Seco 02052 Tool Bit Blank WKE45 Cobalt Square 14mm

Product Description

The SECO 02052 is a square tool bit blank ground from WKE45 cobalt high-speed steel, intended for machinists and toolroom personnel who need to custom-grind single-point cutting tools or form tools to a specific profile. The blank measures 14 mm (0.551 inches) wide by 14 mm (0.551 inches) high with an overall length of 100 mm (3.937 inches). WKE45 cobalt HSS offers elevated hot hardness and wear resistance compared to standard M2 HSS, making it a practical choice for tough or abrasive workpiece materials where longer tool life between regrinds is required.

This tool bit blank is suited for use in conventional lathes, shapers, planers, and toolroom applications where a custom ground cutting edge is needed. It is appropriate for both job-shop and production environments where standard insert tooling is not practical or where a specific geometry must be hand-ground to match a part profile. Toolmakers, machinists, and maintenance technicians commonly use blanks of this type to fabricate specialty cutters from scratch.

Key Features

• WKE45 cobalt high-speed steel provides superior hot hardness and extended tool life over standard HSS grades
• Square cross-section (14 mm x 14 mm) allows four usable orientations before discard
• 100 mm overall length gives adequate stock for multiple grinds over the tool life
• Uncoated blank format supports custom profiling on a bench or surface grinder
• Consistent material grade throughout for uniform grinding behavior

Compatibility

Designed as a general-purpose tool bit blank suitable for standard tool holders and grinder fixtures that accept 14 mm square shank cutting tools.

Installation Notes

Grinding of HSS tool blanks should be performed by a qualified machinist or toolmaker using a properly dressed aluminum oxide or CBN wheel suited for high-speed steel. Eye protection and appropriate ventilation are required during grinding. Ensure the grinder rest is set correctly and the blank is secured before contact with the wheel to prevent shattering or kickback.
