Measuring 3\/4 inch wide by 3\/4 inch high with a 5-inch overall length, this blank is supplied in a ground finish with a 10-degree bevel angle, providing a consistent, ready-to-grind surface. M42 cobalt HSS offers high red hardness and wear resistance, making it well suited for cutting harder workpiece materials where standard M2 tooling would degrade prematurely.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is used in metalworking shops, machine shops, and toolrooms where custom single-point lathe tools, boring bars, or specialty cutting tools are fabricated in-house. The square cross-section fits standard tool holders and lantern-style post systems common on engine lathes. Typical installers are machinists, tool and die makers, and grinding room technicians who grind the blank to the required geometry for turning, facing, threading, or parting operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel for superior red hardness and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eSquare cross-section at 3\/4 inch wide by 3\/4 inch high fits standard lathe tool posts and holders\u003c\/li\u003e\n  \u003cli\u003e5-inch overall length provides material for multiple regrinding cycles\u003c\/li\u003e\n  \u003cli\u003eGround finish with 10-degree bevel angle delivers a consistent starting surface for precision grinding\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit procurement for toolroom use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use tool bit blank for standard 3\/4-inch square tool holders and lantern-style tool posts used on engine lathes and manual turning machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding should be performed by a qualified machinist or toolroom technician using appropriate bench or surface grinders with HSS-rated wheels. Always use eye protection and follow safe grinding practices when profiling the blank. Ensure the tool holder set screws are properly tightened before engaging the workpiece.
