Helical Solutions 87065 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 87065 is a 3-flute solid carbide square end mill engineered for high-performance aluminum milling. Built with a 45-degree helix angle and Zplus coating, this tool is designed to evacuate chips aggressively and reduce built-up edge when cutting aluminum alloys. The 3/16 inch cutting diameter and 1-3/8 inch length of cut make it well suited for slotting, pocketing, and profiling passes in tight geometries. Machinists and CNC operators working with aluminum components will find this end mill a reliable choice where surface finish and tool life both matter.

This end mill is intended for aluminum milling applications in job shop, production, and prototype machining environments. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. The single-end, straight-cylindrical shank allows direct collet or end mill holder mounting. It is suited for light-duty aluminum roughing and finishing passes where a small-diameter tool is required, such as thin-wall features, narrow slots, or detailed profile work.

Key Features

• 45-degree helix angle promotes aggressive chip evacuation in aluminum
• Zplus coating reduces built-up edge and improves tool life in non-ferrous materials
• 3-flute geometry balances material removal rate with chip clearance
• Centercutting design allows plunge entry
• Solid carbide construction delivers rigidity and wear resistance
• Straight-cylindrical shank for standard collet chuck or end mill holder mounting

Compatibility

Part of the Helical Solutions End Mills for Aluminum - 3 Flute - Square - 45 Degree Helix series. Designed for use in CNC milling machines with standard 3/16 inch collet or end mill holder setups for aluminum alloy cutting applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or collet is properly released before inserting or removing the end mill. Seat the shank fully and evenly in the holder to the recommended gauge length before tightening to prevent runout. Verify feeds, speeds, and depth of cut against the manufacturer cutting data for aluminum before beginning a new operation.
