Accupro 14797199 Square End Mill 3/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14797199 is a solid carbide square end mill designed for precision metal removal in tight-tolerance machining applications. Built from micrograin carbide and finished with an AlTiN (aluminum titanium nitride) coating, it delivers strong heat and wear resistance at elevated cutting speeds. The mill features a 3/64 inch (0.0469 inch decimal) cutting diameter, a 0.07 inch length of cut, and a 30-degree right-hand spiral helix. Three flutes provide efficient chip evacuation while maintaining rigidity at this small diameter. It is a single-end, centercutting tool suited for end milling, profiling, and slot work in ferrous and hardened materials.

This end mill is sized for small-feature work in CNC machining centers and manual knee mills where access to tight geometries is required. The extended reach configuration, with a 0.375 inch reach length and a 0.480 inch neck length, allows the tool to reach into pockets and recesses without interference from the shank. The 1/8 inch shank diameter is compatible with standard collet systems commonly found in both production and tool-room environments. It is typically selected by machinists and CNC operators working in aerospace, mold and die, and precision parts manufacturing.

Key Features

• AlTiN coating provides thermal resistance and extended tool life in dry or high-speed cutting conditions
• Micrograin solid carbide substrate delivers hardness and edge stability at 3/64 inch diameter
• 30-degree right-hand helix promotes smooth chip flow and reduced cutting forces
• Centercutting geometry allows plunge entry into workpiece material
• Extended reach design accesses deep pockets and narrow recesses
• Single-end configuration with right-hand cutting direction for standard spindle use

Compatibility

Designed as a standard single-end square carbide end mill compatible with 1/8 inch collet holders and tool holders used in CNC machining centers and manual mills accepting that shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and machine is powered down before changing tooling. Seat the shank fully into the collet and torque the collet nut to the tool holder specification. Verify runout with a dial indicator before beginning a production cut, particularly given the small diameter and extended reach of this tool.
