Accupro 12184622 Ball End Mill 0.2756 in 4 Flute Carbide

Product Description

The ACCUPRO 12184622 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. With a 0.2756 inch (7 mm) mill diameter and a 4-flute configuration, this tool delivers smooth cutting action and improved chip evacuation compared to 2-flute alternatives. The 40-degree helix angle promotes efficient cutting in a wide range of workpiece materials. A micrograin carbide substrate provides the hardness and wear resistance required for demanding milling applications. This tool is used by machinists and CNC operators in job shops, tool rooms, and production environments.

This ball end mill is suited for contour milling, profiling, and 3D surface work on ferrous and non-ferrous metals. The single-end design, right-hand cutting direction, and right-hand flute spiral are standard configurations for conventional CNC machining centers and manual mills. With a 0.748 inch (19 mm) length of cut and a 63 mm overall length, this tool fits applications requiring a compact reach and tight tolerances. The 8 mm shank diameter is compatible with standard collet and end mill holder tooling systems.

Key Features

• 0.2756 inch (7 mm) ball end diameter for precision contouring and radius work
• 4-flute spiral design improves surface finish and material removal rates
• 40-degree helix angle for efficient chip evacuation and reduced cutting forces
• Micrograin solid carbide construction for hardness and extended tool life
• Uncoated finish suitable for use with cutting fluids or in light dry-cutting applications
• Single-end, right-hand cut configuration for standard CNC and manual milling setups

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines equipped with collet chucks 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 stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the machine or toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish.
