Value Collection 362-0121 Tool Bit Blank M2 Hss Round

Product Description

The VALUE COLLECTION 362-0121 is an M2 high speed steel tool bit blank designed for machinists and toolmakers who need a precision ground starting stock for custom cutting tools. With a 3/8 inch diameter and 5 inch overall length, this round blank provides sufficient material for grinding single-point lathe tools, boring bars, form tools, and specialty cutters. M2 HSS offers a balanced combination of hardness, wear resistance, and toughness suitable for general-purpose machining on steel, cast iron, aluminum, and most non-ferrous alloys. The ground finish ensures consistent diameter and surface quality straight out of the package.

This blank is suited for use in machine shops, tool rooms, and maintenance environments where off-the-shelf insert tooling does not meet the required geometry. Machinists grind the blank to a custom profile using a bench or tool and cutter grinder. It is appropriate for manual lathes, boring setups, and custom fixture tooling in both production and one-off applications. The 5 inch length allows for multiple regrinds over the service life of the blank.

Key Features

• M2 high speed steel construction for durability across a range of workpiece materials
• Ground finish provides consistent 3/8 inch diameter and smooth surface for accurate tool geometry
• Round end shape compatible with standard round tool holders and boring bar applications
• 5 inch overall length allows repeated regrinding and extended service life
• Single-piece packaging suitable for individual or small-quantity tool room stock

Compatibility

Designed as a general-purpose round tool bit blank for use in standard 3/8 inch round tool holders and boring bar sleeves on manual and CNC lathes.

Installation Notes

Grinding of HSS tool bit blanks should be performed by a qualified machinist or toolmaker using a bench grinder or tool and cutter grinder with an appropriate wheel. Secure the blank firmly in a tool rest or holding fixture before grinding to maintain consistent angles. Allow the blank to cool frequently during grinding to prevent overheating and loss of temper in the HSS material. Always wear appropriate eye protection when grinding.
