Cleveland C44516 Tool Bit Blank 3/8 in Square M2 Hss

Product Description

The CLEVELAND C44516 is a square-ground tool bit blank made from M2 high speed steel, intended for machinists and toolroom professionals who grind their own cutting tool profiles. The blank measures 3/8 inches wide by 3/8 inches high with an overall length of 3 inches, providing ample stock for custom tool shaping. M2 grade high speed steel offers a practical balance of hardness, wear resistance, and toughness for general-purpose single-point and form tool applications. The 10-degree bevel angle and ground finish deliver a consistent starting geometry that reduces the time required to reach a final edge during bench or surface grinding.

This tool bit blank is suited for use in manual lathes, boring bars, shaper setups, and other single-point tooling applications common in job shops, maintenance machining, and vocational training environments. Machinists typically purchase blanks of this size for turning, facing, threading, and parting operations where a standard insert holder is not appropriate or where a custom ground form is required. The 3/8 inch cross-section fits standard lathe tool posts and holders designed for that shank size.

Key Features

• M2 high speed steel construction for reliable hardness and wear resistance in general machining
• Square ground profile with a 10-degree bevel angle provides a consistent starting geometry
• 3/8 inch by 3/8 inch cross-section fits standard tool posts and holders for that shank size
• 3 inch overall length gives adequate stock for multiple regrinds over the tool life
• Ground finish reduces bench grinding time needed to reach a working cutting edge

Compatibility

Designed as an OEM-style replacement or stock blank for manual lathes and single-point tooling setups that accept a 3/8 inch square shank tool bit.

Installation Notes

Tool bit blanks are ground to final geometry by a machinist using a bench grinder or surface grinder before installation. Ensure the lathe or machine is powered off and locked out before seating or adjusting any tool bit. Secure the blank firmly in the tool post or holder to the manufacturer-recommended clamping method before cutting. Eye protection and appropriate grinding wheels rated for high speed steel are required during the grinding process.
