Value Collection 461-0035 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0035 is a rectangular tool bit blank ground from M35 cobalt high-speed steel, intended for machinists and toolroom professionals who grind their own single-point cutting tools to custom geometry. Measuring 0.25 inches wide, 0.75 inches high, and 5 inches in overall length, this blank provides the raw stock needed to profile lathe bits, boring tools, and form tools to exact specifications. The M35 cobalt alloy delivers elevated red hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for cutting harder workpiece materials including stainless steels, high-temperature alloys, and hardened ferrous metals.

This tool bit blank is used in machine shop environments, toolroom operations, and maintenance machining applications where pre-ground inserts do not meet the required profile. Machinists grind the blank on a bench or pedestal grinder to create custom rake angles, clearance angles, and nose radii suited to the specific workpiece material and lathe setup. The rectangular cross-section allows flexible orientation in standard tool holders and lantern-style tool posts common on engine lathes.

Key Features

• M35 cobalt high-speed steel for improved red hardness and extended tool life on tough materials
• Rectangular cross-section measures 0.25 inches wide by 0.75 inches high for flexible holder fitment
• 5 inch overall length provides generous grinding stock for multiple regrinds
• Unground blank stock allows custom geometry profiling to match specific cutting applications
• Consistent material grade supports predictable grindability and edge retention

Compatibility

Designed as a standard rectangular tool bit blank for use in engine lathe tool holders, lantern tool posts, and toolroom grinding applications requiring a 0.25 inch wide by 0.75 inch high cross-section profile.

Installation Notes

Grinding of tool bit blanks should be performed by a qualified machinist using appropriate bench or pedestal grinding equipment with wheel grades suited for high-speed steel. Eye protection and proper wheel guards must be in place during all grinding operations. Allow the blank and wheel to cool periodically to prevent drawing the temper of the cobalt steel. Secure the blank firmly in a tool grinding fixture or rest to maintain consistent geometry throughout the grind.
