Helical Solutions 48425 Square End Mill 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 48425 is a 3-flute solid carbide square end mill designed for high-performance milling in aluminum and non-ferrous materials. With a 0.5-inch mill diameter and a 1.625-inch length of cut, it delivers the reach needed for slotting, profiling, and peripheral milling operations. The 40-degree helix angle promotes efficient chip evacuation in gummy materials, while the variable pitch flute spacing reduces harmonic vibration and chatter during aggressive cuts. This tool is built for machinists and CNC operators working in production and job-shop environments where surface finish and tool life in aluminum are priorities.

This end mill is suited for use on CNC machining centers and manual mills where aluminum, copper, brass, and other non-ferrous workpieces are common. The single-end, right-hand cut configuration with a straight shank fits standard ER and side-lock toolholders with a 0.5-inch bore. The bright, uncoated finish is well-matched to aluminum applications where coatings can cause built-up edge. Center-cutting capability allows for plunge operations in addition to lateral milling.

Key Features

• 40-degree helix angle optimized for aluminum and non-ferrous chip evacuation
• Variable pitch (variable index) flute spacing reduces chatter and vibration
• Center-cutting geometry enables direct plunge entry
• Solid carbide construction for rigidity and wear resistance
• Bright, uncoated finish prevents material adhesion in aluminum
• Right-hand cut and right-hand flute direction for standard spindle use

Compatibility

Designed for use in aluminum and non-ferrous materials (Primary Workpiece Material Code: N) with standard 0.5-inch straight-shank toolholders. Part of the HELICAL SOLUTIONS End Mills for Aluminum - 3 Flute - Square - 40 Degree Helix - Variable Pitch series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or drawbar is secured before inserting or removing the tool. Use a torque wrench and the toolholder manufacturer's recommended procedure when clamping the shank. Verify runout with a dial indicator after seating to maximize tool life and part accuracy.
