Cleveland C44527 Tool Bit Blank M2 Hss 7/8in Square 6in

Product Description

The CLEVELAND C44527 is a square tool bit blank machined from M2 high-speed steel and ground to close tolerances on all faces. Measuring 7/8 inches wide by 7/8 inches high with a 6-inch overall length, this blank gives machinists and tool grinders the raw stock needed to profile custom single-point cutting tools, boring bars, and form tools. M2 HSS offers a strong balance of wear resistance, toughness, and red hardness, making it a dependable choice for general-purpose cutting tool fabrication across a wide range of shop applications.

This tool bit blank is suited for use in manual lathes, turret lathes, and tool-and-die operations where custom ground tooling is required. The square cross-section and ground finish allow the blank to seat consistently in standard tool holders and lantern-style post holders. Typical users include machinists, toolmakers, and apprentice shops that grind their own tooling to specific geometries rather than relying on indexable insert systems.

Key Features

• M2 high-speed steel construction for reliable wear resistance and toughness in cutting tool applications
• Square cross-section at 7/8 inches by 7/8 inches for consistent seating in standard tool posts and holders
• 6-inch overall length provides ample stock for grinding multiple tool profiles from a single blank
• Ground finish on all surfaces ensures accurate fitment and reduces prep time before grinding
• Sold individually, allowing procurement in exact quantities needed

Compatibility

Designed as a general-purpose tool bit blank for use in standard 7/8-inch tool holders and lathe tool posts requiring a square shank profile.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or toolmaker using a bench or tool grinder with appropriate grinding wheels rated for high-speed steel. Secure the blank firmly in a vise or tool grinding fixture before grinding to prevent movement and maintain accurate angles. Always wear eye protection and follow shop safety procedures when grinding HSS tooling. Finished tools should be inspected for proper geometry before installation in the machine tool.
