Accupro 12182867 Square End Mill 23/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182867 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 23/64 inch (0.3594 inch) cutting diameter, a 4-flute spiral geometry with a 40-degree helix angle, and an AlTiN coating that extends tool life in high-heat cutting environments. The stub-length configuration keeps the tool rigid under load. With a right-hand cut and right-hand flute direction, it suits standard vertical and horizontal milling setups. Centercutting capability allows plunge entry into the workpiece. Machinists, toolmakers, and CNC operators in job shops and production environments are the primary users of this end mill.

This end mill is suited for slotting, profiling, and pocketing operations on machining centers and manual mills. The stub length overall profile reduces deflection in short-reach applications. The 40-degree helix promotes efficient chip evacuation and smooth cutting action in a variety of workpiece materials. The micrograin carbide substrate provides a balance of hardness and toughness appropriate for general-purpose and finish milling work.

Key Features

• 23/64 inch cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches for precise fitment
• 4-flute spiral geometry with a 40-degree helix angle for improved chip flow and surface finish
• AlTiN coating for elevated heat resistance and extended tool life in demanding cuts
• Centercutting design allows direct plunge entry without pre-drilling
• Micrograin solid carbide substrate for rigidity and edge retention
• Stub length (2.0 inch OAL) minimizes deflection in short-reach setups

Compatibility

Designed as a standard shank end mill compatible with 3/8 inch collets, ER-style chucks, and milling machine spindles accepting a 3/8 inch straight shank. Verify spindle and holder specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before loading or changing the tool. Seat the shank fully in the collet or tool holder to the recommended engagement depth and torque the retention hardware to the tool holder manufacturer specification. Inspect the cutting edges for chips or damage before each use.
