Accupro 12182051 Square End Mill 7/16 Inch 3 Flute Carbide

Product Description

The ACCUPRO 12182051 is a solid carbide square end mill designed for precision milling in metal and hard material applications. It features a 7/16 inch cutting diameter, a 1 inch length of cut, and a 2-3/4 inch overall length with a matching 7/16 inch shank diameter. The AlTiN coating improves heat resistance and extends tool life in high-speed dry or semi-dry cutting operations. The 3-flute, spiral flute design with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. Micrograin carbide construction provides the rigidity and edge retention required for ferrous and non-ferrous machining. This tool is intended for use by machinists and CNC operators in production and job-shop environments.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous metals, stainless steel, cast iron, and high-temperature alloys where a durable coated carbide tool is required. The centercutting geometry allows direct plunge entry into the workpiece, adding versatility for interpolated bore operations and ramping. Right-hand cut and right-hand flute configuration is standard for conventional CNC machining center spindle rotation. The regular length classification makes it appropriate for general-purpose setups where rigidity is prioritized over extended reach.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• AlTiN coating for high-temperature resistance and extended tool life
• 40-degree helix angle with spiral flute design for efficient chip evacuation
• Centercutting capable — supports plunge entry and ramp operations
• Right-hand cut, right-hand flute — compatible with standard CNC spindle rotation
• Tight diameter tolerances: +0.000/-0.002 inches on mill diameter; -0.0001/-0.0004 inches on shank diameter

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using ER or end mill holders with a 7/16 inch bore. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into a properly sized collet or end mill holder and torque the retention system according to the toolholder manufacturer specifications. Inspect the shank and collet bore for contamination or wear before seating. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.
