Accupro 12182783 Square End Mill 13/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182783 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. The cutting diameter is 13/64 inches (0.2031 inches), with a 3/8 inch length of cut and a 1/4 inch shank diameter. Overall length is 2 inches, placing it in the stub length category. The AlTiN (aluminum titanium nitride) coating improves heat resistance and tool life in high-speed dry or semi-dry cutting environments. With 4 spiral flutes and a 40-degree helix angle, this end mill is suited for general-purpose profiling, slotting, and light pocketing. It is centercutting, allowing plunge entry into the workpiece.

This end mill is used in CNC machining centers, knee mills, and manual milling machines in job shops, tool rooms, and production environments. The stub length configuration provides added rigidity, reducing deflection in tight-tolerance applications. The right-hand cut and right-hand flute configuration is the industry-standard orientation for conventional and climb milling. The micrograin carbide substrate and AlTiN finish make it a solid choice for cutting hardened steels, stainless steels, cast iron, and other demanding materials where tool wear is a concern.

Key Features

• Solid micrograin carbide construction for wear resistance and edge retention
• AlTiN coating for extended tool life in high-temperature cutting applications
• 4 spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilled pilot holes
• Stub length OAL of 2 inches provides rigidity and reduces deflection
• Right-hand cut, right-hand flute - standard orientation for most milling setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill suitable for standard 1/4 inch collets and end mill holders in CNC and manual milling applications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Ensure the collet or end mill holder is clean and free of chips before seating the shank. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type. Inspect the cutting edges for chipping or wear before each use.
