Helical Solutions 48116 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 48116 is a 3-flute solid carbide square end mill designed for high-performance milling in metal, alloy, and composite workpiece materials. It features a 1/4 inch cutting diameter, a 3/4 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and reduced cutting forces. The Zplus coating improves wear resistance and extends tool life in ferrous and non-ferrous applications. Variable index flute spacing reduces chatter and improves surface finish at higher feed rates. This tool is single-end, right-hand cutting, and right-hand spiral, suited for use in CNC machining centers and manual mills operated by machinists and tool-and-die professionals.

This end mill is well suited for slotting, profiling, and peripheral milling operations in job shop, production, and maintenance machining environments. The 1/4 inch straight cylindrical shank fits standard ER collet chucks and end mill holders commonly found on vertical machining centers and small-frame CNC routers. The center-cutting geometry allows direct plunge entry without a pilot hole. The compact 2.5 inch overall length provides rigidity in tight-clearance setups where extended-reach tooling is not required.

Key Features

• 1/4 inch cutting diameter with 3/4 inch length of cut for short, rigid reach
• 3-flute solid carbide construction for strength and wear resistance
• 40-degree helix angle promotes smooth chip flow and reduces cutting pressure
• Zplus coating extends tool life in ferrous and non-ferrous materials
• Variable index flute geometry reduces harmonic chatter during high-feed passes
• Center-cutting design permits direct plunge milling without pre-drilling

Compatibility

Designed as a direct-fit replacement or standard selection for 1/4 inch ER collet chucks, end mill holders, and hydraulic toolholders accepting straight cylindrical shanks on CNC vertical machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before inserting or removing any tooling. Seat the shank fully into the collet or holder to the recommended gauge-line depth before torquing the retention nut. Verify runout with a dial indicator before beginning a production cut to avoid premature tool wear or workpiece damage.
