Accupro 12185208 Square End Mill 13/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12185208 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 13/64-inch (0.2031-inch) mill diameter, a 1/2-inch length of cut, and a 1/4-inch shank diameter with a 2-1/2-inch overall length. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. An AlTiN coating provides thermal and wear resistance for extended tool life in ferrous and hardened materials. With four flutes and centercutting capability, this end mill handles slotting, profiling, and plunge cuts. It is intended for use by machinists and CNC operators in production and toolroom applications.

This end mill is suited for milling ferrous metals, hardened steels, and high-temperature alloys where a hard, heat-resistant coating is required. The stub-length configuration and 0.2031-inch diameter make it appropriate for close-tolerance work in tight geometries. The double-end design allows both ends to be used, which extends tool utility in applicable operations. Right-hand cut and right-hand flute orientation are standard for conventional CNC milling setups.

Key Features

• 13/64-inch (0.2031-inch) mill diameter with a tolerance of +0.000 / -0.002 inches
• AlTiN finish for high-temperature wear resistance in ferrous and hardened materials
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design enables direct plunge entry without pre-drilling
• Double-end configuration for extended tool utility
• Micrograin solid carbide construction for rigidity and edge retention

Compatibility

Designed as a standard replacement or new-install square end mill for CNC machining centers and manual mills using a 1/4-inch collet or chuck system. No specific machine model compatibility was provided by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1/4-inch shank fully and evenly in the collet or tool holder before tightening to the holder manufacturer's specification. Verify runout with a dial indicator before beginning cuts, particularly given the close-tolerance shank diameter tolerance of -0.0001 / -0.0004 inches.
