Accupro 314086 Square End Mill 3/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 314086 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. The 3/4 inch diameter cutting head features 2 spiral flutes with a 45-degree helix angle and a ZrN (zirconium nitride) coating that improves surface hardness and heat resistance. With a 1 inch length of cut, 2-1/2 inch extended reach, and 5 inch overall length, this end mill handles deep-pocket and shoulder milling applications where rigidity and tool life are critical. The micrograin carbide substrate provides uniform grain structure for consistent edge sharpness. This tool is installed by machinists and CNC operators in job shop and production environments.

The 314086 is suited for milling operations in CNC machining centers and manual knee mills requiring a right-hand cut, right-hand flute configuration. The centercutting geometry allows plunge entry directly into the workpiece, eliminating the need for a pre-drilled starting hole in many applications. The 3/4 inch shank diameter seats in standard ER collet chucks, end mill holders, and Weldon-style tool holders common in production shops. Typical applications include slot milling, peripheral milling, and step milling in steel, stainless, and aluminum alloys.

Key Features

• Solid micrograin carbide construction for improved edge retention over high-speed steel
• ZrN coating increases surface hardness and reduces heat buildup at the cutting edge
• 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge entry without a pilot hole
• Extended reach of 2-1/2 inches accommodates deep cavity and tall-wall milling
• Right-hand cut and right-hand spiral flute configuration for standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style solid carbide end mill compatible with standard 3/4 inch end mill holders, ER collet chucks, and Weldon-style holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into the tool holder and torque the retention screw or collet nut to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on carbide tooling.
