Accupro 14797528 Corner Radius End Mill 0.03 in 2 Flute

Product Description

The ACCUPRO 14797528 is a miniature solid carbide corner radius end mill designed for precision milling operations requiring tight tolerances and small-feature detail work. The cutting diameter measures 0.03 inches with a 0.01 inch corner radius, producing a controlled radius at the base of the cut rather than a sharp corner. The 2-flute, single-end geometry with a 30-degree helix angle supports chip evacuation in confined cuts. At 1.5 inches overall length with a 0.09 inch length of cut, this tool is built for micro-scale milling where rigidity and dimensional accuracy are critical. The bright, uncoated finish suits ferrous and non-ferrous materials where coating adhesion or heat buildup is not a primary concern.

This end mill is suited for CNC machining centers, high-speed spindles, and precision manual mills working on small components in tool and die, medical device, electronics, and aerospace applications. The miniature series designation indicates it is intended for micro-feature work, including small slots, pockets, and contour passes on hardened or soft materials where a standard-size tool cannot reach. The centercutting capability allows plunge entry directly into material without a pre-drilled pilot hole.

Key Features

• 0.03 inch cutting diameter with 0.01 inch corner radius for micro-feature milling
• Solid carbide micrograin construction for rigidity and wear resistance in small-diameter tooling
• 2-flute, right-hand cut, right-hand spiral geometry with 30-degree helix angle
• Centercutting design allows direct plunge entry
• Single-end tool with 1/8 inch shank diameter for standard collet compatibility
• Bright, uncoated finish suitable for a wide range of workpiece materials

Compatibility

Designed for use in CNC machining centers and manual mills with 1/8 inch collets or collet chucks accepting standard miniature-series solid carbide end mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Use a properly sized collet or tool holder matching the 1/8 inch shank diameter to ensure concentricity and minimize runout. At this diameter, even slight runout will reduce tool life and dimensional accuracy significantly. Inspect the collet and collet nut for wear or debris before seating the tool.
