Value Collection 461-0002 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0002 is a rectangle ground tool bit blank machined from M35 cobalt high-speed steel. Measuring 0.25 inches wide, 0.375 inches high, and 2.5 inches overall length, this blank is intended for machinists and toolmakers who grind custom cutting profiles to suit specific lathe, shaper, or milling applications. M35 cobalt steel offers elevated heat resistance and hardness retention compared to standard M2 high-speed steel, making it suitable for harder work materials and interrupted cuts. The ground finish ensures consistent dimensional accuracy across the blank's cross-section before the final profile grind.

This tool bit blank is used in machine shops, maintenance facilities, and vocational settings where operators grind their own single-point cutting tools. It is appropriate for general-purpose turning, threading, parting, and form-tool applications on manual lathes and shapers. The rectangle cross-section fits standard tool holders and lantern-style post holders commonly found in manual metalworking setups. Sold individually, it suits both low-volume toolroom use and bench-level tool fabrication tasks.

Compatibility

Designed as a general-purpose rectangle tool bit blank suitable for use in standard tool holders accepting a 0.25 inch wide by 0.375 inch high shank profile on manual lathes and shapers.

Installation Notes

Grinding tool bit blanks is performed by qualified machinists or toolmakers using a bench or pedestal grinder fitted with appropriate grinding wheels for high-speed steel. Always wear face protection and follow safe grinding practices when shaping the cutting profile. Secure the blank firmly in the tool holder and verify proper clearance and rake angles before taking a cut. Ensure the machine is powered down and locked out before changing or adjusting the tool bit in the holder.
