Hertel E5252012 Ball End Mill 0.1875 in 4 Flute Carbide

Product Description

The HERTEL E5252012 is a solid carbide ball end mill designed for precision milling operations in metal, alloy, and composite materials. The ball-nose geometry produces smooth curved surfaces, contoured profiles, and 3D finishing passes that flat-end tools cannot achieve. At 0.1875 inches in diameter with a 0.375-inch length of cut and a 2-inch overall length, this is a compact tool suited for fine-detail work in dies, molds, and close-tolerance components. The 4-flute configuration increases chip load per revolution and supports higher feed rates compared to 2-flute designs. Solid carbide construction provides the rigidity and wear resistance required for demanding machining environments. The double-end design extends usable tool life before replacement is necessary.

This end mill is appropriate for CNC machining centers and manual mills running ferrous and non-ferrous materials where a ball-nose profile is required. The 0.1875-inch diameter makes it well suited for narrow slots, small-radius pockets, and finish passes on complex geometry. Right-hand cutting and right-hand spiral flute direction are standard for conventional milling center setups. The uncoated finish is compatible with cutting fluid or dry machining strategies depending on the base material and shop practice.

Key Features

• Ball-nose geometry for contoured and 3D surface milling
• 4-flute spiral design supports efficient chip evacuation and higher feed rates
• Solid carbide construction for rigidity and extended wear resistance
• Double-end configuration maximizes tool usage before discard
• Right-hand cut and right-hand flute direction for standard CNC setups
• Uncoated finish suitable for use with cutting fluids or dry applications

Compatibility

Designed as a standard replacement or stocked tooling option for CNC machining centers and manual milling machines accepting a 3/16-inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Confirm collet or end mill holder bore matches the 0.1875-inch shank diameter before seating the tool. Ensure the spindle is fully powered down and locked out before changing tooling. Check runout with a dial indicator after seating to confirm proper concentricity before beginning a cut.
