Accupro 12185078 Square End Mill 11/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12185078 is a double-end, square-profile solid carbide end mill designed for precision milling in metalworking and machining operations. The cutting diameter measures 11/64 inches (0.1719 inches) with a 3/16-inch (0.1875 inches) shank diameter and a 2-inch overall length. The micrograin carbide substrate supports a TiCN (Titanium Carbonitride) coating that increases surface hardness and wear resistance. With a 40-degree helix angle and spiral flute geometry, this tool promotes efficient chip evacuation during slotting, profiling, and plunge cuts.

This stub-length end mill is suited for light-material removal and close-tolerance work in ferrous and non-ferrous metals, plastics, and composites. The centercutting design allows direct plunge entry without pre-drilling. The double-end configuration provides two usable cutting ends, extending tool service life in production environments. A licensed machinist or CNC operator typically installs and runs this tool in a vertical machining center, CNC mill, or manual knee mill using a collet or end mill holder matched to the 3/16-inch shank.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance at elevated cutting speeds
• TiCN finish improves surface hardness and reduces built-up edge on ferrous materials
• 40-degree helix angle with spiral flutes for effective chip evacuation in slotting and profiling
• Centercutting geometry allows direct plunge milling without a pilot hole
• Double-end design provides two cutting ends per tool, lowering cost-per-edge in production use
• Stub-length profile (5/16-inch length of cut) maximizes rigidity and minimizes deflection in tight setups

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 3/16-inch collet or end mill holder. Suitable for right-hand spindle rotation. No specific compatible machine models were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the 3/16-inch shank in a properly sized collet or end mill holder, and confirm runout before initiating a cut. Power down and lock out the machine spindle before changing tooling. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material.
