Accupro 12184810 Ball End Mill 0.3543 in 4 Flute Carbide

Product Description

The ACCUPRO 12184810 is a single-end ball end mill designed for precision milling of contoured surfaces, 3D profiles, and radius features in ferrous and hardened materials. Constructed from micrograin solid carbide, it offers greater rigidity and wear resistance compared to HSS tooling. The 4-flute geometry with a 40-degree right-hand helix provides efficient chip evacuation and a smooth surface finish. An AlTiN coating extends tool life in high-temperature cutting environments. At 9 millimeters (0.3543 inches) cutting diameter with a 14 millimeter (0.5512 inches) length of cut, this stub-length tool suits tight-tolerance work on CNC machining centers.

This ball end mill is suited for use in job shops, tool and die operations, and production machining environments where close-tolerance 3D contouring is required. The 10 millimeter shank diameter and 70 millimeter overall length make it compatible with standard ER and milling collet systems. Its stub-length profile reduces deflection during aggressive side milling and slotting operations. The AlTiN coating makes it well-suited for dry or minimal-lubricant cutting in alloy steels, stainless steels, and hardened materials up to approximately 65 HRC depending on machining parameters.

Key Features

• Micrograin solid carbide substrate for high rigidity and extended edge life
• AlTiN coating improves heat resistance and tool life in ferrous and hardened materials
• 4-flute, right-hand spiral design promotes smooth finish and efficient chip removal
• 40-degree helix angle reduces cutting forces and vibration on contoured passes
• Stub-length (Length Type: Stub) construction minimizes deflection in tight-clearance setups
• Single-end configuration for standard toolholder use on CNC machining centers

Compatibility

Designed for use with standard 10 millimeter collets and milling toolholders on CNC vertical and horizontal machining centers. Suitable for right-hand spindle rotation.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the toolholder collet bore matches the 10 millimeter shank diameter before mounting. Torque the collet nut to toolholder manufacturer specifications and verify runout with a dial indicator before cutting. Confirm spindle direction is set to right-hand rotation prior to program execution.
