Value Collection 460-0179 M35 Cobalt Tool Bit Blank 1x1x7 in

Product Description

The VALUE COLLECTION 460-0179 is a square tool bit blank machined from M35 cobalt high-speed steel, intended for use in manual and CNC grinding operations where a custom cutting profile is required. Measuring 1 inch wide by 1 inch high by 7 inches overall length, this blank gives machinists and toolmakers a solid, ready-to-grind starting point. M35 cobalt steel offers improved heat resistance and hardness retention compared to standard M2 HSS, making it suitable for harder workpiece materials and heavier interrupted cuts. The 460-0179 is used wherever a shop needs to produce a one-off or specialized form tool ground to a specific geometry.

This tool bit blank is suited for jobbing machine shops, maintenance shops, and production environments running manual engine lathes, turret lathes, and similar metal-cutting machines. The square cross-section fits standard toolpost and boring bar holders designed for 1-inch shank tooling. Machinists grind the blank to a desired rake, relief, and nose radius using a bench or pedestal grinder with an appropriate wheel for cobalt HSS. The 7-inch length provides enough material for multiple regrinds over the tool's service life.

Key Features

• M35 cobalt high-speed steel construction for improved red hardness and wear resistance
• Square cross-section, 1 inch x 1 inch, fits standard 1-inch toolpost holders
• 7-inch overall length allows multiple grinding cycles before replacement
• Unground blank format enables custom geometry to be applied by the end user
• Consistent material stock for predictable grinding behavior

Compatibility

Designed as a general-purpose unground blank for use in standard 1-inch square toolpost and boring bar setups on manual and CNC lathes requiring M35 cobalt HSS tooling.

Installation Notes

Grinding of this blank should be performed by a qualified machinist using appropriate wheel speeds and coolant or air-blast to prevent overheating the cutting edge. Secure the blank firmly in a tool grinder rest or fixture before grinding to maintain consistent angles. Eye protection and a properly dressed grinding wheel rated for high-speed steel are required. No installation into a machine tool should occur until the ground tool has been inspected for cracks, proper relief, and edge geometry.
