Iscar 5506739 Carbide Replaceable Tip Drill IC908

Product Description

The ISCAR 5506739 is a solid carbide replaceable tip drill designed for high-performance hole-making in demanding materials. Belonging to the ICM series, it carries the IC908 manufacturer grade and a PVD-applied TiAlN finish that resists heat and wear during aggressive cutting cycles. The drill features a 1.26 inch cutting diameter, a 140-degree included drill point angle, and a thinned point geometry for reduced thrust. With two slow-spiral flutes and a T-Land style edge, it is engineered for stable chip evacuation and edge strength. Licensed machinists and CNC operators in metalworking shops are the typical end users for this tool.

This replaceable tip drill is rated for primary use in stainless steel, superalloys, and titanium, making it well suited for aerospace, medical, and energy sector components. It also handles steel, cast iron, and hard materials as secondary workpiece materials. The ICM series design allows the carbide tip to be swapped without removing the drill body from the machine, reducing downtime during production runs. The insert seat size is 32 mm and the ISO number is ICM 320, which governs tip-to-body compatibility within the ICM platform.

Key Features

• IC908 submicron solid carbide grade with PVD TiAlN coating for extended tool life in hard and heat-resistant alloys
• 140-degree thinned point reduces entry thrust and improves self-centering on entry
• Slow-spiral, two-flute geometry promotes controlled chip flow in tough, stringy materials
• T-Land cutting edge style provides added edge stability and resistance to chipping
• Web-thinned construction lowers cutting forces across the full diameter
• Replaceable tip design allows tip changes at the spindle, minimizing changeover time

Compatibility

The 5506739 tip is compatible with ICM series drill bodies using a 32 mm insert seat, conforming to ISO 13399 standards. Verify body ISO number ICM 320 before ordering to confirm tip-to-body fitment.

Installation Notes

Installation and tip changes should be performed by qualified machinists following the machine tool manufacturer's lockout and spindle-stop procedures before accessing the tool holder. Use the correct torque wrench and ISCAR-specified keys when seating the replaceable tip to ensure proper clamping without damaging the carbide seat. Confirm correct tip orientation and full seating before resuming spindle operation. Follow applicable shop safety and machine guarding protocols at all times.
