Seco 63005248 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63005248 is a rectangular tool bit blank ground from WKE45-grade cobalt high-speed steel. It measures 3/4 inches wide, 1 inch high, and 6 inches in overall length, providing machinists and tool grinders with a solid, unground blank ready for custom shaping. WKE45 cobalt HSS offers elevated heat resistance and wear performance compared to standard M2 HSS, making it well suited for cutting harder workpiece materials at higher surface speeds. This blank is intended to be ground to a finished single-point or form tool profile by a qualified toolroom technician or machinist.

Tool bit blanks of this type are used in manual and CNC turning, boring, threading, and form-tool applications across job shops, production machine shops, and maintenance toolrooms. The rectangular cross-section is the standard starting profile for most lathe tool bit holders and lantern-style post holders. Technicians select blanks at this size for medium to heavy turning applications where a larger cross-section is needed to resist deflection under cut.

Key Features

• WKE45 cobalt high-speed steel grade provides higher hot hardness and wear resistance than standard M2 HSS
• Rectangular cross-section suits standard lathe tool post holders and grinding fixtures
• 6 inches overall length gives adequate material for grinding multiple profiles over the tool life
• 3/4 inches width by 1 inch height cross-section handles medium to heavy turning loads
• Supplied as an unground blank for custom profile grinding to specific tool geometries

Compatibility

Designed as a standard rectangular tool bit blank for use in lathe tool holders, boring bar setups, and toolroom grinding fixtures that accept 3/4 inches by 1 inch cross-section blanks.

Installation Notes

Grinding of tool bit blanks should be performed by a qualified machinist or toolroom technician using appropriate bench or surface grinders with HSS-rated grinding wheels. Eye protection and proper wheel guarding are required during grinding operations. Ensure the grinding wheel is rated for cobalt HSS material before use. Allow the blank to cool adequately during grinding to prevent thermal damage to the cutting edge geometry.
