Value Collection 460-6111 M42 Cobalt Tool Bit Blank 1/2 in

Product Description

The VALUE COLLECTION 460-6111 is a solid M42 cobalt high-speed steel tool bit blank measuring 0.5 inches wide by 0.5 inches high with a 4-inch overall length. Supplied in a square profile, this blank is unground and ready for custom shaping by machinists and toolroom operators. M42 cobalt HSS offers elevated red hardness and wear resistance compared to standard M2 steel, making it well-suited for grinding into form tools, boring tools, threading tools, fly cutters, and other single-point cutting tools used on manual or CNC lathes and mills. Weighing approximately 0.27 pounds, this is a compact, shop-ready blank for in-house tool fabrication.

This tool bit blank is used in production and toolroom environments where machinists need to grind custom cutting geometry from raw stock. Typical applications include turning, facing, threading, and form-tool operations on lathes working with harder steels, stainless, and other difficult-to-machine alloys where cobalt-grade HSS provides a performance edge over standard high-speed steel. It is well-suited for job shops, maintenance departments, and apprentice training programs that grind their own tooling.

Key Features

• M42 cobalt HSS material grade for improved red hardness and extended tool life in demanding cuts
• Square cross-section profile at 0.5 inches by 0.5 inches for easy fixture in standard tool holders
• 4-inch overall length provides ample stock for grinding and regrinding multiple times
• Unground blank allows machinists to create custom rake, relief, and nose geometry as required
• Compact weight of 0.27 pounds for easy bench handling and grinding fixture setup

Compatibility

Designed as a general-purpose tool bit blank compatible with standard square-shank lathe tool holders and boring bar setups that accept 0.5-inch shank tooling.

Installation Notes

Grinding this blank to final geometry should be performed by a qualified machinist using a bench or pedestal tool grinder equipped with appropriate HSS grinding wheels. Wear eye protection and use the tool rest for controlled material removal. Inspect the finished cutting edge before mounting in a tool holder, and ensure the tool holder set screws are properly tightened before commencing any turning or milling operation.
