Cleveland C42132 2-Flute HSS Ball Nose Single End Mill .75 in

Cleveland C42132 Ball Nose End Mill

The Cleveland C42132 is a .75 inch diameter ball nose end mill manufactured from high speed steel for general milling applications. Its two flute design provides efficient chip evacuation in slots and pockets. The uncoated bright finish suits short runs and softer workpiece materials. Machinists and maintenance technicians use this single end tool for contouring and profiling tasks.

Uncoated High Speed Steel Construction

The high speed steel substrate offers toughness and resistance to chipping during interrupted cuts. Without a coating the tool runs cooler in low speed or manual operations where heat buildup is minimal. The bright surface allows visual inspection of wear and simplifies regrinding when the cutting edges dull. This accessory ships directly from the supplier as a new item.

High Speed Steel Milling Limits

High speed steel tools lose hardness rapidly above moderate cutting temperatures which restricts their use to lower surface speeds. The uncoated surface provides no thermal barrier so flood coolant or mist is required for sustained production work. Two flutes limit feed rates compared to multi flute designs when finishing hardened steels or exotic alloys. Buyers needing higher material removal rates or extended tool life in abrasive materials should evaluate coated carbide alternatives.
