Iscar 5508323 Carbide Replaceable Tip Drill 9mm IC908

Product Description

The ISCAR 5508323 is a solid carbide replaceable tip drill in the ICM series, designed for precision hole-making in demanding materials. The tip carries an IC908 grade designation with a submicron carbide substrate and a PVD-applied TiAlN coating for heat and wear resistance. It features a 9.00mm cutting diameter, a 140-degree drill point angle, and a standard helical two-flute geometry with web thinning for improved chip evacuation and reduced thrust. This drill tip is installed and replaced by machinists and toolroom technicians in CNC drilling applications where consistent hole quality and tool life are required.

The 5508323 is suited for drilling operations in stainless steel, superalloys, and titanium as its primary workpiece materials. It also performs in steel, cast iron, and hard materials as secondary applications. The tip mounts into an ICM series holder using a clamp insert holding method at an insert seat size of 8. Typical use cases include production drilling on CNC machining centers and lathes where replaceable tip systems reduce setup time compared to full solid-carbide drills.

Key Features

• IC908 submicron carbide grade with PVD TiAlN coating for high-temperature wear resistance
• 140-degree drill point angle with standard point type for broad material compatibility
• Web-thinned geometry reduces axial thrust and improves chip flow
• Two-flute regular spiral design for stable, consistent chip evacuation
• Clamp-style insert holding method for repeatable tip indexing in ICM series holders
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use with ICM series replaceable tip drill holders at insert seat size 8. ISO number reference: ICM 086. Coolant-through holders are not required; this tip does not support internal coolant delivery.

Installation Notes

Installation is performed by toolroom technicians or machinists familiar with replaceable tip drill systems. Power down and de-energize the machine spindle before seating or removing the tip. Use the correct torque wrench and clamp screw as specified by the ISCAR ICM holder instructions — do not over-torque the clamping screw or seat the tip without proper alignment to the locating features. Inspect the holder seat for chips or damage before each tip change to ensure accurate seating and runout.
