Helical Solutions 48265 Corner Radius End Mill 3/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 48265 is a solid carbide, single-end corner radius end mill designed for high-efficiency material removal in aluminum and non-ferrous metals. It features a 3/8-inch mill diameter, a 1-inch length of cut, and a corner radius of 0.015 inches. The 3-flute, variable-pitch geometry reduces chatter and harmonics during aggressive cuts, making it well-suited for both roughing and finishing operations in a single tool. Overall length is 2.5 inches with a 3/8-inch straight cylindrical shank. The uncoated bright finish is optimized for aluminum, where coatings can cause built-up edge issues. Installed in high-precision toolholders, this end mill holds a maximum TIR of 0.0003 inches.

This end mill is built for CNC milling applications in aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. It is suited to both roughing and finishing passes in production shops, tool rooms, and job shops running high-speed aluminum programs. The centercutting design allows plunge entry, adding flexibility to complex part programs. It belongs to the H40ALV-3 series, a high-helix, variable-pitch platform engineered specifically for aluminum machining performance.

Key Features

• 3-flute variable-pitch design reduces vibration and chatter during deep cuts
• Solid carbide construction provides rigidity and wear resistance
• Corner radius of 0.015 inches strengthens the cutting edge and reduces corner chipping
• Centercutting geometry allows direct plunge entry into the workpiece
• Uncoated bright finish optimized for aluminum and non-ferrous materials
• High helix angle promotes efficient chip evacuation in aluminum
• Right-hand cut and right-hand flute spiral for standard CNC spindle compatibility

Compatibility

Designed for use with high-precision toolholders. Primary material application is aluminum and non-ferrous metals; secondary applications include steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Part of the HELICAL SOLUTIONS H40ALV-3 series.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool change procedure follows the machine tool manufacturer guidelines before mounting or removing the end mill. Use a high-precision collet or hydraulic toolholder to stay within the 0.0003-inch maximum TIR specification. Confirm correct runout after tool installation before beginning any cutting operation.
