Accupro 12181778 Square End Mill 3/16 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 12181778 is a solid carbide square end mill designed for precision milling in metal fabrication and machining applications. It features a 3/16 inch mill diameter, a 1 inch length of cut, and a 2.5 inch overall length, placing it in the extra-long category for reach into deeper pockets or stepped features. The two-flute configuration and spiral flute geometry promote chip evacuation in slotting and profiling operations. An AlTiN coating provides heat resistance and extended tool life when cutting ferrous materials at elevated surface speeds. The micrograin carbide substrate supports tight tolerances and edge integrity under demanding conditions.

This end mill suits CNC machining centers and manual mills in job shop, toolroom, and production environments. Its centercutting capability allows plunge entry directly into the workpiece, making it practical for drilling entry points before side milling. The right-hand cut and right-hand flute orientation are standard for conventional CNC spindle setups. Typical applications include slotting, profiling, and pocketing in steel, stainless steel, cast iron, and similar ferrous alloys where the AlTiN finish performs best.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN coating for heat resistance and extended tool life in ferrous materials
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Two-flute spiral geometry promotes chip evacuation in slotting operations
• Extra-long overall length of 2.5 inches for reach into deeper features
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 3/16 inch collets and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the shank in a clean, properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specification. Inspect the collet bore and shank for contamination before seating the tool. Confirm spindle direction is set to right-hand rotation before engaging the cut.
