Lathe Tool Blank Cobalt
This Cleveland lathe tool blank is made from M42 cobalt high-speed steel for metal-cutting applications. It suits machinists and maintenance workshops that grind custom profiles for turning, boring or facing operations. The rectangular blank arrives unshaped so the user can form the exact geometry required for a specific job.
Rectangular 1/4 by 1/2 Inch
The blank measures 1/4 inch wide by 1/2 inch high and 6 inches long with a non-bevelled right-and-left-hand profile. Cobalt alloy retains hardness at elevated cutting temperatures, reducing the frequency of regrinds during extended production runs. The uniform cross-section simplifies clamping in standard tool holders without additional adapters.
Replaces Worn Ground Tooling
Shops replace exhausted carbon-steel or lower-grade HSS blanks with this M42 grade when longer edge life cuts downtime on repetitive batches. The upgrade is worthwhile where workpiece materials such as stainless alloys or high-temperature metals accelerate wear on conventional tool bits.
