Value Collection 360-0057 Tool Bit Blank 5/16 in Square M2 Hss

Product Description

The VALUE COLLECTION 360-0057 is a square tool bit blank made from M2 high speed steel, ground to a uniform cross-section for use in manual or CNC toolroom applications. Measuring 5/16 inches wide by 5/16 inches high with an overall length of 8 inches, this blank provides machinists and tool grinders with raw stock to profile, regrind, or shape into custom cutting tools. M2 high speed steel delivers strong wear resistance and edge retention at elevated cutting temperatures, making it a reliable base material for lathe tools, boring bars, fly cutters, and similar tooling. The square ground profile ensures consistent seating in standard tool holders and grind fixtures.

This blank is suited for toolroom and production environments where custom or reground cutting tools are required. Machinists use blanks like this to hand-grind turning tools, parting tools, threading tools, and other single-point cutters to exact geometry. The 8-inch length allows multiple regrinds or the fabrication of longer tooling profiles. Both job shops and maintenance facilities stock M2 blanks as a standard consumable for keeping cutting tool inventory ready without relying on pre-ground profiles.

Key Features

Compatibility

Designed as a standard-size tool bit blank for use in 5/16-inch tool holders, grind fixtures, and toolpost setups on manual lathes and milling machines requiring square HSS tool stock.

Installation Notes

Tool bit blanks are shaped and sharpened by a machinist or tool grinder before use in cutting operations. Use appropriate bench grinders or surface grinders with wheels rated for high speed steel. Ensure the grinding area is clear of flammable materials and eye protection is worn during all grinding operations. The finished tool should be inspected for proper geometry and relief angles before installation in any machine tool holder.
