Helical Solutions 48310 3 Flute Square End Mill 3/8 in

Product Description

The HELICAL SOLUTIONS 48310 is a 3-flute solid carbide square end mill designed for high-performance milling in aluminum and non-ferrous materials. It features a 3/8-inch (0.375 inches) mill diameter with a matching 3/8-inch straight shank, a 1.5-inch length of cut, and a 40-degree helix angle optimized to evacuate chips efficiently in soft, gummy metals. Variable index geometry reduces harmonic vibration during cutting, extending tool life and improving surface finish. The centercutting design allows plunge entry. This tool is intended for use by machinists and CNC operators in job shop, production, and toolroom environments.

The 48310 is built for aluminum and non-ferrous workpiece materials, making it a practical choice for aerospace, automotive, and general fabrication applications where clean chip evacuation and finish quality are critical. Its 3.5-inch overall length provides reach for standard depth cuts without sacrificing rigidity. The single-end, right-hand cutting and right-hand flute configuration is the standard orientation for conventional CNC milling centers and manual knee mills. No coolant-through feature is present, so flood or mist coolant is applied externally at the cutting zone.

Key Features

• 3-flute solid carbide construction for rigidity and wear resistance in non-ferrous applications
• 40-degree helix angle promotes efficient chip evacuation in aluminum
• Variable index pitch reduces chatter and harmonic vibration
• Centercutting capable — supports direct plunge entry without a pre-drilled hole
• Bright/uncoated finish suited for aluminum where coating adhesion can cause built-up edge
• Right-hand cut and right-hand flute, single-end configuration for standard CNC setups

Compatibility

Designed for use in aluminum and non-ferrous materials as an end mill in CNC machining centers, routers, and manual milling machines accepting a 3/8-inch straight shank toolholder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the straight shank in a properly sized collet, end mill holder, or set-screw holder rated for the shank diameter before operation. Verify runout with a dial indicator after tool installation — excessive runout accelerates edge wear and degrades surface finish. Power down and lock out the spindle before changing tooling.
