Accupro 12184346 Ball End Mill 0.2344in 3 Flute Carbide

Product Description

The ACCUPRO 12184346 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous metals, alloys, and plastics. The ball nose profile generates contoured surfaces, 3D profiles, and full-radius slots that flat-end tools cannot produce. Manufactured from micrograin solid carbide, it delivers the rigidity and edge retention needed for tight-tolerance work. The 3-flute configuration balances chip evacuation with cutting stability. Key dimensions include a 0.2344-inch mill diameter, 0.75-inch length of cut, and a 40-degree helix angle. Machinists and toolroom professionals install this tool in CNC machining centers and manual mills.

This end mill suits finish and semi-finish passes on die and mold features, curved pockets, and contoured part surfaces. The 0.25-inch shank diameter fits standard ER collet chucks and end mill holders common to vertical machining centers. The single-end design and right-hand cutting direction make it a direct fit for conventional right-hand spindle setups. The uncoated micrograin carbide substrate is well suited for applications where coolant or cutting oil is applied directly, and for materials where coated tools may not be preferred.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity
• Ball nose profile for contoured surfaces, 3D profiling, and full-radius slot milling
• 3-flute design balances chip clearance and cutting stability
• 40-degree right-hand spiral helix for efficient chip evacuation
• Uncoated finish suitable for use with coolant on a wide range of work materials
• Single-end, right-hand cutting direction for standard CNC and manual mill spindles

Compatibility

Designed for use in standard 0.25-inch collet chucks and end mill holders on CNC machining centers and manual vertical mills with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and tighten to the holder manufacturer's specified procedure to prevent pullout during cutting. Inspect the cutting edges for chips or damage before each use and do not run a damaged tool.
