Accupro 12184128 Ball End Mill 0.25in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12184128 is a single-end ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles. Built from micrograin solid carbide and coated with TiCN for extended tool life and heat resistance, it carries a 0.25-inch diameter and a 40-degree helix angle optimized for chip evacuation and smooth cutting action. With 2 flutes and a right-hand cutting direction, this end mill is suited for medium-to-high-speed CNC machining operations across a range of ferrous and non-ferrous workpiece materials. Machinists and tooling technicians working in job shops, production machining, and mold-and-die applications will find it a dependable choice for finish and semi-finish passes.

This end mill is used in vertical and horizontal CNC machining centers for operations requiring a ball-nose profile, including 3D contouring, core and cavity work, and radius milling. Its stub-length classification and 0.375-inch length of cut make it appropriate for applications with shorter reach requirements where rigidity is a priority. The 0.25-inch shank diameter suits standard collet chucks and end mill holders common in most CNC setups.

Key Features

• 0.25-inch mill diameter with matching 0.25-inch shank for balanced tool geometry
• 0.375-inch length of cut in a stub-length profile for improved rigidity
• Micrograin solid carbide construction for hardness and wear resistance
• TiCN coating reduces friction and extends tool life in abrasive materials
• 40-degree right-hand spiral flutes promote efficient chip evacuation
• Single-end design; 2.0-inch overall length

Compatibility

Designed as a direct-fit replacement or standard addition to tooling inventories for CNC machining centers using ER collets or end mill holders with a 0.25-inch bore.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank in a clean, properly sized collet or end mill holder and torque to the holder manufacturer's specification. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
