Accupro 12183204 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12183204 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, it delivers consistent cutting performance and edge retention in demanding materials. The 4-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 0.1875 inches in diameter with a 1.125-inch length of cut and a 3-inch overall length, this is an extra-long configuration suited for deeper reach applications. The centercutting design allows plunge milling as well as peripheral cuts. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling setups.

This end mill is used in machine shops and production environments for slotting, profiling, and contouring operations. The extra-long overall length makes it well suited for deep pocket work and extended-reach cuts where a standard-length end mill cannot reach. The uncoated micrograin carbide construction is appropriate for a wide range of ferrous and non-ferrous materials. Licensed machinists and CNC operators working on mills, machining centers, and manual knee mills are the typical users of this tool.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 4-flute spiral geometry with 40-degree helix angle for efficient chip evacuation
• Centercutting design enables both plunge and peripheral milling
• Extra-long 3-inch OAL provides extended reach for deep pocket operations
• Right-hand cut and right-hand flute for standard CNC and manual mill compatibility
• Uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as a standard shank end mill compatible with 3/16-inch collets, ER collet chucks, and end mill holders used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder to the recommended engagement depth, and verify runout with a dial indicator before beginning cuts. Follow the tool manufacturer and machine OEM guidelines for speed and feed selection appropriate to the workpiece material.
