Helical Solutions 01105 Square End Mill 3 Flute 3/16 Inch

Product Description

The HELICAL SOLUTIONS 01105 is a 3-flute square end mill ground from solid carbide and designed specifically for aluminum milling applications. The cutter runs a 0.1875-inch diameter with a matching 0.1875-inch straight cylindrical shank, making it compatible with standard collet systems. A 35-degree right-hand helical flute geometry promotes efficient chip evacuation and reduces built-up edge when cutting aluminum alloys. The bright, uncoated finish is well-suited for non-ferrous materials where coating adhesion is a common concern. This tool is installed and operated by machinists and CNC programmers working in job shops, production facilities, and aerospace or prototype environments.

This end mill is intended for slotting, profiling, and pocketing operations in aluminum and other non-ferrous materials. The 0.5625-inch length of cut and 2.5-inch overall length make it a practical choice for shallow-to-moderate depth passes in vertical machining centers and CNC mills. The non-extended-reach design keeps the tool stiff and resistant to deflection during high-speed aluminum roughing and finishing passes. It is cataloged under the Helical Solutions End Mills for Aluminum series, 3-flute square, 35-degree helix.

Key Features

• Solid carbide construction for rigidity and wear resistance in aluminum cutting
• 3-flute, 35-degree right-hand helix geometry for fast chip evacuation in non-ferrous materials
• Center-cutting capability allows plunge entry without a pre-drilled hole
• Bright, uncoated finish optimized for aluminum and other non-ferrous alloys
• Straight cylindrical shank fits standard ER collets and end mill holders
• Square end profile suited for flat-bottom slots, pockets, and shoulder milling

Compatibility

Designed as an OEM-style replacement or direct-use tool for CNC machining centers and manual mills equipped with standard collet systems accepting a 0.1875-inch straight shank. Best suited for aluminum alloys and other non-ferrous materials as specified by the Helical Solutions End Mills for Aluminum series designation.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and the tool changer or spindle locked before inserting or removing the end mill from the collet or holder. Ensure the collet bore is clean and free of chips before seating the shank to the correct insertion depth per the holder manufacturer specification. Verify runout with a dial indicator after tool installation before beginning any cut.
