Htc 200-4062 Square End Mill 1/16 in 4 Flute Solid Carbide

Product Description

The HTC 200-4062 is a double-end, four-flute square end mill designed for precision milling in hard and abrasive materials. Built from solid carbide, it carries an AlTiN (aluminum titanium nitride) coating that extends tool life under high-heat cutting conditions. The mill diameter is 0.0625 inches (1/16 inch), with a length of cut of 0.125 inches (1/8 inch) and an overall length of 1.5 inches. The stub-length profile and 1/8-inch square shank make it well suited for tight-tolerance work where rigidity and minimal deflection are priorities. Right-hand cutting and right-hand helical flutes are standard on this Series 200 tool.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The AlTiN coating makes it appropriate for dry or semi-dry cutting in hardened steels, stainless steels, and high-temp alloys. The small diameter and stub length are common in applications requiring fine detail work, mold and die machining, or any setup where workpiece clearance is limited. Machinists and tool and die makers are the primary end users.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating improves heat resistance and extends tool life in dry cutting applications
• Four-flute helical design provides efficient chip evacuation and improved surface finish
• Double-end configuration offers two usable cutting ends, extending tool service life
• Stub-length (Series 200) profile reduces deflection during precision milling operations
• Right-hand cut and right-hand flute geometry compatible with standard CNC spindle rotation

Compatibility

Designed as a standard 1/8-inch shank square end mill compatible with CNC machining centers and manual mills equipped with collets or toolholders accepting 0.125-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully and evenly in the collet or toolholder and tighten to the toolholder manufacturer's specified clamping procedure. Verify runout with a dial indicator before beginning a new cut, particularly when working at small diameters where even minor runout can cause premature tool failure.
