Value Collection 360-0039 Tool Bit Blank 1/4 in M2 Hss 8 in

Product Description

The VALUE COLLECTION 360-0039 is a square tool bit blank ground from M2 high speed steel, designed for machinists and toolmakers who need a reliable starting stock for custom cutting tool fabrication. Measuring 0.25 inches wide by 0.25 inches high with an overall length of 8 inches, this blank provides ample material for grinding single-point turning tools, boring bars, threading tools, and other custom profiles. The M2 grade high speed steel offers a strong balance of hardness, toughness, and wear resistance, making it well-suited for general-purpose metal cutting applications on manual and CNC lathes.

This tool bit blank is used in machine shops, maintenance facilities, and vocational training environments where operators grind their own cutting tools to custom geometries. It is appropriate for turning, facing, and profiling operations on ferrous and non-ferrous workpiece materials. The square cross-section suits standard tool holders and lantern-style toolposts commonly found on engine lathes. Machinists, toolmakers, and apprentices working in production or job-shop settings will find this blank a practical stock item for tool room use.

Key Features

• M2 high speed steel construction for strong wear resistance and hardness retention at elevated cutting temperatures
• Square cross-section at 0.25 inches by 0.25 inches fits standard lathe tool holders and toolposts
• 8 inch overall length provides generous stock for grinding multiple tools from a single blank
• Ground finish ensures consistent dimensional accuracy across the blank cross-section
• Single-piece packaging suits individual tool room replenishment or low-volume restocking

Compatibility

Designed as a general-purpose tool bit blank for use in standard lathe tool holders and toolposts accepting 0.25 inch square shank tooling.

Installation Notes

Tool bit blanks are shaped on a bench or pedestal grinder by a qualified machinist or toolmaker using appropriate grinding wheels rated for high speed steel. Eye protection and a properly dressed grinding wheel are required during the grinding process. Secure the blank firmly in a tool grinding fixture or rest to maintain consistent relief and rake angles. Allow the blank to cool regularly during grinding to prevent overheating and softening of the cutting edge.
