Iscar 5508571 Carbide Replaceable Tip Drill 0.669 in

Product Description

The ISCAR 5508571 is a carbide replaceable tip drill insert from the ICP series, designed for high-performance drilling in demanding metal-cutting applications. The insert is manufactured from submicron solid carbide in the IC908 grade and carries a PVD-applied TiAlN coating for extended tool life and heat resistance at the cutting edge. The drill tip features a 140-degree included point angle with a thinned web geometry and a honed cutting edge, reducing entry forces and improving hole quality. It measures 0.669 inches in cutting diameter and 0.390 inches in functional length. Two spiral flutes in a slow-spiral configuration promote chip evacuation during drilling operations.

This insert is intended for use in ICP-series replaceable tip drill bodies, seat size 17, and is suited for drilling steel as its primary workpiece material. Secondary workpiece materials include stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO material groups P, M, K, S, and H. Typical installations occur in CNC machining centers and turning centers where consistent hole geometry and repeatable insert indexing are required. The ISO number for this insert is ICP 170, per ISO 13399 tooling data standards.

Key Features

• Submicron solid carbide construction in IC908 grade for toughness and wear resistance
• PVD TiAlN coating extends tool life in steel and stainless steel drilling
• 140-degree thinned-web point reduces thrust force and improves centering
• Honed cutting edge finish for improved edge stability in interrupted cuts
• Slow-spiral, two-flute design promotes controlled chip flow
• Conforms to ISO 13399 tooling data standards for system integration

Compatibility

Designed for use with ICP-series replaceable tip drill bodies requiring insert seat size 17. Compatible ISO number is ICP 170. Verify seat size and series designation on the drill body before installation.

Installation Notes

Replaceable tip drill inserts of this type are installed and removed by machinist or toolroom personnel using the manufacturer-specified torque key for the ICP system. Ensure the drill body seat is clean and free of chips or debris before seating the insert. Confirm correct rotational orientation before securing. Always follow machine lockout procedures before changing inserts in a live spindle.
