Accupro 12184470 Ball End Mill 0.375 in 3 Flute Ticn Carbide

Product Description

The ACCUPRO 12184470 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.375-inch cutting diameter, a 1.75-inch length of cut, and a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action. The TiCN (titanium carbonitride) coating increases surface hardness and reduces friction, extending tool life in abrasive and harder materials. The micrograin carbide substrate provides the toughness and wear resistance required for demanding machining environments. This is a single-end tool with right-hand cutting and right-hand flute direction, suited for CNC machining centers and manual mills operated by machinists and tool-and-die professionals.

This ball end mill is intended for contour milling, profiling, slotting, and 3D surface finishing in shop and production environments. The extra-long configuration, with a 4-inch overall length and a 3/8-inch shank diameter, allows access to deeper pockets and features where standard-length tools cannot reach. The three-flute geometry balances chip clearance with rigidity, making it effective for finishing passes and moderate material removal rates in steel, stainless, cast iron, and hardened alloys.

Key Features

• TiCN coating improves hardness and lubricity for extended tool life in abrasive materials
• Micrograin solid carbide substrate provides rigidity and resistance to chipping
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Extra-long overall length of 4 inches enables deep-pocket and hard-to-reach milling
• Three-flute design balances chip clearance and cutting edge strength
• Single-end, right-hand cut configuration compatible with standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or direct-application ball end mill for CNC machining centers and manual mills using a 3/8-inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the machine spindle is fully stopped and the tool is properly seated and torqued in the collet or end mill holder before beginning a cut. Verify tool projection and reach before engaging the workpiece to avoid deflection or chatter. Inspect the cutting edges for wear or chipping before each use.
