Helical Solutions 48061 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 48061 is a 3-flute solid carbide square end mill designed for high-performance aluminum milling applications. It features a 3/16-inch cutting diameter, a 1-inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation in non-ferrous materials. The Zplus coating reduces built-up edge and extends tool life in aluminum, cast aluminum, and similar soft alloys. A variable index geometry distributes cutting forces unevenly around the tool, reducing harmonic vibration and chatter during aggressive cuts. Licensed machinists, toolroom operators, and CNC programmers working in aluminum production or job shop environments will find this tool well-suited to finishing and semi-finishing passes.

This end mill is intended for aluminum and non-ferrous alloy milling on CNC machining centers and manual knee mills where a 3/16-inch straight-cylindrical shank can be held in a collet or end mill holder. The 3-inch overall length provides adequate reach for most standard workpiece setups without sacrificing rigidity at this diameter. The single-end, center-cutting configuration supports both peripheral milling and plunge entry. It fits the Helical Solutions End Mills for Aluminum series, which is engineered specifically around the chip load and surface finish requirements of aluminum alloys.

Key Features

• 3/16-inch cutting diameter with 1-inch length of cut for aluminum slotting and profiling
• 40-degree helix angle promotes aggressive chip evacuation in soft, gummy materials
• Zplus coating reduces built-up edge and extends tool life in aluminum alloys
• Variable index flute spacing lowers vibration and chatter during high-feed passes
• Center-cutting geometry allows direct plunge entry without a pre-drilled start hole
• Solid carbide construction provides rigidity and wear resistance at this small diameter

Compatibility

Designed for use in aluminum and non-ferrous alloy milling applications as part of the Helical Solutions End Mills for Aluminum series featuring 3-flute square geometry with 40-degree helix and variable pitch.

Installation Notes

Install in a precision collet or end mill holder sized for a 3/16-inch straight-cylindrical shank; ensure runout is minimized to protect tool life at this diameter. Confirm spindle direction is set to right-hand rotation before initiating a cut. Always follow your machine tool manufacturer guidelines for feed rate, depth of cut, and RPM when establishing a toolpath for this diameter. Secure the workpiece firmly before engaging the cutter to prevent movement under cutting load.
