Accupro 12184418 Ball End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12184418 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. With a 0.1875-inch (3/16 inch) cutting diameter and a 0.375-inch length of cut, this three-flute tool is built for contouring, profiling, and finishing passes on hardened and difficult-to-machine materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and wear resistance needed for demanding CNC milling applications. It ships uncoated and is configured as a single-end tool.

This end mill is suited for use in CNC machining centers and manual mills where tight-tolerance 3D contouring or radius work is required. The ball-nose geometry makes it a standard choice for die and mold work, curved surface finishing, and slotting operations where a full-radius profile is needed. Its compact 0.1875-inch diameter makes it appropriate for fine-detail work and narrow-pocket applications in ferrous and non-ferrous materials. The 3/16-inch shank diameter matches the cutting diameter for straightforward collet setup.

Key Features

• 0.1875-inch ball-nose cutting diameter for precise radius profiling
• 3 flutes with 40-degree right-hand helix for efficient chip evacuation
• Micrograin solid carbide construction for hardness and edge retention
• 0.375-inch length of cut supports controlled depth passes
• 2-inch overall length provides adequate reach without sacrificing rigidity
• Uncoated finish — compatible with cutting fluids or dry cutting as application demands

Compatibility

Designed as an OEM-style replacement or standard-use solid carbide ball end mill compatible with 3/16-inch collets and toolholders in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the 3/16-inch shank fully in a matching collet or end mill holder and torque to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, particularly for finish-pass or tight-tolerance operations.
