Seco 02150 Tool Bit Blank 8x8x63mm WKE45 Cobalt Square

Product Description

The SECO 02150 is a square tool bit blank ground from WKE45 cobalt high-speed steel. It measures 0.315 inches wide by 0.315 inches high with an overall length of 2.48 inches. Tool bit blanks are unformed cutting tool stock used by machinists, tool grinders, and toolroom technicians to profile custom single-point lathe tools, form tools, and specialty cutters. The WKE45 cobalt grade offers elevated red hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for interrupted cuts and harder workpiece materials.

This blank is appropriate for toolroom and production machining environments where operators need to grind a specific cutting geometry from raw stock. The square cross-section suits general-purpose single-point turning, boring, and threading tool applications on manual lathes and turret lathes. Machinists working with stainless steels, tool steels, titanium alloys, and other difficult-to-machine materials typically select cobalt-grade blanks for their improved hot hardness and edge retention under high cutting temperatures.

Key Features

• WKE45 cobalt high-speed steel grade for superior red hardness and wear resistance
• Square cross-section for versatile single-point tool grinding
• Uniform ground stock for consistent geometry when profiling custom cutting edges
• Compact 2.48-inch overall length suitable for standard tool holders and grinder setups
• Sold individually, allowing single-piece procurement for toolroom use

Compatibility

Designed as a general-purpose tool bit blank for use in standard square-shank tool holders sized for 8 mm stock on manual lathes and turret lathes requiring WKE45 cobalt high-speed steel blanks.

Installation Notes

Tool bit blanks require grinding to the desired cutting geometry before use. Grinding should be performed by a qualified toolroom machinist using appropriate wheel grades for high-speed steel. Always use eye protection and proper wheel guards when grinding. Confirm tool holder clearance and shank fit before mounting any ground tool in a lathe or turret.
