Value Collection 460-0021 M35 Cobalt Tool Bit Blank 3/16in

Product Description

The VALUE COLLECTION 460-0021 is a square tool bit blank machined from M35 cobalt high-speed steel. It measures 3/16 inches wide by 3/16 inches high with a 2-1/2 inch overall length. Tool bit blanks are unground stock used by machinists and toolmakers to fabricate custom single-point cutting tools, form tools, and lathe bits ground to a specific profile. M35 cobalt steel offers greater heat resistance and hardness retention than standard M2 high-speed steel, making it well suited for interrupted cuts and harder workpiece materials. The square cross-section allows the bit to be ground on any face to achieve the desired cutting geometry.

This bit blank is intended for use in manual lathes, automatic screw machines, and toolroom applications where a custom-ground cutting edge is required. Machinists, tool grinders, and tool-and-die professionals typically keep a supply of these blanks on hand for grinding to specific profiles as jobs demand. The compact 2-1/2 inch length fits standard tool holders and block-style tool posts common in general-purpose turning and facing operations.

Key Features

• M35 cobalt high-speed steel for improved heat and wear resistance over standard HSS
• Square cross-section allows grinding on any face for flexible tool geometry
• 3/16 inches x 3/16 inches cross-section suits small-bore and light-duty turning applications
• 2-1/2 inch overall length fits compact tool holders and block tool posts
• Unground blank gives machinists full control over final cutting geometry

Compatibility

Designed as a general-purpose unground blank for use in standard tool holders accepting 3/16 inch square shank tool bits on manual lathes and toolroom machines.

Installation Notes

Grinding tool bit blanks should be performed by qualified machinists using appropriate bench or tool-and-cutter grinders with suitable grinding wheels rated for cobalt high-speed steel. Always wear eye protection and ensure the grinder's work rest is properly adjusted before grinding. Power down and lock out any machine tool before installing or changing a cutting tool bit.
