Accupro 12182477 Square End Mill 17/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182477 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 17/64 inch (0.2656 inch) cutting diameter and four spiral flutes ground to a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action in a wide range of materials. The AlTiN coating provides elevated heat and wear resistance, extending tool life in demanding cutting conditions. Micrograin carbide construction offers a balance of hardness and toughness suited to finish and semi-finish milling passes.

This end mill is built for use in CNC machining centers and manual mills where tight tolerances and consistent surface finishes are required. The centercutting geometry allows plunge entry directly into the workpiece, giving machinists flexibility for slot milling, pocket milling, and profile work. The 5/16 inch shank fits standard collets and end mill holders common in production and job shop environments. Right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling on most setups.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN finish for high heat resistance and extended tool life in ferrous and hardened materials
• 40-degree helix angle promotes aggressive chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without a pre-drilled entry hole
• Four flutes provide a balance of material removal rate and finish quality
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit in close-tolerance work

Compatibility

Designed as a standard square end mill for use in 5/16 inch collets and end mill holders on CNC and manual milling machines. Suitable for ferrous metals, alloy steels, and similar materials where AlTiN coating performance is appropriate.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer torque and runout specifications for the collet or holder system in use. Always power down and lock out the spindle before changing tooling. Inspect the shank and collet bore for chips or damage before seating the tool. Confirm proper stick-out length and runout with a dial indicator before beginning a cut.
