Helical Solutions 01180 Square End Mill 0.25in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 01180 is a 3-flute solid carbide square end mill designed for high-performance milling in aluminum and non-ferrous materials. The 0.25-inch diameter cutting geometry features a 35-degree right-hand helical flute with a bright, uncoated finish suited for applications where coating buildup or heat sensitivity is a concern. With a 1-inch length of cut and a 3-inch overall length, this tool balances reach and rigidity for slotting, profiling, and peripheral milling operations. Centercutting capability allows plunge entry. Machinists and tool-and-die professionals specify this geometry for aluminum finishing and semi-finishing work where chip evacuation and surface finish are critical.

This end mill is optimized for aluminum milling in CNC machining centers and manual mills. The 3-flute configuration offers a balance between the chip clearance of a 2-flute and the feed rate capability of a 4-flute, making it a common choice for aluminum plate work, aerospace components, and general job shop operations. The straight-cylindrical shank accepts standard collet chucks and end mill holders sized for 0.25-inch shank tooling. No extended reach geometry is present, keeping the tool compact and suitable for standard-depth pockets and slots.

Key Features

• 35-degree right-hand helical flute for efficient chip evacuation
• Centercutting design allows direct plunge entry without pilot drilling
• Bright, uncoated finish — no coating buildup risk in sticky aluminum alloys
• Straight-cylindrical 0.25-inch shank fits standard collet and end mill holders
• 1-inch length of cut with 3-inch overall length for compact rigidity

Compatibility

Designed for use in CNC machining centers and manual mills with 0.25-inch collet chucks or end mill holders; part of the Helical Solutions End Mills for Aluminum 3-Flute Square 35-degree Helix series.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the spindle is fully stopped and power is off before changing tooling. Seat the shank fully in the collet or end mill holder to the recommended gauge length and torque the retention nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before cutting to maximize tool life and surface finish quality.
