Iscar 5509972 Carbide Replaceable Tip Drill 0.728 in IC908

Product Description

The ISCAR 5509972 is a carbide replaceable tip drill from the FCP series, designed for high-productivity drilling in ferrous and hard materials. The drill tip is manufactured from submicron solid carbide with an IC908 grade and a PVD-applied TiAlN coating that extends edge life in demanding cutting conditions. It carries a 0.728-inch cutting diameter, a 140-degree included drill point angle, and a flat-bottom style geometry. The two-flute slow spiral flute configuration and web-thinned point promote chip evacuation and reduce entry thrust, making this tool well suited for production drilling operations performed by machinists and toolroom technicians.

This replaceable tip drill is intended for drilling applications in steel, cast iron, stainless steel, super-alloys, titanium, and hard materials, covering ISO material groups P, K, M, S, and H. The flat-bottom, thinned-point geometry makes it a practical choice for through-hole and blind-hole work on CNC machining centers and drill presses where consistent bore quality in tough workpiece materials is required. It conforms to ISO 13399 standards for cutting tool data representation, allowing straightforward integration into tool management and presetter systems.

Key Features

• Submicron solid carbide tip with IC908 grade for wear resistance in steel and cast iron
• PVD TiAlN coating extends tool life in high-temperature cutting environments
• 140-degree included angle with web-thinned point reduces entry thrust and improves centering
• Flat-bottom style geometry suitable for flat-bottomed holes and shallow drilling
• Two-flute slow spiral design promotes controlled chip flow in short-chipping materials
• Conforms to ISO 13399 cutting tool data standard

Compatibility

Designed for use in ISCAR FCP series replaceable tip drill bodies accepting insert seat size 18, ISO number FCP 185. Verify body compatibility before ordering.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a fully stopped and locked-out state. Use the appropriate torx or hex key as specified by the drill body manufacturer to seat the replaceable tip securely using the twist-lock holding method. Do not exceed the recommended axial runout tolerance for the drill body. Inspect the seating surface of the drill body for chips or damage before installing a new tip.
