Accupro 12185117 Square End Mill 5/32 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12185117 is a solid carbide square end mill designed for precise material removal in ferrous and non-ferrous machining applications. Built from micrograin carbide with a TiCN finish, this double-end tool delivers extended tool life and resistance to wear in demanding cutting environments. It features a 5/32 inch (0.1563 inch) mill diameter, a 7/16 inch length of cut, and a 40-degree helix angle with spiral flutes. The centercutting geometry allows plunge entry as well as peripheral and slot milling. Installed by machinists and toolroom professionals, this end mill fits standard CNC machining centers and manual mills equipped with the appropriate collet or chuck.

This end mill is suited for precision milling operations in job shops, production facilities, and toolroom environments. The 3/8 inch shank diameter and 3 inch overall length make it compatible with common ER collet systems and end mill holders. The double-end configuration maximizes value in applications where both ends can be used before the tool is retired. Right-hand cut and right-hand flute orientation are standard for the majority of vertical machining center setups. Typical applications include slotting, profiling, and light contouring in steel, stainless, aluminum, and similar materials.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating improves surface hardness and reduces friction during cutting
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Double-end configuration extends usable tool life
• Right-hand cut and right-hand flute for standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or direct-fit tool for standard machining setups requiring a 3/8 inch shank, 5/32 inch diameter square end mill in a regular-length configuration.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized ER collet or end mill holder to achieve the specified shank diameter tolerance. Verify runout with a dial indicator after seating to maintain dimensional accuracy during cutting operations.
