Cleveland C44513 Tool Bit Blank M2 Hss Square Ground

Product Description

The CLEVELAND C44513 is a square-ground tool bit blank made from M2 high speed steel, intended for use as raw stock that machinists and tool grinders shape into custom single-point cutting tools, form tools, and specialty bits. Measuring 0.25 inches wide by 0.25 inches high with an overall length of 2.5 inches, this blank provides a consistent, ground finish that allows accurate profiling with minimal additional prep. M2 HSS offers a well-established balance of wear resistance, toughness, and red hardness, making it a reliable choice for general-purpose cutting tool fabrication across a wide range of shop environments.

This tool bit blank is suited for use in machine shops, toolrooms, and maintenance environments where custom cutting geometry is required. It is commonly used to produce lathe tools, boring bars, threading tools, and other single-point cutting inserts ground to a specific profile. The square cross-section and ground surfaces provide a stable reference when setting up on a bench grinder or tool and cutter grinder. Both production machinists and maintenance technicians working with manual lathes and mills will find this blank a standard starting point for custom tooling.

Key Features

• M2 high speed steel construction for reliable wear resistance and toughness in cutting applications
• Square-ground finish provides accurate, consistent surfaces for precise tool grinding
• 0.25 inch x 0.25 inch cross-section suits standard small-bore tool holders and grinder fixtures
• 2.5 inch overall length offers sufficient stock for grinding multiple tool profiles over the life of the blank
• Ready-to-grind condition reduces prep time before custom geometry is applied

Compatibility

Designed as a standard tool bit blank for use in 0.25 inch tool holder slots on manual lathes, toolroom mills, and similar machine tool setups requiring custom-ground single-point cutting tools.

Installation Notes

Tool bit blanks are ground to shape by a qualified machinist or tool grinder using a bench grinder, surface grinder, or tool and cutter grinder with appropriate abrasive wheels rated for high speed steel. Ensure the grinding wheel is dressed and the work rest is properly adjusted before beginning. Use appropriate eye protection and follow shop safety procedures when grinding. Allow the blank to cool during grinding to prevent overheating, which can soften the cutting edge.
