Helical Solutions 59834 Square End Mill 3/16 in 5 Flute Carbide

Product Description

The HELICAL SOLUTIONS 59834 is a 5-flute solid carbide square end mill designed for precision milling in demanding shop and production environments. With a 3/16-inch diameter and a 5/16-inch length of cut, this tool is built for finishing and semi-finishing passes where tool rigidity and surface finish matter. The Tplus coating reduces friction and extends tool life in ferrous and non-ferrous materials. A variable index flute spacing minimizes harmonic vibration during cutting, improving both finish quality and tool longevity. This end mill is installed and operated by machinists and CNC programmers in job shop, aerospace, and general machining applications.

This end mill is suited for milling slots, pockets, and profiles in materials where a compact-diameter tool is required. The 3/16-inch straight-cylindrical shank fits standard collet chucks and end mill holders. With a 2-inch overall length, it provides a stable reach-to-diameter ratio appropriate for shallow-to-mid-depth features. Right-hand cutting and right-hand helical flutes make it compatible with conventional CNC milling setups. Centercutting geometry allows for direct plunge entry where required.

Key Features

• 5-flute design increases feed rate potential and improves surface finish compared to standard 4-flute tools
• Variable index flute spacing reduces chatter and vibration during cutting
• Tplus coating improves wear resistance and reduces heat buildup at the cutting edge
• Centercutting geometry allows plunge milling without a pre-drilled pilot hole
• Right-hand cut, right-hand helix — compatible with standard CNC milling spindle direction
• Solid carbide construction provides rigidity and dimensional stability in tight-tolerance work

Compatibility

Designed for use in standard collet chucks and end mill holders accepting a 3/16-inch straight-cylindrical shank, compatible with CNC machining centers and manual knee mills configured for right-hand cutting tools.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the holder. Seat the shank fully into the collet or end mill holder and torque the retention nut per the toolholder manufacturer specification. Verify runout with a dial indicator before initiating a cut to protect both the tool and the workpiece.
