Accupro 14799513 Corner Radius End Mill 0.025in 4 Flute

Product Description

The ACCUPRO 14799513 is a miniature solid carbide corner radius end mill designed for precision milling in tight tolerances and fine-detail work. It features a 0.025 inch cutting diameter with a 0.005 inch corner radius, four right-hand spiral flutes, and an AlTiN coating for extended tool life in harder materials. The 30-degree helix angle supports chip evacuation in shallow, high-speed passes. At 1.5 inches overall length with a 0.075 inch length of cut, this is a single-end, centercutting tool built for CNC machinists running miniature and micro-machining operations in ferrous and non-ferrous materials.

This end mill is suited for precision CNC milling applications where fine corner geometry is required, such as mold and die work, medical component machining, and electronics fixture work. The miniature series designation indicates it is built for small-diameter, close-tolerance jobs. The centercutting geometry allows plunge entry, giving machinists flexibility in toolpath programming. The AlTiN coating handles elevated cutting temperatures common in steel and stainless alloys, reducing wear at high spindle speeds.

Key Features

• 0.005 inch corner radius for fine edge geometry and reduced stress concentration at corners
• AlTiN coating provides heat resistance for dry or semi-dry cutting in ferrous alloys
• Solid micrograin carbide substrate supports rigidity at small diameters
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute spiral for standard CNC spindle compatibility
• 1/8 inch shank diameter fits standard ER and collet toolholders common in CNC machining centers

Compatibility

Designed as an OEM-style miniature end mill for use in CNC machining centers and milling machines equipped with 1/8 inch collet or ER-style toolholding systems.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a safe, locked-out state per shop safety protocols. Secure the 1/8 inch shank in a properly sized, clean collet or toolholder and torque the retention nut to the toolholder specification. At this diameter, runout control is critical — inspect the collet and holder for wear before seating the tool. Handle micrograin carbide tools with care to avoid chipping the flutes or corner radius during setup.
