Accupro 12184587 Ball End Mill 0.1575 in 4 Flute Carbide

Product Description

The ACCUPRO 12184587 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.1575-inch (4 mm) mill diameter and a 0.5512-inch (14 mm) length of cut, this tool is built for finish profiling, contouring, and detail work in tight geometries. The TiCN coating provides enhanced surface hardness and lubricity, extending tool life in abrasive cutting conditions. The 4-flute, single-end configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and tool-and-die professionals rely on this end mill for high-accuracy work on CNC machining centers.

This end mill is suited for profiling, slotting, and contouring passes on machined components across job shop, production, and toolroom environments. The 4 mm shank diameter makes it compatible with standard ER and precision collet chuck systems. Its regular length classification and 50 mm overall length allow it to fit within standard tool-length offsets on most vertical and horizontal machining centers. Right-hand cutting and right-hand flute direction conform to conventional CNC spindle setups. The micrograin carbide substrate supports higher feed rates and improved edge retention compared to standard carbide grades.

Key Features

• 0.1575-inch (4 mm) ball end diameter for fine contouring and profiling
• TiCN coating for improved wear resistance and reduced friction in abrasive materials
• 4-flute design with 40-degree helix angle for efficient chip evacuation and surface finish
• Micrograin solid carbide substrate for edge retention and rigidity
• Single-end, right-hand cut with right-hand spiral flute direction
• Regular length at 50 mm overall length with 4 mm shank for standard collet compatibility

Compatibility

Designed as a standard-geometry replacement or addition for solid carbide ball end mill applications requiring a 4 mm shank diameter and ER-style or precision collet chuck toolholding systems.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and the controller is in a safe state before changing tooling. Seat the shank fully into the collet and torque the collet nut to the toolholder manufacturer specification. Verify tool runout with a dial indicator before beginning cuts, as excessive runout accelerates wear on small-diameter carbide end mills.
