Iscar 5567946 Replaceable Drill Tip 0.4373 in IC908

Product Description

The ISCAR 5567946 is a replaceable drill tip in the HCP-IQ series, designed for use with compatible indexable drill bodies that accept an insert seat size 11. Made from solid carbide with a submicron material grade and a PVD-applied TiAlN coating, this tip delivers thermal and wear resistance in demanding cutting environments. It measures 0.4373 inches (11.10 mm) in cutting diameter and features a 139-degree included point angle with a self-centering point geometry. The web-thinned design and regular helical spiral reduce entry force and chip load. Licensed machinists and CNC operators handling production drilling work are the primary installers.

This drill tip is suited for hole making, chamfering, and general drilling operations in steel, cast iron, stainless steel, superalloys, titanium, and hard materials. The IC908 grade targets interrupted cuts and high-productivity runs in ISO material groups P, K, M, S, and H. It is packaged individually (quantity of 1 per package) with a minimum order quantity of 2. Typical applications include production machining centers where quick tip replacement without full tool changeover is required.

Key Features

• Solid carbide construction with submicron material grade for edge integrity under high cutting loads
• PVD TiAlN coating provides oxidation resistance and extended tool life in ferrous and hard materials
• 139-degree self-centering point angle reduces pilot requirements and improves positional accuracy
• Web-thinned geometry lowers axial thrust and supports chip evacuation in blind and through holes
• 2-flute helical design with regular spiral for balanced chip flow
• Clamp-held insert seat size 11 enables fast tip replacement without disturbing the drill body setup

Compatibility

Designed as a replaceable tip for HCP-IQ series indexable drill bodies that accept insert seat size 11, conforming to ISO 13399 standards. ISO number reference: HCP 111-IQ.

Installation Notes

Installation is performed by CNC machinists or tool-room technicians. The drill body must be fully de-energized and the machine brought to a safe stop before tip replacement. Use the correct torque wrench and clamp hardware specified for the HCP-IQ seat to avoid seat damage or tip movement under load. Do not exceed the recommended cutting parameters for the IC908 grade when machining hardened or abrasive workpiece materials.
