Seco 02083 Round Tool Bit Blank Cobalt WKE45

Product Description

The SECO 02083 is a round tool bit blank machined from cobalt high-speed steel at material grade WKE45. It measures 8 millimeters in diameter, 8 millimeters in height, and 100 millimeters in overall length. Tool bit blanks are unground stock used by toolmakers, machinists, and grinding shops to produce custom single-point cutting tools, boring bars, and lathe bits ground to a specific profile. The cobalt content improves heat resistance and hardness retention compared to standard high-speed steel, making this blank well suited for demanding cutting applications where tool life matters.

This blank is appropriate for use in machine shops, tool and die operations, and production environments where custom-ground tooling is required. It suits applications involving hard or abrasive workpiece materials where a cobalt-grade blank offers a meaningful advantage over M2 or equivalent standard grades. Toolmakers grind these blanks to finished geometry using surface grinders or tool and cutter grinders. Packaging quantity is one piece per unit.

Key Features

• Cobalt high-speed steel construction at WKE45 grade for elevated heat and wear resistance
• Round cross-section, 8 millimeters in diameter and 8 millimeters high, for versatile grinding profiles
• 100 millimeters overall length provides adequate stock for single-point tool grinding
• Supplied as an unground blank, ready for custom profile grinding to application requirements
• Sold individually, allowing procurement of exact quantities needed

Compatibility

Designed as an unground round tool bit blank for use in standard tool holders and grinding fixtures that accept 8-millimeter round shank stock.

Installation Notes

Grinding of tool bit blanks should be performed by qualified toolmakers using appropriate surface or tool and cutter grinding equipment with suitable wheel grades for cobalt high-speed steel. Secure the blank firmly in a grinding fixture or vise before beginning any grinding operation. Eye protection and proper dust collection are required when grinding cobalt-grade materials. Handle finished ground tools with care, as ground cutting edges are sharp.
