Helical Solutions 48115 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 48115 is a solid carbide square end mill designed for aluminum machining applications. It features a 1/4 inch diameter with a 3/4 inch length of cut and a 40-degree helix angle that promotes efficient chip evacuation in aluminum and other non-ferrous materials. The three-flute geometry paired with a variable index design reduces harmonic vibration during cutting, contributing to improved surface finish and longer tool life. At 2.5 inches overall length with a 1/4 inch straight cylindrical shank, this end mill fits standard tool holders used in vertical machining centers and CNC mills. Installation and use require a licensed or experienced machinist or CNC operator.

This end mill belongs to the HELICAL SOLUTIONS End Mills for Aluminum series featuring a 3-flute square profile with a 40-degree helix and variable pitch. It is suited for slotting, profiling, and peripheral milling in aluminum alloys and soft non-ferrous materials. The single-end, right-hand cut and right-hand flute configuration is standard for conventional CNC milling setups. The bright uncoated finish makes it well suited for aluminum where coatings can cause built-up edge. Typical use cases include aerospace component work, mold work in aluminum, and general production machining of aluminum billet.

Key Features

• Solid carbide construction for rigidity and wear resistance in aluminum milling
• 40-degree helix angle promotes aggressive chip evacuation and reduced cutting force
• Variable index flute spacing reduces harmonic chatter for improved surface finish
• Center cutting capable, allowing plunge entry into workpiece material
• Right-hand cut and right-hand helix for standard CNC spindle compatibility
• Bright uncoated finish prevents aluminum adhesion and built-up edge

Compatibility

Designed as an OEM-style replacement end mill for use in standard 1/4 inch straight-shank tool holders on CNC vertical machining centers and manual mills. Belongs to the HELICAL SOLUTIONS End Mills for Aluminum - 3 Flute - Square - 40 deg Helix - Variable Pitch series.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the tool holder is clean and free of debris before seating the end mill. Secure the shank to the full grip depth recommended for the tool holder type to prevent pull-out under cutting loads. Follow applicable shop safety procedures and machine manufacturer guidelines for tool runout inspection before beginning a cut.
