Accupro 12177574 Tapered Ball End Mill Solid Carbide

Product Description

The ACCUPRO 12177574 is a solid carbide tapered ball end mill designed for precision milling of contoured surfaces, angled walls, and complex 3D profiles. With a 1/8-inch small end diameter, a 1-degree taper per side, and a 1/16-inch nose radius, this tool delivers tight-tolerance finishes in die and mold work, aerospace components, and medical part machining. The micrograin carbide construction provides the rigidity and edge retention needed for demanding finish passes. It installs in standard collet chucks and is run by CNC machinists and tool-and-die professionals.

This end mill is suited for finish and semi-finish milling of hardened and difficult-to-machine materials where a fine surface finish and accurate taper angle are required. The 1-inch length of cut allows access into moderate-depth cavities and pockets, while the 3/16-inch shank fits standard collet sizes commonly found in vertical machining centers and CNC mills. The right-hand flute direction and 30-degree helix angle support smooth chip evacuation and reduced chatter during contour passes.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity
• Ball end geometry with 1/16-inch nose radius for smooth contoured surface finishes
• 1-degree taper per side for accurate angled wall milling
• 3 flutes with right-hand spiral and 30-degree helix angle for efficient chip evacuation
• Centercutting capable, allowing plunge entry into workpiece material
• Uncoated finish suitable for use with cutting fluids across a range of workpiece materials

Compatibility

Designed as a direct-fit replacement for standard 3/16-inch shank collet tooling in CNC vertical machining centers and milling machines requiring a 1-degree-per-side tapered ball end mill configuration.

Installation Notes

This tool is installed by CNC machinists or tool-and-die technicians using a collet chuck or end mill holder sized for a 3/16-inch shank. The machine spindle must be powered down and locked out before tool changes. Verify runout with a dial indicator after seating the tool to confirm proper holding and avoid premature edge wear. Follow machine tool manufacturer guidelines for feeds, speeds, and coolant application when setting up this cutter.
