Cobalt M42 Square Tool Bit
This Cleveland C44549 Cobalt M42 square tool bit is a precision ground lathe tool blank made from high-speed cobalt steel. The M42 grade provides excellent wear resistance and red hardness for demanding metal cutting operations. It measures 7/16 inch square by 3-1/2 inches overall length. The non-beveled design suits both right-hand and left-hand tool holder configurations.
For Manual Lathe Operators
Machinists producing custom tool profiles for turning, facing or boring on manual engine lathes will appreciate the ready-to-grind blank. CNC shops relying exclusively on indexable carbide inserts gain no advantage from a solid cobalt blank. Buyers needing pre-formed cutting geometry or coated inserts should select a different product type.
Ready-to-Grind Blank
The square cross-section allows the user to grind any required rake, clearance or nose radius angles for specific workpiece materials. No factory bevels or chipbreakers are present, so the machinist controls the complete tool geometry. This flexibility supports one-off jobs and prototype work where standard inserts are unavailable or uneconomical.
