Helical Solutions 30317 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 30317 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard materials. With a 3/8 inch cutting diameter and 4-flute helical geometry, this single-end tool delivers clean square shoulders and efficient chip evacuation at aggressive feed rates. The APLUS coating provides enhanced hardness and heat resistance, extending tool life in abrasive and high-temperature cutting conditions. A variable index flute spacing reduces harmonic vibration during cut, improving surface finish and dimensional accuracy. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills where consistent edge integrity is critical.

This end mill suits a wide range of material removal tasks in job shop, production, and maintenance machining environments. It is well suited for slotting, peripheral milling, and profiling operations on ferrous and non-ferrous workpiece materials. The 1/2 inch length of cut and 2 inch overall length make it practical for shallow-to-moderate depth passes. The straight-cylindrical shank fits standard ER collet chucks, end mill holders, and milling machine spindles accepting 3/8 inch shank tooling.

Key Features

• 3/8 inch cutting diameter with 1/2 inch length of cut for controlled material removal
• 4-flute helical right-hand flute configuration for efficient chip flow
• APLUS coating increases surface hardness and thermal resistance for longer tool life
• Variable index flute spacing reduces chatter and improves finish quality
• Centercutting geometry allows plunge entry into the workpiece
• Straight-cylindrical shank for broad holder compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting 3/8 inch straight-cylindrical shank end mills.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware according to the holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.
