Accupro 12185178 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185178 is a double-end, four-flute square end mill ground from solid micrograin carbide and coated with AlTiN for extended tool life in abrasive and hard materials. The cutter measures 0.125 inches in diameter with a 0.25-inch length of cut and a 1.5-inch overall length. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Centercutting geometry allows plunge entry, making it suitable for slot milling, profiling, and pocket work. This tool is intended for use by machinists and tool-and-die professionals in CNC machining centers and manual mills.

The 12185178 is suited to stub-length applications where rigidity is a priority and minimal overhang is required. Its right-hand cut, right-hand spiral flute configuration is standard for conventional and climb milling on CNC equipment. The AlTiN coating supports dry or minimal-lubrication cutting strategies, particularly in steels, stainless, and titanium alloys. The double-end design provides two usable cutting ends, extending the service interval before replacement is required.

Key Features

• Solid micrograin carbide construction for wear resistance and edge integrity
• AlTiN coating for thermal resistance and extended tool life in hard and abrasive materials
• 40-degree helix angle for efficient chip flow and reduced cutting forces
• Centercutting geometry enables direct plunge entry without pre-drilling
• Double-end design provides two cutting ends per tool
• Stub length classification maximizes rigidity in tight-clearance setups

Compatibility

Designed as a standard 1/8-inch shank square end mill compatible with collet chucks, end mill holders, and tool holders accepting 0.125-inch shank diameters on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify collet or holder runout is within acceptable limits before use, as excessive runout accelerates edge wear on small-diameter carbide tools. Do not exceed the recommended depth of cut or feed rate for the workpiece material and tool diameter.
