Value Collection 361-0020 M2 Hss Tool Bit Blank 1/4x1/2x4

Product Description

The VALUE COLLECTION 361-0020 is a rectangle ground tool bit blank made from M2 high speed steel, intended for use in custom tooling applications where machinists grind the cutting geometry to suit a specific job. Measuring 0.25 inches wide, 0.5 inches high, and 4 inches in overall length, this blank provides a solid starting point for single-point turning tools, boring bars, threading tools, and other custom-ground cutting tools. M2 high speed steel offers a balanced combination of wear resistance, toughness, and grindability that suits a wide range of general machining operations on steel, cast iron, aluminum, and similar materials. The ground finish ensures dimensional accuracy before the machinist applies a final cutting edge.

This tool bit blank is suited for manual lathes, screw machines, and manual milling setups where the operator grinds a custom profile. It is commonly used in job shops, maintenance machining environments, and vocational or training settings. The rectangle cross-section is a standard form that fits most tool bit holders and lantern-style tool posts designed for 0.25-inch wide stock. Machinists working on light turning, threading, or form-tool applications will find this blank a practical starting material.

Key Features

• M2 high speed steel construction for good wear resistance and grindability across common work materials
• Ground finish provides accurate dimensions before final tool sharpening
• Rectangle cross-section fits standard tool bit holders and lantern tool posts
• 0.25 inches wide by 0.5 inches high cross-section suits light to medium turning applications
• 4-inch overall length provides material for resharpening over the tool life

Compatibility

Designed as an OEM-style replacement or standard consumable for use in manual lathe tool posts and screw machine setups that accept 0.25-inch wide rectangular tool bit blanks.

Installation Notes

Tool bit blanks require grinding to a finished cutting geometry before use; this is typically performed by a machinist using a bench or pedestal grinder with appropriate wheel selection for high speed steel. Ensure the lathe or machine is fully powered down and locked out before installing or adjusting any tooling. Secure the ground blank firmly in the tool holder to the depth recommended by the holder manufacturer before starting a cut. Eye protection and appropriate PPE are required during the grinding process.
