Seco 02031 Tool Bit Blank WKE45 Cobalt Square 6mm

Product Description

The SECO 02031 is a solid cobalt tool bit blank designed for use in custom tooling applications where a raw, unground blank is required before final shaping by a toolroom or grinding department. Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 6 mm wide by 6 mm high with an overall length of 200 mm. Its square cross-section and consistent cobalt composition make it well-suited for grinding into single-point turning tools, form tools, and specialty cutting geometries. Machinists and tool and die professionals rely on cobalt blanks like the 02031 when standard indexed tooling cannot meet a specific geometry or application requirement.

This blank is intended for toolroom, job shop, and production environments where custom-ground cutting tools are fabricated in-house. The 6 mm by 6 mm profile fits smaller tool holders and boring bars common in precision Swiss-type turning, watchmaking, and fine-component machining. It is also applicable in educational and training settings where tool grinding is part of the curriculum. WKE45 cobalt steel retains hardness at elevated cutting temperatures, making it a reliable substrate for high-speed steel tools subjected to demanding cutting conditions.

Key Features

• WKE45 cobalt high-speed steel grade for elevated heat resistance and edge retention
• Square cross-section profile for consistent grinding and tool seating
• 6 mm by 6 mm body fits small-format tool holders and precision boring bars
• 200 mm overall length provides material for multiple tool grinds or extended reach applications
• Unground blank condition allows full custom geometry by the end user

Compatibility

Designed as a raw tool bit blank for use in any toolroom or grinding application requiring a 6 mm by 6 mm square cobalt high-speed steel blank.

Installation Notes

Tool bit blanks require grinding to final geometry before use in a cutting application. Grinding should be performed by a qualified toolroom machinist using appropriate bench or surface grinding equipment with a wheel rated for high-speed steel. Eye protection and grinding-rated guards must be in place during all grinding operations. The finished tool must be properly seated and clamped in the tool holder before any machining operation begins.
