Cobalt M42 square tool bit
This Cleveland C44571 bit is a non-beveled square blank made from cobalt M42 high-speed steel. It measures 3/16 inch in width and height with an overall length of 2-1/2 inches. The blank format lets machinists grind custom profiles for turning operations on a lathe.
Ground-profile limits for this blank
The 3/16-inch square cross-section sets the maximum tool size you can grind from this blank. Cobalt M42 retains hardness at higher temperatures than standard high-speed steel, extending edge life in tough alloys. The non-beveled stock requires full grinding before use.
Upgrade from standard HSS blanks
This bit replaces general-purpose high-speed steel blanks when cutting stainless steels, nickel alloys or other work-hardening materials. The jump is worth it when tool wear shortens production runs or when interrupted cuts chip standard edges. It is not for applications needing pre-formed geometries or larger tool sections.

Questions about this item
Which square tool bit size should I select for my lathe?
This bit measures 3/16 inch square by 2-1/2 inches long, so choose it when your tool holder accepts that exact cross-section and reach.
What does the M42 cobalt grade mean for cutting performance?
M42 cobalt contains 8% cobalt for high red hardness, letting the bit keep a sharp edge longer in tough steels and high-temperature alloys.
How does the non-bevelled blank design affect use?
The flat, non-bevelled end lets you grind any custom tool geometry you need — turning, facing or threading — without a preset angle limiting the shape.
