Accupro 14797402 Ball End Mill 0.026 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 14797402 is a miniature solid carbide ball end mill designed for precision milling in demanding applications. Built from micrograin carbide and coated with AlTiN (Aluminum Titanium Nitride), it delivers strong heat resistance and extended tool life at elevated cutting speeds. The ball nose geometry produces accurate radius profiles in slots, pockets, and contoured surfaces. With a 0.026-inch cutting diameter and 0.039-inch length of cut, this mill is engineered for fine detail work in hard or abrasive materials. It is a single-end tool with a right-hand cutting and right-hand spiral flute direction.

This end mill is suited for CNC machining centers and high-speed milling applications where tight tolerances and small-feature geometry are required. The miniature series designation indicates it is built for fine-detail work in molds, dies, medical components, and similar precision part production. The 30-degree helix angle promotes smooth chip evacuation while maintaining cutting stability at small diameters. A 1/8-inch shank fits standard collets and toolholders commonly used in benchtop and full-size CNC setups handling miniature tooling.

Key Features

• 0.026-inch ball nose diameter with a mill diameter tolerance of +0.0000 to -0.0010 inches for consistent dimensional accuracy
• AlTiN coating provides high-temperature resistance and reduced friction for dry or semi-dry cutting
• Micrograin solid carbide substrate for rigidity and wear resistance at small diameters
• 2-flute, right-hand spiral design with 30-degree helix angle for effective chip removal
• 1/8-inch shank diameter with a tolerance of -0.0001 to -0.0003 inches for secure collet grip
• Single-end construction in the Miniature series for fine-feature and tight-tolerance work

Compatibility

Designed for use in CNC milling machines and machining centers accepting a 1/8-inch shank collet or toolholder; suitable for milling ferrous and non-ferrous materials where a miniature ball nose profile is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool. Seat the shank fully in a clean, properly sized collet or toolholder and tighten to the manufacturer-specified clamping torque for that holder type. Verify runout with a dial indicator before beginning the cut, as excessive runout will accelerate wear and reduce accuracy at this diameter.
