Accupro 12184784 Ball End Mill 0.2756 in 4 Flute Carbide

Product Description

The ACCUPRO 12184784 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.2756 inch (7 mm) cutting diameter and a 4-flute configuration, this tool delivers smooth chip evacuation and excellent surface finish on ferrous and non-ferrous materials. The 40-degree helix angle promotes aggressive cutting action while reducing chatter. Built from micrograin solid carbide, it maintains edge integrity under demanding cutting conditions. The bright uncoated finish suits a wide range of general-purpose milling tasks where specialized coatings are not required. Licensed machinists and CNC operators are the primary users of this tool.

This ball end mill is suited for contour milling, profiling, slotting, and 3D surface work on machining centers and CNC mills. The stub-length profile and single-end design make it a practical choice for rigid setups with minimal overhang. The 8 mm shank diameter fits standard collets and tool holders commonly found in both vertical and horizontal machining centers. It is appropriate for light to medium-duty cuts on steel, aluminum, cast iron, and similar materials where a fine radius tip is required.

Key Features

• 0.2756 inch (7 mm) ball nose cutting diameter for precise radius profiling
• 4-flute spiral design for efficient chip removal and improved surface finish
• 40-degree right-hand helix angle reduces cutting forces and chatter
• Micrograin solid carbide construction for extended tool life and edge retention
• Bright uncoated finish suitable for general-purpose milling applications
• Stub-length, single-end configuration promotes rigidity in tight setups

Compatibility

Designed as an OEM-style replacement and standard-fit tool for CNC machining centers and manual mills equipped with collet or end mill holders accepting an 8 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or tool holder and torque the retention mechanism per the machine tool manufacturer specifications. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator before beginning a production run.
