Accupro 12184583 Ball End Mill 0.1563 in 4 Flute Carbide

Product Description

The ACCUPRO 12184583 is a single-end ball end mill designed for precise contour milling, profiling, and 3D surface work in CNC machining centers and manual mills. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for harder workpiece materials and demanding cutting conditions. The mill measures 0.1563 inches in diameter with a 0.5-inch length of cut and a 2-inch overall length. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Four flutes provide a good balance of chip clearance and surface finish. This tool is installed and operated by machinists and CNC programmers in job shops, production facilities, and tool rooms.

This ball end mill is suited for small-feature profiling, cavity work, and finishing passes in ferrous and non-ferrous materials. Its micrograin carbide substrate handles the cutting forces generated in steel, stainless, aluminum, and similar materials. The uncoated finish makes it a versatile choice when a specific coating is not required by the application or when regrinding after use is planned. The 3/16-inch shank diameter fits standard collet systems used on most vertical machining centers and CNC routers. The single-end configuration is standard for precision milling work where tool runout and reach must be tightly controlled.

Key Features

• Micrograin solid carbide construction for edge retention and resistance to deflection
• 0.1563-inch ball diameter with tight tolerance of +0.000 to -0.002 inches for accurate profiling
• 40-degree right-hand helix for efficient chip flow and reduced cutting heat
• 4-flute spiral geometry balances chip clearance with surface finish quality
• Uncoated finish allows use across a broad range of materials and supports regrinding
• Single-end design maintains concentricity and minimizes runout in precision setups

Compatibility

Designed as an OEM-style replacement and standard production end mill for use in collet-style toolholding systems accepting a 3/16-inch shank diameter on vertical machining centers, CNC mills, and compatible manual mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Power down and lock out the spindle before installing or removing the tool. Seat the shank fully into the collet to the recommended insertion depth and torque the collet nut to the toolholder specification. Inspect the cutting edges and shank for chips or damage before each use, and verify runout with a dial indicator when tolerance-critical work is planned.
