Accupro 12184445 Ball End Mill 0.4375 in 3 Flute Carbide

Product Description

The ACCUPRO 12184445 is a single-end ball end mill engineered for precision milling in metalworking and machining applications. Manufactured from micrograin solid carbide, this tool delivers the rigidity and edge retention required for contour milling, profiling, and 3D surface work. It features a 0.4375 inch (7/16 inch) mill diameter, a 2 inch length of cut (LOC), and a 4 inch overall length. The 40-degree right-hand helix and 3-flute spiral configuration promote efficient chip evacuation while maintaining surface finish quality. The uncoated carbide substrate suits a range of base materials where coating interaction is a concern.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills where long-reach profiling or cavity work is required. The long flute configuration and extended LOC make it appropriate for deeper passes on molds, dies, and complex contoured workpieces. Machinists and tool and die makers working in job shops or production environments will find this tool applicable to steel, aluminum, and similar machinable materials at appropriate feeds and speeds.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• 0.4375 inch mill diameter with matching 7/16 inch shank for direct collet or end mill holder fitment
• 2 inch length of cut supports deeper cavity and profile passes
• 3-flute, right-hand spiral design balances chip clearance with cutting efficiency
• 40-degree helix angle promotes smooth cutting action and reduced vibration
• Uncoated finish suitable for applications where an uncoated substrate is preferred
• Single-end design; no extended reach or chipbreaker

Compatibility

Designed as a standard single-end ball end mill with a 7/16 inch shank, compatible with any ER collet chuck, end mill holder, or shrink-fit holder sized for 7/16 inch or 0.4375 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout requirements. Ensure the spindle and toolholder are free of debris before seating the shank. Confirm proper stick-out and gauge length before starting the spindle. Always verify feed and speed parameters against the workpiece material prior to cutting.
