Helical Solutions 87061 Square End Mill 1/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 87061 is a 3-flute solid carbide square end mill designed for high-performance milling in aluminum and non-ferrous materials. With a 1/8 inch cutting diameter, a 1 inch length of cut, and a 45-degree helix angle, this tool promotes efficient chip evacuation and reduces built-up edge — two critical factors when machining soft, gummy materials like aluminum. The Zplus coating adds lubricity and heat resistance at the cutting edge. This is a single-end, right-hand cutting tool with a straight cylindrical shank, suited for CNC machining centers and manual mills running aluminum stock.

This end mill fits residential and commercial machine shop environments, production floors, and toolroom operations where close-tolerance aluminum milling is required. The 1/8 inch diameter and 2.5 inch overall length make it well suited for fine detail work, slot milling, and profiling in aluminum plate or extrusion. It is installed by machinists and CNC operators in applications where a compact, high-helix tool is specified for light-material high-speed cutting.

Key Features

• 45-degree helix angle promotes aggressive chip lift and reduced cutting pressure in aluminum
• 3-flute geometry balances chip room with surface finish quality
• Zplus coating provides lubricity and edge protection for non-ferrous applications
• Solid carbide construction delivers rigidity and wear resistance over high-speed tool paths
• Center-cutting design allows plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use in the HELICAL SOLUTIONS End Mills for Aluminum 3 Flute Square 45 Degree Helix series. Fits any CNC machining center or manual mill with a 1/8 inch collet, end mill holder, or matching straight-cylindrical shank toolholder.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. The tool must be seated fully and concentrically in a clean, undamaged collet or toolholder before tightening to the holder manufacturer's specification. Inspect the collet and taper for runout before use, as excessive runout at 1/8 inch diameter accelerates wear and can cause tool breakage. Power down and lock out the spindle before changing tooling.
