative to the workpiece centerline before commencing a cut.
