Accupro 12179704 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12179704 is a solid carbide square end mill designed for precision metal removal in milling applications. It measures 3/16 inches in diameter with a 3/8-inch length of cut and a 2-inch overall length. The three-flute, spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting performance. The ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in ferrous and non-ferrous materials. Stub length geometry keeps deflection low, making this end mill a reliable choice for machinists and tool-and-die professionals working in tight setups.

This end mill suits general-purpose milling on CNC machining centers and manual mills. Its centercutting capability allows plunge cutting as well as peripheral milling, giving machinists flexibility in slotting, profiling, and pocket operations. The right-hand cut and right-hand flute orientation follow standard conventions for the majority of vertical and horizontal mill setups. The micrograin carbide substrate supports use in a wide range of materials including aluminum, steel, stainless, and plastics at appropriate feeds and speeds.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN finish for improved heat resistance and extended tool life
• 40-degree helix angle with spiral flutes for effective chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Stub length geometry minimizes deflection in shallow-reach applications
• Right-hand cut and right-hand flute for standard mill spindle compatibility

Compatibility

Designed as a standard stub-length square end mill compatible with 3/16-inch collets, ER collet chucks, and end mill holders on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully in the collet or tool holder to the recommended engagement depth before tightening to avoid runout. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify feeds, speeds, and depth of cut are appropriate for the workpiece material before starting the cut.
