Helical Solutions 82395 3/8 in 3 Flute Carbide Square End Mill

Product Description

The HELICAL SOLUTIONS 82395 is a 3-flute solid carbide square end mill designed for high-performance aluminum cutting applications. With a 3/8 inch cutting diameter and a 40-degree helix angle, this tool evacuates chips aggressively while maintaining clean, accurate cuts. The variable index flute spacing reduces harmonic chatter during the cut, improving surface finish and extending tool life. At 2 inches of length of cut and 4 inches overall length, it handles deep-cavity and slotting work where reach matters. Licensed machinists and CNC programmers in job shops and aerospace production environments are the primary users of this tool.

This end mill is built for aluminum and non-ferrous metals where chip packing and heat buildup are the main failure modes. The 40-degree right-hand helical flutes pull chips up and out of the cut efficiently. The bright uncoated finish keeps heat transfer neutral and suits applications where coatings could cause built-up edge on soft alloys. It is equally applicable to full-slot milling, profiling, and pocket interpolation on CNC machining centers and manual mills with appropriate feeds and speeds for aluminum.

Key Features

• Solid carbide construction for rigidity and wear resistance in aluminum cutting
• 3-flute geometry balances chip evacuation with cutting edge strength
• 40-degree right-hand helix angle promotes aggressive chip lift in soft alloys
• Variable index flute spacing reduces chatter and improves surface finish
• Center-cutting design allows plunge entry directly into the workpiece
• Bright uncoated finish suited for aluminum and other non-ferrous materials

Compatibility

Part of the Helical Solutions End Mills for Aluminum series, 3-flute square, 40-degree helix, variable pitch. Designed for use in standard straight-cylindrical 3/8 inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation requires a clean, properly torqued collet or end mill holder sized for a 3/8 inch straight-cylindrical shank. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before mounting or removing the tool. Confirm runout with a dial indicator after seating to maximize tool life and surface finish quality. Follow the machine manufacturer and tooling guidelines for appropriate clamping torque and stick-out length.
