Helical Solutions 59838 Square End Mill 1/4 in 5 Flute Carbide

Product Description

The HELICAL SOLUTIONS 59838 is a 5-flute, solid carbide square end mill designed for high-performance milling in demanding machining environments. With a 1/4 inch cutting diameter and a 3/4 inch length of cut, this tool delivers clean, accurate results across a wide range of materials. The Tplus coating provides enhanced wear resistance and lubricity, extending tool life in difficult-to-machine alloys and steels. A variable index flute geometry reduces harmonic vibration during cutting, improving surface finish and allowing for higher feed rates. This end mill is suited for machinists and toolroom professionals running CNC mills and machining centers.

The 59838 is well suited for slot milling, peripheral milling, and profiling operations on CNC machining centers and vertical mills. Its 1/4 inch straight cylindrical shank fits standard collets and tool holders in that size range. The 5-flute design is optimized for finishing and semi-finishing passes in ferrous materials, hardened steels, and high-temp alloys where chip evacuation and surface quality are priorities. The right-hand cutting and right-hand helical flute direction are standard for conventional CNC milling setups.

Key Features

• 5-flute solid carbide construction for rigidity and wear resistance
• Tplus coating for improved lubricity and extended tool life in hard materials
• Variable index flute spacing reduces chatter and vibration during cutting
• Right-hand cut and right-hand helix for standard CNC milling applications
• Centercutting capable, allowing plunge entry into workpieces
• Straight cylindrical shank fits standard 1/4 inch collets and tool holders

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 1/4 inch collet tool holders on CNC machining centers and vertical mills.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder and verify runout with a dial indicator before beginning a cut. Follow the tool manufacturer and machine builder recommendations for speeds, feeds, and depth of cut for the specific workpiece material.
