Seco 02017 Tool Bit Blank 5/8 in Square Cobalt WKE45

Product Description

The SECO 02017 is a square tool bit blank machined from WKE45 cobalt high-speed steel, intended for use by machinists and toolroom professionals who grind custom cutting tools to specific profiles. Measuring 5/8 inches wide by 5/8 inches high with an overall length of 4.5 inches, this blank provides substantial stock for single-point lathe tools, boring bars, fly cutters, and other custom-ground tooling. WKE45 cobalt grade offers elevated hot hardness compared to standard M2 high-speed steel, making it well suited for harder workpiece materials and interrupted cutting conditions where heat resistance is critical.

This tool bit blank is used in machine shops, maintenance facilities, and toolrooms wherever custom-ground single-point tooling is required. It is appropriate for manual and CNC lathes, shapers, and planers. The square cross-section fits standard tool holders and lantern-style tool posts common in general-purpose turning operations. Machinists and tool grinders working with stainless steel, cast iron, or other demanding materials will find the cobalt grade a reliable choice over conventional HSS blanks.

Key Features

• WKE45 cobalt high-speed steel grade for improved hot hardness and wear resistance
• Square cross-section at 5/8 inches by 5/8 inches for compatibility with standard tool holders
• 4.5-inch overall length provides ample stock for grinding multiple profiles
• Unground blank format allows machinists to grind any custom cutting geometry
• Suitable for turning harder and more demanding workpiece materials

Compatibility

Designed as a standard square tool bit blank for use with tool holders and lantern-style tool posts that accept 5/8-inch square shanks on manual and CNC turning equipment.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or tool grinder using a bench grinder or surface grinder with an appropriate wheel. Ensure the grinding wheel is rated for high-speed steel before use. Secure the blank firmly in a tool grinding fixture or vise to maintain consistent relief and rake angles during grinding. Always wear appropriate eye protection and follow shop safety procedures when grinding cutting tools.
