Accupro 14796989 Square End Mill 0.009 in 2 Flute Carbide

Product Description

The ACCUPRO 14796989 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.009-inch cutting diameter and a 0.014-inch length of cut, this stub-length tool is built for micro-machining operations where rigidity and accuracy are critical. The micrograin carbide construction provides the hardness and wear resistance required for demanding cuts in ferrous and non-ferrous materials. A 30-degree helix angle and right-hand spiral flutes promote efficient chip evacuation while maintaining a clean cutting edge. Two flutes keep the tool light enough for micro-diameter work without sacrificing strength.

This end mill is suited for CNC machining centers, vertical mills, and precision milling machines used in aerospace, medical device, electronics, and tooling applications. The stub length configuration reduces deflection, making it a reliable choice for shallow pockets, slots, and contour work at very small diameters. The bright, uncoated finish allows it to perform effectively in aluminum, brass, and other non-ferrous alloys, as well as certain steels when proper feeds and speeds are observed.

Key Features

• 0.009-inch cutting diameter with a tight mill diameter tolerance of +0.0000 / -0.0010 inches for repeatable precision
• Micrograin solid carbide construction for improved hardness, rigidity, and edge retention at micro-scale
• 30-degree right-hand helix with spiral flutes for efficient chip flow
• Stub-length design minimizes tool deflection during fine-detail cuts
• Centercutting geometry allows plunge entry into the workpiece
• Single end, bright/uncoated finish suitable for non-ferrous and light ferrous machining

Compatibility

Designed as a standard shank replacement-style end mill fitting tool holders and collets accepting a 0.125-inch (1/8 inch) shank diameter. Verify holder runout and collet condition before use at this diameter class.

Installation Notes

Installation should be performed by a qualified machinist familiar with micro-diameter tooling. Ensure the spindle and tool holder are clean and free of debris before seating the 0.125-inch shank, as any contamination will amplify runout at this diameter. Power down and lock out the machine before changing tooling per standard shop safety procedures. Do not exceed recommended feeds and speeds for the workpiece material, as micro-diameter carbide tools are brittle and prone to breakage under excessive load or vibration.
