Accupro 12185077 Square End Mill 11/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12185077 is a solid carbide square end mill designed for precision milling in metal, composite, and hard-material applications. With an 11/64 inch (0.1719 inch) cutting diameter, 5/16 inch length of cut, and a 40-degree helix angle, this double-end stub-length tool delivers efficient chip evacuation and smooth cutting action in tight-tolerance work. The micrograin carbide substrate provides the hardness and edge retention needed for demanding cuts. Centercutting geometry allows direct plunge entry. Right-hand cut and right-hand spiral flute configuration is standard for conventional milling setups.

This end mill is suited for machining operations requiring small-diameter precision work, including slotting, profiling, and pocketing in ferrous and non-ferrous materials. The stub-length body minimizes deflection, making it a practical choice for high-speed CNC machining centers and manual mills where rigidity at small diameters is critical. The 3/16 inch shank diameter fits standard ER collets and end mill holders commonly used in production and toolroom environments. The double-end configuration extends tool life by providing two usable cutting ends.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge milling without a pre-drilled entry
• Double-end design provides two cutting ends to extend usable tool life
• Stub-length body minimizes deflection on small-diameter cuts
• Uncoated finish suitable for use with cutting fluids on a wide range of materials

Compatibility

Designed as an OEM-style replacement or direct toolroom substitute for small-diameter square end mills used in standard ER collet chucks, shrink-fit holders, and end mill holders accepting a 3/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth before torquing the retention nut. Do not exceed the tool manufacturer's recommended speeds and feeds for the material and diameter in use.
