Accupro 12184355 Ball End Mill 0.2813 in 3 Flute Carbide

Product Description

The ACCUPRO 12184355 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hard material applications. With a 0.2813-inch (9/32-inch) mill diameter and three spiral flutes, this single-end tool delivers efficient chip evacuation and smooth cutting action. The 40-degree helix angle reduces cutting forces and promotes surface finish quality. Micrograin carbide construction provides the hardness and wear resistance needed for demanding machining environments. This tool is installed and used by machinists and CNC operators working in job shops, production facilities, and tool rooms.

This ball end mill is suited for contour milling, slotting, profiling, and 3D surface work on a range of workpiece materials. The 0.75-inch length of cut accommodates moderate-depth passes, while the 5/16-inch shank diameter fits standard collet and end mill holder tooling. The 2.5-inch overall length keeps the tool rigid and minimizes deflection during cutting. Right-hand cutting and right-hand flute direction make this a standard-orientation tool compatible with conventional CNC machining centers and manual knee mills.

Key Features

• Micrograin solid carbide construction for extended tool life in hard and abrasive materials
• 40-degree helix angle promotes chip flow and reduces cutting pressure
• Three spiral flutes balance chip clearance with cutting edge strength
• Uncoated finish suitable for use with cutting fluids across a broad material range
• Single-end design with 5/16-inch shank for standard collet compatibility
• Right-hand cut and right-hand flute direction for conventional machining center use

Compatibility

Designed as a standard single-end ball end mill with a 5/16-inch shank diameter, compatible with collet chucks and end mill holders sized for 5/16-inch tooling on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized collet or end mill holder torqued to the equipment manufacturer specification before operation. Verify runout with a dial indicator after seating the tool. Select appropriate cutting parameters based on workpiece material and do not exceed the rated length of cut for the depth of engagement.
