Accupro 12177253 Ball End Mill 0.1181 in 2 Flute Carbide

Product Description

The ACCUPRO 12177253 is a solid carbide ball end mill designed for precision milling operations requiring extended reach into deep cavities, pockets, and contoured surfaces. Built from micrograin carbide, this single-end tool features a 0.1181-inch (3.00 mm) cutting diameter with a 2-flute, right-hand spiral configuration and a 40-degree helix angle. The extended reach geometry — 1.4960 inches of reach length with a reduced neck diameter of 0.1130 inches — allows access to features that standard-length end mills cannot reach. The uncoated finish makes it suitable for use across a range of workpiece materials where coating is not required or where re-sharpening is anticipated.

This end mill is used in CNC machining centers and manual mills for profiling, slotting, and finishing passes on complex 3D geometries. The long-length classification and extended reach make it well suited for die and mold work, aerospace component machining, and medical device part production where deep-reach access to tight features is needed. It is installed and operated by machinists and CNC programmers working in job shops, production environments, and toolroom settings.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in precision applications
• 40-degree right-hand helix promotes efficient chip evacuation and smooth cutting action
• Extended reach with 1.4960-inch reach length and 0.1130-inch reduced neck diameter for deep-cavity access
• 2-flute design provides clearance for chip removal in tighter geometries
• Single-end configuration with right-hand cutting direction for standard CNC spindle use
• Uncoated finish allows direct use or facilitates re-sharpening and recoating

Compatibility

Designed as an OEM-style solid carbide ball end mill compatible with standard CNC machining center tool holders and collets accepting a 6 mm shank diameter.

Installation Notes

This tool is installed by qualified machinists in CNC machining centers or manual milling machines using a collet or end mill holder sized for a 6 mm shank. Ensure the spindle and tool holder are clean and free of runout before seating the shank. Confirm tool projection and reach clearance against the workpiece setup before initiating a cutting pass. Follow machine manufacturer guidelines and shop safety procedures when setting tool offsets and running proving passes.
