Helical Solutions 44062 Square End Mill 3/16 in 5 Flute Carbide

Product Description

The HELICAL SOLUTIONS 44062 is a 5-flute solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 3/16 inch mill diameter and a 5/16 inch length of cut, this end mill delivers clean, accurate results in tight-tolerance work. The Aplus coating improves wear resistance and tool life across a range of ferrous and non-ferrous materials. The variable index flute spacing reduces chatter and vibration during cutting, making it well suited for high-speed finishing and semi-finishing passes. A right-hand cutting and right-hand helical flute geometry promotes efficient chip evacuation.

This end mill is used in CNC milling operations across job shops, tool rooms, and production machining environments. The 3/16 inch shank diameter and 2 inch overall length make it compatible with standard collet and end mill holder tooling setups on vertical and horizontal machining centers. It is a single-end, straight-cylindrical shank tool suited for side milling, slotting, and contouring in both steel and alloy workpieces. The centercutting capability allows plunge entry directly into workpiece material without pre-drilling.

Key Features

• 5-flute design with variable index spacing reduces vibration and improves surface finish
• Solid carbide construction provides rigidity and heat resistance at elevated cutting speeds
• Aplus coating extends tool life and reduces friction in ferrous material applications
• Centercutting geometry enables direct plunge milling without a pilot hole
• Right-hand helical flute promotes upward chip evacuation and reduces re-cutting
• Straight-cylindrical shank fits standard collet chucks and end mill holders

Compatibility

Designed as a direct-fit replacement or production-use end mill for CNC machining centers and manual milling machines accepting a 3/16 inch straight-cylindrical shank toolholder or collet.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Ensure the collet or toolholder bore is clean and free of debris before seating the shank. Torque the toolholder to the machine or toolholder manufacturer specifications — do not over-tighten collet nuts by hand estimation alone. Confirm runout with a dial indicator before beginning a production cut.
