Value Collection 460-2200 Tool Bit Blank M35 Cobalt 8 in

Product Description

The VALUE COLLECTION 460-2200 is a square tool bit blank ground from M35 cobalt high-speed steel, measuring 0.25 inches wide by 0.25 inches high with an overall length of 8 inches. Tool bit blanks are unground stock used by machinists and tool grinders to fabricate custom single-point cutting tools, form tools, and lathe bits to exact geometry. The M35 cobalt alloy grade provides elevated heat resistance and hardness retention compared to standard M2 HSS, making it well suited for interrupted cuts and harder work materials. A licensed machinist or experienced tool grinder is the typical end user for this type of stock.

This blank is appropriate for use in manual and CNC lathe toolposts, boring bar setups, and custom toolholder applications where a ground-to-spec cutting edge is required. The square cross-section suits general-purpose single-point turning, threading, and form-tool applications. It is commonly used in job shops, tool rooms, and maintenance machining environments where off-the-shelf insert tooling does not meet the required profile.

Key Features

• M35 cobalt high-speed steel construction for improved hot hardness and wear resistance
• Square cross-section at 0.25 inches wide by 0.25 inches high
• 8-inch overall length provides ample stock for multiple grinds or longer tool profiles
• Unground blank format allows custom geometry to be applied by the end user
• Suitable for turning, threading, and form-tool fabrication on manual and CNC lathes

Compatibility

Designed as a general-purpose tool bit blank for use in any toolpost, holder, or fixture that accepts a 0.25-inch square shank tool bit.

Installation Notes

Grinding tool bit blanks requires a bench or surface grinder equipped with an appropriate aluminum oxide or CBN wheel rated for high-speed steel. Eye protection and a wheel guard must be used at all times during grinding operations. Allow the blank to cool periodically during grinding to prevent annealing the cutting edge. Secure the finished tool bit firmly in the toolpost before engaging the workpiece.
