Accupro 12180943 Tapered Ball End Mill 1/16 in Carbide

Product Description

The ACCUPRO 12180943 is a tapered ball end mill designed for precision milling operations where controlled taper geometry and a ball-nose profile are required. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers extended tool life in abrasive and high-temperature cutting environments. The 2-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation in tight pockets and contoured surfaces. The small end diameter measures 0.0625 inches with a nose radius of 0.030 inches, making it well suited for fine detail work and finishing passes in hardened or difficult-to-machine materials.

This end mill is used in CNC machining centers for contouring, profiling, and finishing of mold cavities, die work, and intricate 3D geometry. The tapered form at 5 degrees per side allows clean access to angled walls and drafted features without tool interference. With a 0.0625-inch length of cut and a 4-inch overall length on a 1/4-inch shank, it fits standard toolholders and reaches into deep setups while maintaining rigidity. Machinists and tool-and-die professionals running aluminum, stainless, titanium, and hardened steel are the primary users of this tool.

Key Features

• Micrograin solid carbide construction for wear resistance and dimensional stability
• AlTiN coating extends tool life in high-heat and abrasive cutting conditions
• 5-degree taper per side suits drafted walls and angled cavity features
• Ball end profile with 0.030-inch nose radius enables fine 3D contour finishing
• 2-flute right-hand spiral with 30-degree helix promotes chip clearance in narrow cuts
• Centercutting capable, allowing plunge entry into workpiece material

Compatibility

Designed as an OEM-style replacement or direct-use tapered ball end mill for CNC machining centers accepting a 1/4-inch round shank toolholder.

Installation Notes

Installation is performed by qualified machinists following standard CNC tooling setup procedures. Secure the 1/4-inch shank in a collet or end mill holder to the manufacturer-specified runout tolerance before cutting. Verify spindle speed, feed rate, and depth of cut against the material being machined before initiating any program. Inspect the cutting edges and coating condition before each use; do not run a chipped or worn tool.
