Value Collection 460-2500 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 460-2500 is a solid M35 cobalt tool bit blank ground to a square cross-section for use in custom toolgrinding applications. Measuring 0.5 inches wide by 0.5 inches high with an overall length of 8 inches, this blank gives machinists and tool grinders a consistent, high-hardness starting point for producing single-point lathe tools, boring bars, and other custom cutting tools. M35 cobalt high-speed steel offers improved heat and wear resistance compared to standard M2 HSS, making it well suited for harder workpiece materials and higher cutting speeds.

This tool bit blank is used in machine shops, tool rooms, and production environments where operators need to grind their own cutting geometry to match a specific operation. Typical applications include turning, threading, and form-tool work on manual lathes. The square cross-section allows the blank to be seated securely in standard tool holders and grinder fixtures without additional modification prior to grinding.

Key Features

• M35 cobalt high-speed steel construction for improved heat and wear resistance over standard HSS
• Square cross-section at 0.5 inches wide by 0.5 inches high for consistent seating in tool holders
• 8-inch overall length provides generous material for grinding multiple tool profiles from a single blank
• Uniform ground finish supports accurate, repeatable tool geometry when sharpening

Compatibility

Designed as a standard-size square tool bit blank suitable for use with manual lathes and tool grinding setups that accept 0.5-inch square shank tooling.

Installation Notes

Grinding tool bit blanks is typically performed by machinists or tool grinders using bench or pedestal grinding equipment fitted with appropriate aluminum oxide or CBN wheels. Always wear eye protection and use the tool rest when grinding. Inspect the blank for cracks or chips before and after grinding. Follow shop-specific procedures for heat management during the grinding process to avoid drawing the temper of the cobalt steel.
