Helical Solutions 01345 Square End Mill 3/8 Inch 3 Flute

Product Description

The HELICAL SOLUTIONS 01345 is a 3-flute solid carbide square end mill designed for high-performance milling in aluminum and non-ferrous materials. With a 3/8 inch (0.375 inch) mill diameter and a 35-degree right-hand helical flute geometry, this tool promotes efficient chip evacuation and reduces built-up edge common in aluminum cutting. The bright, uncoated finish maintains sharp cutting edges and suits applications where coating adhesion to soft materials is a concern. It is center-cutting, allowing plunge entry into workpieces. Machinists and tool-and-die professionals working on CNC mills and manual mills will find this an effective general-purpose end mill for aluminum and similar alloys.

This end mill is suited for milling operations in aluminum, brass, and other non-ferrous materials across job shops, production machining environments, and tool rooms. The 1-inch length of cut paired with a 3-inch overall length provides adequate reach for shoulder milling, slotting, and profiling operations on light to medium-depth features. The straight cylindrical shank at 3/8 inch diameter fits standard ER collets and end mill holders commonly found in vertical machining centers and manual knee mills.

Key Features

• 3/8 inch solid carbide construction for rigidity and wear resistance
• 3-flute design optimized for aluminum chip evacuation and surface finish
• 35-degree right-hand helix angle reduces cutting forces and improves chip flow
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Bright uncoated finish suitable for non-ferrous and soft material applications
• Straight cylindrical shank compatible with standard collet and end mill holder systems

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC and manual milling machines accepting 3/8 inch straight shank end mills via ER collets or end mill holders. No specific machine model compatibility is stated by the manufacturer for this part.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine in a full stop and all motion axes locked. Ensure the collet or tool holder is clean and free of chips before seating the shank. Confirm runout with a dial indicator before production cuts. Follow the machine builder and tooling manufacturer guidelines for feed rates and speeds appropriate to the workpiece material.
