Cleveland C42186 Ball End Mill 0.1875 in 2 Flute Hss

Product Description

The CLEVELAND C42186 is a double-end ball end mill designed for precision finishing operations in ferrous and non-ferrous materials. Built from high speed steel with an uncoated surface finish, it features a 0.1875-inch diameter, a 30-degree helix angle, and two spiral flutes for efficient chip evacuation. The double-end configuration effectively doubles usable tool life before replacement is required. With a 3/8-inch shank diameter and 3.25-inch overall length, this end mill is sized for standard collet chucks and milling machine spindles. It is intended for use by machinists and tool-and-die professionals performing finishing passes on cast iron, steel, and non-ferrous metals.

This end mill fits standard vertical and horizontal milling setups, CNC machining centers, and manual knee mills equipped with a 3/8-inch collet or end mill holder. Its regular-length geometry suits close-tolerance finishing work where controlled deflection and surface finish quality are priorities. Primary workpiece materials include cast iron, steel, and non-ferrous metals. The HD-2B series designation indicates a heavy-duty two-flute ball-nose configuration suited for contour milling, 3D profiling, and slot finishing at moderate depths of cut.

Key Features

• 0.1875-inch (3/16-inch) ball nose diameter for contour and radius milling
• Double-end design extends tool life with two usable cutting ends
• High speed steel construction provides toughness across a range of workpiece materials
• 30-degree right-hand helix with spiral flutes for smooth chip flow during finishing passes
• Uncoated finish suitable for use with or without cutting fluid
• HD-2B series regular-length geometry minimizes deflection in precision finishing applications

Compatibility

Compatible with milling machines and CNC machining centers using a 3/8-inch collet or end mill holder. Suited for finishing operations on cast iron, steel, and non-ferrous metals.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the spindle is fully stopped and locked before inserting or removing the end mill from the collet or holder. Seat the shank fully into the collet and torque the drawbar or collet nut to the machine manufacturer's specification. Inspect both cutting ends for chipping or wear before use and do not run a damaged tool.
