Value Collection 460-11484 M35 Cobalt Tool Bit Blank 5/8in

Product Description

The VALUE COLLECTION 460-11484 is a square tool bit blank ground from M35 cobalt high-speed steel. It measures 5/8 inches wide by 5/8 inches high with a 4-1/2 inch overall length. Tool bit blanks are unground stock used by machinists and tool grinders to fabricate custom cutting tool profiles for lathes, shapers, and boring bars. The M35 grade cobalt alloy provides higher heat resistance and hardness retention compared to standard M2 high-speed steel, making this blank well suited for grinding tools intended to cut hard or abrasive workpiece materials.

This bit blank is appropriate for job shops, tool rooms, and production environments where custom single-point or form cutting tools are required. The square cross-section is the most common geometry for lathe tool holders and quick-change toolpost systems. Machinists grind the blank to the desired relief, rake, and nose geometry on a bench or pedestal grinder before use. The 4-1/2 inch length provides adequate stock for grinding multiple tool profiles over the life of the blank.

Key Features

• M35 cobalt high-speed steel construction for improved hot hardness and wear resistance
• Square cross-section at 5/8 inches x 5/8 inches fits standard lathe tool holders and quick-change toolposts
• 4-1/2 inch overall length provides generous stock for custom grinding
• Unground blank allows machinists to form any cutting geometry needed for the application
• Weighs 0.56 pounds — compact and easy to handle at the grinder

Compatibility

Designed as a general-purpose tool bit blank for use in any lathe tool holder, quick-change toolpost, or boring bar setup that accepts a 5/8 inches square shank.

Installation Notes

Grinding tool bit blanks should be performed by a qualified machinist using appropriate wheel dressing and personal protective equipment including eye protection. Secure the blank firmly in a tool rest or grinding jig to maintain consistent relief and rake angles. Allow the blank to cool frequently during grinding to prevent drawing the temper of the cobalt steel. Finished ground tools should be inspected for proper geometry before use in the machine.
