Iscar 5509266 Carbide Replaceable Tip Drill IC908

Product Description

The ISCAR 5509266 is a carbide replaceable tip drill insert designed for use in compatible ICP-series drill bodies. Manufactured under the IC908 grade with a submicron carbide substrate, this insert uses a PVD-applied TiAlN coating to maintain cutting-edge hardness and thermal resistance under demanding conditions. The insert features a 140-degree included angle with a thinned web point and a slow spiral, honed cutting-edge geometry. Cutting diameter is 0.764 inches and functional length is 0.317 inches. It is intended for machinists and tooling technicians working in production drilling operations on ferrous and difficult-to-machine materials.

This insert is suited for drilling steel as its primary workpiece material, with secondary capability in stainless steel, cast iron, super-alloys, titanium, and hard materials. The P-geometry insert seats into an ICP series drill body at insert seat size 19. Typical applications include production drilling in ISO material groups P, M, K, S, and H. It conforms to ISO 13399 tooling data standards, making it compatible with digital tool management systems used in CNC machining environments.

Key Features

• IC908 submicron solid carbide grade for toughness and wear resistance in steel and hard materials
• PVD TiAlN coating provides thermal barrier and extends tool life in dry or minimal-coolant cuts
• 140-degree included angle with thinned web point reduces entry forces and improves centering
• Slow spiral, honed cutting-edge geometry suited for controlled chip evacuation in short-hole drilling
• 2-flute spiral design with twist insert-holding method for secure, repeatable tip seating
• Conforms to ISO 13399 for integration with digital tooling libraries and CNC presetting systems

Compatibility

Designed for use in ICP-series replaceable tip drill bodies accepting insert seat size 19 and ISO Number ICP 194. No coolant-through capability is required in the host body for this insert configuration.

Installation Notes

Replaceable tip drill inserts of this type are installed and removed by tooling technicians using the torque tool specified by the drill body manufacturer — do not use substitutes. Ensure the drill body shank and insert seat are clean and free of chips before seating the tip. Confirm tip is fully locked before mounting the assembly in the spindle. Follow the machine tool builder and insert manufacturer guidelines for compatible cutting parameters for the workpiece material group.
