Value Collection 360-0049 Tool Bit Blank M2 Hss Square

Product Description

The VALUE COLLECTION 360-0049 is a square-ground tool bit blank made from M2 high speed steel, designed for machinists and tool grinders who need a ready-to-grind starting point for custom lathe, shaper, or planer tooling. Measuring 5/16 inches wide by 5/16 inches high with an overall length of 2.5 inches, this blank provides consistent stock that can be ground to a specific cutting geometry on a bench or surface grinder. The M2 grade HSS offers a reliable balance of hardness, wear resistance, and toughness suitable for general-purpose metal cutting applications.

This tool bit blank is used in machine shops, toolrooms, and maintenance environments where custom-ground cutting tools are required. It is appropriate for grinding single-point turning tools, threading tools, boring tools, or form tools for use on manual lathes and shapers. The square cross-section and ground finish allow machinists to establish accurate relief and rake angles quickly when dressed on a tool grinder.

Key Features

• M2 high speed steel construction for strong wear resistance in general-purpose metal cutting
• Square cross-section at 5/16 inches wide by 5/16 inches high for consistent geometry when grinding
• Ground finish provides accurate stock dimensions straight out of the package
• 2.5-inch overall length gives sufficient material for grinding multiple tool profiles over the life of the blank
• Single-piece packaging suitable for toolroom use or individual replacement

Compatibility

Designed as an OEM-style replacement or standard tool bit blank for use in tool holders and grinder fixtures accepting 5/16-inch square shank blanks.

Installation Notes

Tool bit blanks are ground to shape by a qualified machinist or toolmaker using a bench grinder or surface grinder equipped with an appropriate abrasive wheel rated for high speed steel. Wear eye protection and use a tool rest when grinding. Dress the grinding wheel before use to ensure a flat, true surface. Allow the blank to cool between grinding passes to prevent overheating and loss of hardness at the cutting edge.
