Value Collection 460-0148 M35 Cobalt Tool Bit Blank 3/4x3/4x5in

Product Description

The VALUE COLLECTION 460-0148 is a square tool bit blank ground from M35 cobalt high-speed steel. It measures 3/4 inches wide by 3/4 inches high with an overall length of 5 inches. Cobalt HSS blanks are used by machinists, toolmakers, and trade-shop professionals who grind their own cutting tools to custom profiles. The M35 cobalt alloy grade offers higher heat resistance and wear resistance compared to standard M2 HSS, making it suitable for harder workpiece materials and interrupted cuts. The blank arrives unground, ready for shaping on a bench grinder or tool cutter grinder.

This tool bit blank fits applications in manual and CNC lathe work, boring, threading, and form-tool grinding where a custom cutting edge is required. It is appropriate for job-shop environments, vocational tool-room settings, and maintenance machining operations. Machinists typically select cobalt blanks when working with stainless steel, cast iron, titanium alloys, or other materials that generate significant cutting heat. The square cross-section seats consistently in standard tool holders and grinding fixtures.

Key Features

Compatibility

Designed as a general-purpose tool bit blank for use in standard 3/4-inch square tool holders, grinding fixtures, and manual or CNC lathe toolposts that accept square HSS blanks.

Installation Notes

Grinding this blank to a finished cutting tool is performed by a qualified machinist or toolmaker using a bench grinder or tool cutter grinder equipped with appropriate grinding wheels for cobalt HSS. Eye protection and proper wheel guards are required during grinding operations. Ensure the grinding wheel is rated for HSS cobalt alloys before use. Follow your shop safety program and applicable OSHA guidelines for abrasive wheel machinery.
