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.

Questions about this item
How often will the .75 in HSS ball nose need resharpening?
Resharpen when the flutes no longer produce a clean radius; high-speed steel can be reground multiple times before replacement.
What stops a full-depth slot in hardened steel with this uncoated 2-flute tool?
Heat buildup in the uncoated HSS body limits sustained feed rates before the edge softens.
Does the bright finish run hotter than coated mills during a long production run?
Yes, the uncoated surface generates more friction and heat, so use flood coolant and reduce speed for extended cuts.
