Iscar 5508574 Replaceable Drill Tip 0.681 in IC908

Product Description

The ISCAR 5508574 is a replaceable carbide drill tip designed for use with compatible ICP-series modular drill bodies. It features a 0.6810-inch (17.00 mm) cutting diameter with a 140-degree point angle and a standard helical flute geometry. The tip is manufactured from submicron solid carbide in grade IC908 and finished with a PVD-applied TiAlN coating, giving it strong thermal and wear resistance during high-productivity hole-making operations. With an overall projection of 0.3900 inches and a flute length of 7.00 mm, this tip fits insert seat size 17 and is installed using a clamp-type holding method. Metalworking professionals including machinists and toolroom technicians install this tip in production drilling applications.

This replaceable drill tip is suited for hole making, chamfering, and general drilling operations. Its primary workpiece material rating is steel (ISO P), with secondary ratings covering stainless steel, cast iron, superalloys, titanium, and hard materials (ISO M, K, S, H). The web-thinned geometry reduces thrust forces at entry, making it a practical choice for medium-to-high volume production environments where insert change-outs must be fast and repeatable. The tip conforms to ISO 13399 cutting tool data standards.

Key Features

• Submicron solid carbide grade IC908 construction for extended tool life in steel and stainless applications
• PVD TiAlN coating provides thermal barrier and reduces built-up edge in ferrous materials
• 140-degree point angle with web-thinned geometry reduces entry thrust and improves hole quality
• Clamp-type insert holding method for secure seating and quick tip changes
• 2-flute regular spiral configuration with helical flute form promotes chip evacuation
• ISO 13399 compliant for integration with digital tool management systems

Compatibility

Designed as a replaceable drill tip for ICP-series modular drill bodies requiring insert seat size 17, conforming to ISO 13399 cutting tool standards. Refer to the ICP series body specifications to confirm seat size and style compatibility before installation.

Installation Notes

This tip is installed and removed by machining tradespeople using the appropriate clamping hardware specified by the drill body manufacturer. Power down the machine and follow lockout/tagout procedures before servicing or replacing the insert. Inspect the insert seat for damage, chips, or debris before seating the new tip, as a compromised seat will affect runout and hole accuracy. Do not exceed the cutting parameters recommended for IC908 grade and the workpiece material being machined.
