Hertel E7110012 Ball End Mill 0.1875 in 2 Flute Cobalt

Product Description

The HERTEL E7110012 is a single-end ball end mill designed for precision milling operations in metalworking and machining applications. Built from M42 cobalt high-speed steel and coated with TiCN, this tool handles harder workpiece materials and elevated cutting temperatures better than uncoated HSS tooling. The ball-nose geometry produces contoured surfaces, slots, and 3D profiles. Key dimensions are 0.1875 inches in cutting diameter, a 0.5-inch length of cut, and a 3/8-inch shank diameter, giving it a compact profile suited for close-tolerance work. It is installed by machinists in CNC machining centers and manual mills.

This end mill is used in shops producing dies, molds, and precision machined components where contoured or radius-bottom cuts are required. The 2-flute configuration provides adequate chip clearance when milling softer metals and non-ferrous alloys, and the right-hand cutting direction suits standard spindle rotation. With a 2.375-inch overall length and a 3/8-inch straight shank, it fits standard collet and end mill holders found on most vertical machining centers and knee mills. It is well suited for light finishing passes and semi-finish profiling work.

Key Features

• M42 cobalt steel construction for improved heat and wear resistance over standard M2 HSS
• TiCN coating reduces friction and extends tool life in ferrous and hardened materials
• Ball-nose geometry produces smooth contoured surfaces and radius-bottom slots
• 2-flute design promotes chip evacuation in slotting and profiling cuts
• Right-hand cut and right-hand flute direction for use in standard CNC and manual mill setups
• Single-end configuration with a 3/8-inch shank for compatibility with common collet systems

Compatibility

Designed as an OEM-style replacement or direct tooling solution for vertical machining centers, CNC mills, and manual knee mills accepting a 3/8-inch straight-shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set-screw holder is torqued per the holder manufacturer's specifications before operation. Inspect the cutting edges and coating for chips or wear before each use.
