Accupro 12183762 Square End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12183762 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. With a 0.375 inch mill diameter and a 3 inch length of cut, this tool delivers extended reach capability suited for deep-slot, side-wall, and profiling work. The 40-degree helix angle combined with the AlTiN (aluminum titanium nitride) coating enhances heat resistance and tool life when cutting ferrous and hardened materials. At 6 inches overall length, it is classified as an extra-long end mill. It is centercutting, allowing plunge entry. Setup and operation require a CNC machining center or manual milling machine with a properly sized collet or tool holder.

This end mill is built for shops working in steel, stainless steel, cast iron, and similar hard materials where coating performance and rigidity matter. The micrograin carbide substrate supports tight tolerances and consistent edge integrity across longer runs. Its extra-long 6 inch overall length suits applications where standard-length tools cannot reach the required depth, such as deep-pocket milling, tall-wall profiling, and fixture-clearance situations. It is sold and packaged as a single unit.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN coating for elevated heat resistance and extended tool life in ferrous materials
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Extra-long 6 inch OAL provides reach for deep-pocket and tall-wall applications
• Right-hand cut, right-hand spiral flute configuration — standard for CNC and manual mills

Compatibility

Designed as a standard 3/8 inch shank square end mill compatible with 3/8 inch collets, end mill holders, or shrink-fit tooling on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the machine spindle before loading or changing tooling. Seat the shank fully into the collet or holder to the recommended gauge depth to minimize runout and prevent pull-out under load. Verify tool runout with a dial indicator before cutting, particularly on long-reach tools where deflection is a concern.
