Helical Solutions 48376 Corner Radius End Mill 0.5in 3 Flute

Product Description

The HELICAL SOLUTIONS 48376 is a solid carbide corner radius end mill designed for high-performance material removal in aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The 0.5-inch diameter cutter features a 0.0300-inch corner radius, three flutes, and a 1.0-inch length of cut. A Zplus PVD coating improves lubricity and wear resistance in aluminum applications. Variable pitch geometry reduces harmonic vibration during aggressive cuts. This tool is installed by machinists and CNC tool-and-die professionals operating vertical and horizontal machining centers.

The 48376 is built for both roughing and finishing passes in a single tool, making it well suited to aluminum plate, billet, and extrusion work as well as secondary operations on steel and stainless. The 3.0-inch overall length and straight cylindrical shank pair with high-precision toolholders for maximum runout control. Single-end construction with a centercutting geometry allows plunge entry without a pre-drilled hole. It is part of the H40ALV-3 series, which targets high-speed, high-efficiency milling strategies common in aerospace and precision machining environments.

Key Features

• Zplus PVD coating optimized for aluminum and non-ferrous milling with reduced built-up edge
• Variable pitch flute spacing reduces chatter and allows higher feed rates
• 0.0300-inch corner radius with a tight tolerance of -0.0020 to +0.0020 inch protects corners and extends tool life
• Centercutting design permits direct plunge entry into workpiece material
• Right-hand cut and right-hand helix with high helix angle improves chip evacuation in deep pockets
• Straight cylindrical shank with h6 tolerance for accurate seating in high-precision toolholders

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metals. Secondary workpiece materials 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 machinist following the machine tool manufacturer's toolholder torque and clamping specifications. Verify runout at the tool tip does not exceed the 0.0003-inch TIR maximum before beginning a cut. Ensure the shank is fully seated and free of chips or debris before clamping. Confirm spindle speed, feed rate, and depth of cut are appropriate for the workpiece material before engaging the cut.
