Seco 63007905 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63007905 is a rectangular cobalt tool bit blank manufactured to WKE45 material grade. It measures 0.5 inches wide, 1.5 inches high, and 7 inches in overall length. Tool bit blanks are unground stock used by machinists and tool grinders to produce custom single-point cutting tools, form tools, and lathe tooling. The WKE45 cobalt high-speed steel grade provides increased heat resistance and wear durability compared to standard M2 HSS, making it a practical choice for harder workpiece materials and interrupted cuts. This blank arrives uncoated and unground, ready for custom shaping on a bench or surface grinder.

This tool bit blank is suited for use in metal-cutting applications where a custom ground tool profile is required. It is commonly used in manual lathe operations, screw machine setups, and toolroom environments. Machinists and tool and die makers select cobalt HSS blanks like this one when tooling will be subjected to elevated cutting temperatures or abrasive workpiece materials. The rectangular cross-section is the standard profile for most single-point lathe toolholders and boring bar setups.

Key Features

• WKE45 cobalt high-speed steel grade for improved heat and wear resistance over standard HSS
• Rectangular cross-section for compatibility with standard toolholders and grinder fixtures
• 0.5 inches wide by 1.5 inches high cross-section for rigid tooling applications
• 7 inches overall length provides ample stock for grinding and regrinding
• Unground blank allows machinists to grind exact tool geometry for the application

Compatibility

Designed as a standard rectangular HSS tool bit blank for use in toolrooms and machine shops requiring custom ground single-point or form cutting tools.

Installation Notes

Grinding of tool bit blanks should be performed by qualified machinists or tool grinders using appropriate wheel guards and eye protection. Ensure the bench or surface grinder wheel is rated for high-speed steel before grinding. Coolant should be applied as needed to prevent overheating the blank during grinding, which can degrade the temper of the cobalt steel. Follow all applicable shop safety standards when handling and grinding tool steel.
