Seco 02001 Tool Bit Blank 3/16 in Square Cobalt WKE45

Product Description

The SECO 02001 is a solid cobalt tool bit blank intended for use as a lathe or grinding tool holder insert that machinists and toolmakers grind to a custom cutting profile. Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 3/16 inches wide by 3/16 inches high with an overall length of 4 inches. The square cross-section and consistent dimensions allow precise grinding to any desired cutting geometry. It is suited for shops and tool rooms where custom single-point or form tools are required, and it is typically handled by machinists, tool grinders, and manufacturing maintenance personnel.

This tool bit blank is appropriate for use in manual lathes, engine lathes, and toolroom applications where a custom-ground high-speed steel tool is preferred over an indexed carbide insert. The 3/16-inch square shank fits standard small-bore tool holders and lantern-style post holders common in manual turning operations. WKE45 cobalt grade provides added red-hardness and wear resistance compared to standard M2 high-speed steel, making it a practical choice for harder workpiece materials and interrupted cuts.

Key Features

• WKE45 cobalt high-speed steel construction for enhanced red-hardness and wear resistance
• Square cross-section at 3/16 inches wide by 3/16 inches high for consistent stock removal during grinding
• 4-inch overall length provides adequate material for initial grinding and re-sharpening over the tool life
• Unground blank format allows machinists to produce any custom cutting geometry as needed
• Consistent dimensions ensure reliable fit in standard small-bore tool holders

Compatibility

Designed as an OEM-style replacement or stock tool blank for manual lathes and toolroom grinders that accept 3/16-inch square high-speed steel tool bits.

Installation Notes

Grinding of tool bit blanks should be performed by a qualified machinist or tool grinder using appropriate bench or surface grinding equipment. Ensure the grinding wheel is rated for high-speed steel and that proper eye protection and wheel guards are in place per applicable shop safety standards. Secure the blank firmly in a tool grinding fixture to maintain consistent relief and rake angles during shaping. Allow the blank to cool regularly during grinding to prevent overheating and loss of temper in the cobalt steel.
