Iscar 5507901 Carbide Replaceable Tip Drill 8mm IC908

Product Description

The ISCAR 5507901 is an ICM-series carbide replaceable tip drill insert designed for precision hole-making in demanding materials. The tip is manufactured from submicron solid carbide in the IC908 grade and carries a TiAlN coating applied via PVD process. It features a 140-degree included drill point angle with a thinned web and T-Land geometry, which reduces cutting forces at entry and improves chip evacuation. The slow spiral, two-flute design suits short-chipping and tough materials. At 8mm insert seat size with a functional length of 0.1650 inches and a height of 5.41mm (0.2130 inches), the insert mounts via a twist-lock holding method into compatible ICM-series drill bodies.

This replaceable tip insert is intended for production drilling operations in stainless steel, superalloys, and titanium as its primary workpiece materials. It is also rated for secondary use in steel, cast iron, and hard materials. Typical applications include aerospace component machining, oil and gas part production, and general precision metalworking where insert changeability reduces downtime. The ISO number ICM 080 identifies the compatible holder family. This insert is sold individually (package quantity of 1) and must be ordered in multiples of 2.

Key Features

• Submicron solid carbide IC908 grade for toughness and wear resistance in difficult-to-machine alloys
• TiAlN PVD coating enhances heat resistance and tool life in high-temperature cutting environments
• 140-degree drill point angle with thinned web reduces thrust force and improves centering
• T-Land cutting geometry supports stability when drilling stainless steel, superalloys, and titanium
• Slow spiral, two-flute design promotes controlled chip flow in short-chipping materials
• Twist-lock insert mounting for quick, repeatable tip changes without removing the drill body
• Conforms to ISO 13399 tool data standards for compatibility with digital tool management systems

Compatibility

Designed for use with ISCAR ICM-series replaceable tip drill bodies with an insert seat size of 8 (ISO number ICM 080). Confirm holder compatibility before ordering.

Installation Notes

Installation is performed by machining professionals using the twist-lock engagement method — ensure the mating drill body bore and seating surfaces are clean and free of chips before inserting the tip. Do not exceed the recommended torque specification listed in the ISCAR ICM toolholder documentation. Inspect the seating surfaces for wear at each tip change. Follow all applicable shop safety and machine lockout procedures before handling or changing cutting inserts.
