Accupro 316102 3/4 Inch 5 Flute Solid Carbide Square End Mill

Product Description

The ACCUPRO 316102 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous metals, alloys, and hardened materials. It features a 3/4-inch cutting diameter, a 1-inch length of cut, and a 4-inch overall length. The five-flute configuration with a 37-degree spiral helix delivers efficient chip evacuation and a smooth surface finish at higher feed rates. The ZrN (zirconium nitride) coating provides elevated hardness and heat resistance, extending tool life in demanding cutting environments. This tool is sold individually and weighs 0.8 pounds.

This end mill is suited for general-purpose and high-productivity milling applications on CNC machining centers and manual mills. The centercutting geometry allows direct plunge entry into the workpiece, making it effective for slot milling, profile milling, and pocket work. The right-hand cut and right-hand spiral flute are standard for conventional spindle configurations. The micrograin carbide substrate supports tight tolerances and consistent performance across production runs in aerospace, die and mold, and general precision machining environments.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating improves surface hardness and thermal protection during high-speed cutting
• Five flutes with 37-degree helix angle for efficient chip flow and reduced cutting forces
• Centercutting design enables direct plunge milling without a pre-drilled entry hole
• Right-hand cut and right-hand flute for standard CNC and manual spindle compatibility
• Mill diameter tolerance of +0.000 / -0.002 inches and shank diameter tolerance of +0.0001 / -0.0004 inches for precise fitment

Compatibility

Designed for use in standard 3/4-inch tool holders, collets, and end mill adapters on CNC machining centers and conventional milling machines accepting a 3/4-inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before installing or removing the end mill. Confirm proper seating depth in the collet or tool holder and verify runout with a dial indicator before beginning a cut. Do not exceed the manufacturer-recommended speeds and feeds for the workpiece material and coating type.
