Seco 63001468 Cobalt Tool Bit Blank WKE45 Rectangle

Product Description

The SECO 63001468 is a rectangular cobalt tool bit blank ground from WKE45-grade cobalt high-speed steel. It serves as raw stock for machinists and tool-and-die professionals who grind their own single-point or custom cutting tools to specific profiles. The blank measures 0.394 inches wide by 0.787 inches high with an overall length of 6.299 inches, giving shops a solid starting billet with enough material to grind a finished tool to nearly any angle, relief, or rake geometry required. WKE45 cobalt HSS offers elevated red hardness compared to standard M2 HSS, making it well-suited for interrupted cuts and harder workpiece materials.

This tool bit blank is used in general machining, toolroom, and production environments where standard insert tooling does not cover a required profile. Typical applications include grinding form tools, threading tools, parting tools, and specialty single-point lathe tools. It is appropriate for manual lathes, engine lathes, and small production turning equipment. The rectangular cross-section seats cleanly in standard tool post holders and lantern-style post holders commonly found in toolroom settings.

Key Features

• WKE45 cobalt high-speed steel for improved red hardness and wear resistance over standard HSS grades
• Rectangular cross-section at 0.394 inches wide by 0.787 inches high for stable seating in tool holders
• 6.299 inches overall length provides ample stock for multiple grinding operations or regrinding
• Unground blank format allows full custom geometry — rake, relief, and nose radius determined by the end user
• Single-piece packaging supports individual toolroom purchases without minimum overstock

Compatibility

Designed as a general-purpose cobalt HSS tool bit blank compatible with standard rectangular tool post holders and toolroom grinding setups that accept 0.394 inch by 0.787 inch cross-section stock.

Installation Notes

Grinding tool bit blanks requires a bench or surface grinder equipped with appropriate aluminum oxide or CBN wheels rated for high-speed steel. Eye protection and a wheel guard must be used at all times during grinding. Allow the blank to cool frequently during grinding to prevent loss of temper in the cobalt steel. Finished tools should be inspected for correct geometry and edge condition before mounting in a tool post and engaging a workpiece.
