Value Collection 360-0128 Tool Bit Blank M2 Hss 5/8 in Square

Product Description

The VALUE COLLECTION 360-0128 is an M2 high speed steel tool bit blank designed for machinists and toolmakers who grind their own cutting tools to custom profiles. Measuring 5/8 inch wide by 5/8 inch high with a 4-1/2 inch overall length, this square-profile blank provides the raw stock needed to create lathe bits, boring tools, fly cutters, and other single-point cutting tools. M2 grade high speed steel offers a reliable balance of red hardness, wear resistance, and toughness for general-purpose metal cutting operations. The blank arrives ground to consistent dimensions, reducing setup time before profile grinding begins.

This tool bit blank is suited for use in manual and CNC lathes, milling setups, and tool-and-die applications across job shops, maintenance facilities, and production environments. Machinists select square blanks of this size for medium-duty turning, threading, and form tool applications where a custom grind is required to match a specific part geometry or cutting condition. The ground finish ensures dimensional accuracy right out of the package.

Key Features

• M2 high speed steel construction for reliable hardness and wear resistance in general metal cutting
• Square cross-section at 5/8 inch wide by 5/8 inch high suits medium-duty lathe and milling tool applications
• 4-1/2 inch overall length provides adequate stock for grinding multiple tool profiles over the life of the blank
• Ground finish ensures consistent dimensional accuracy for precise tool geometry work
• Sold individually, allowing purchase of exact quantities needed for the job

Compatibility

Designed as a standard-profile replacement or stock blank for tool holders and lathe tool posts that accept 5/8 inch square shank cutting tools.

Installation Notes

Tool bit blanks are ground to final cutting geometry by a qualified machinist using a bench or pedestal grinder equipped with appropriate grinding wheels for high speed steel. Always wear eye protection and follow shop safety procedures during grinding operations. Secure the blank firmly in a tool holder or vise before use to prevent movement during cutting. Inspect the finished tool edge for cracks or chips before mounting in any machine tool.
