Accupro 12185028 Square End Mill 3/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12185028 is a double-end square end mill designed for precision milling operations in metalworking and machining environments. Built from solid carbide micrograin substrate, it delivers the hardness and edge retention needed for demanding cuts in ferrous and non-ferrous materials. The AlTiN coating provides thermal resistance and reduces friction at high cutting speeds. With a 3/16 inch cutting diameter, 2-flute spiral geometry, and a 40-degree helix angle, this tool is optimized for chip evacuation and surface finish quality. It is centercutting, allowing plunge entry into the workpiece. Machinists and toolroom professionals select this end mill for finish milling, slotting, and light profiling operations on CNC mills and manual knee mills.

This end mill suits production and toolroom applications in industries including aerospace, automotive, and general metalworking. The 3/8 inch shank diameter fits standard ER collet chucks and end mill holders commonly found on vertical machining centers and manual mills. The double-end design provides a second usable cutting end, extending tool life per unit. The regular-length configuration and 1/2 inch length of cut make it appropriate for shallow-to-medium depth slots and profiles where rigidity is a priority.

Key Features

• Solid carbide micrograin construction for superior hardness and wear resistance
• AlTiN coating for high-temperature performance and extended tool life
• 40-degree helix angle promotes efficient chip evacuation and smooth surface finish
• Centercutting design enables direct plunge milling without pre-drilling
• Double-end configuration provides two cutting ends per tool
• Right-hand cut, right-hand flute spiral geometry for standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard 3/8 inch collet chucks and end mill holders on vertical CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out or powered-down state per shop safety procedures. Ensure the collet or holder is clean and within specified runout tolerance before seating the shank. Do not exceed the tool manufacturer's recommended speeds and feeds for the material being cut. Inspect both cutting ends before use and rotate to the second end only when the first shows measurable wear.
