Value Collection 460-0067 M35 Cobalt Tool Bit Blank 3/8x3in

Product Description

The VALUE COLLECTION 460-0067 is a square tool bit blank ground from M35 cobalt high-speed steel. It measures 3/8 inches wide by 3/8 inches high with a 3-inch overall length. Tool bit blanks are unground stock used by machinists and tool grinders to fabricate custom single-point cutting tools, form tools, and specialty lathe bits. The M35 cobalt alloy provides improved heat resistance and hardness retention compared to standard M2 high-speed steel, making it well-suited for interrupted cuts and harder workpiece materials. Weighing 0.12 pounds, this blank ships as a single piece and is ready for bench grinding to a desired profile.

This blank is appropriate for use in manual and CNC lathe tool holders, boring bars, and grooving setups where a custom-ground bit profile is required. It is commonly used in job shops, maintenance machining environments, and toolroom applications where off-the-shelf insert geometry does not meet the required form. Machinists working with stainless steel, hardened alloys, and cast iron frequently choose M35 cobalt blanks for their improved wear characteristics under elevated cutting temperatures.

Key Features

• M35 cobalt high-speed steel construction for improved heat and wear resistance over standard HSS
• Square cross-section at 3/8 inches x 3/8 inches for versatile tool holder compatibility
• 3-inch overall length provides adequate stock for grinding multiple tool profiles over the blank's service life
• Unground blank format allows custom relief angles, rake angles, and nose radii to be applied by the end user
• Weighs 0.12 pounds — compact and easy to handle at the bench grinder

Compatibility

Designed as a general-purpose tool bit blank for use in standard 3/8-inch tool holders and toolroom grinders where square HSS or cobalt blanks of this cross-section are specified.

Installation Notes

Tool bit blanks require grinding by a qualified machinist or toolroom technician before use as a cutting tool. Use appropriate wheel dressing and personal protective equipment when grinding cobalt HSS on a bench or surface grinder. Secure the blank firmly in a tool holder or grinding fixture before machining to prevent movement. Do not use an unground blank directly as a cutting tool.
