Accupro 12185372 Ball End Mill 9/32 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185372 is a solid carbide ball end mill engineered for precision milling in ferrous and hardened materials. With a 9/32-inch (0.2813-inch) cutting diameter and a 4-flute spiral design, it delivers excellent surface finish and material removal in finishing and semi-finishing operations. The 40-degree helix angle reduces cutting forces and promotes chip evacuation. An AlTiN coating adds thermal resistance and hardness, making this tool well-suited for dry or high-speed machining applications. The double-end configuration maximizes tool life before replacement. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is intended for use in CNC machining centers, knee mills, and high-speed spindles where tight tolerances and fine surface finishes are required. Its stub-length classification and 5/16-inch shank diameter make it appropriate for setups where rigidity and reduced overhang are priorities. The right-hand cutting and right-hand flute direction are standard for conventional milling setups. Applications include contouring, profiling, and slotting in tool steel, stainless steel, cast iron, and similar alloys.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides high thermal resistance for dry and high-speed cutting
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Double-end design doubles usable life before tool discard
• 4-flute spiral geometry delivers improved surface finish in finishing passes
• Stub-length classification with 1/2-inch length of cut for maximum rigidity

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 5/16-inch round shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into a collet or end mill holder to the recommended engagement depth before tightening. Confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut. Inspect the tool for chipping or wear before each use and do not run a damaged end mill.
