Accupro 12184828 Ball End Mill 0.4331 in 4 Flute Carbide

Product Description

The ACCUPRO 12184828 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.4331-inch (11 mm) mill diameter and 4 spiral flutes, this single-end tool delivers efficient chip evacuation and smooth cutting performance. The 40-degree helix angle promotes aggressive cutting action while reducing chatter. Micrograin carbide construction provides the hardness and wear resistance needed for extended tool life in demanding materials. The uncoated finish makes it well suited to applications where coating would add unnecessary buildup or where regrinding is part of the shop workflow. Licensed machinists and CNC programmers are the primary users.

This ball end mill is used in CNC machining centers and manual milling machines for profiling, contouring, slotting, and finishing passes on ferrous and non-ferrous materials. The stub-length configuration and 0.5512-inch (14 mm) length of cut make it particularly suited to rigid setups with minimal overhang requirements. The 12 mm shank diameter provides solid tool holding in standard ER collet chucks and end mill holders. Right-hand cutting and right-hand flute direction are standard for conventional CNC toolpath strategies.

• Single-end configuration with right-hand cut and right-hand flute direction

Compatibility

Designed as an OEM-style solid carbide ball end mill fitting standard 12 mm shank tool holders, ER collet chucks, and end mill holders used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the tool holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before initiating a cutting program to confirm proper seating and avoid premature tool wear or breakage.
