Iscar 5508464 Carbide Replaceable Tip Drill 0.626in IC908

Product Description

The ISCAR 5508464 is a carbide replaceable tip drill from the ICM series, designed for precision hole-making in demanding materials including stainless steel, superalloys, and titanium. The drill tip carries the IC908 grade designation, produced from submicron solid carbide with a PVD-applied TiAlN coating for heat resistance and extended edge life. The cutting diameter measures 0.626 inches (16.00 mm) and the included point angle is 140 degrees, a geometry suited to work-hardening materials where controlled entry and minimal thrust are priorities. Two helical flutes and a web-thinned design support chip evacuation in deep-hole and interrupted-cut conditions. Licensed HVAC techs, machinists, and tooling specialists in metalworking environments are the primary installers of this tool type.

The ICM series replaceable tip drill is applied in CNC machining centers and drilling operations targeting stainless steel and superalloy workpieces as the primary material group. Secondary workpiece materials include steel, cast iron, and hard materials. The tip mounts via a clamp holding method into an ICM-compatible insert seat size 15 body. The ISO number for this tip is ICM 159, and the tip conforms to ISO 13399 standards for cutting tool data representation. This configuration is common in aerospace, energy, and precision manufacturing applications where carbide tip replacement reduces per-hole tooling cost versus solid carbide drill replacement.

Key Features

• Solid carbide IC908 submicron grade tip with PVD TiAlN coating for elevated-temperature wear resistance
• 140-degree point angle optimized for stainless steel, superalloys, and titanium entry control
• 0.626 inch (16.00 mm) cutting diameter with web-thinned geometry for reduced thrust load
• Two helical flutes with regular spiral for consistent chip flow
• Clamp-style insert holding in ICM series seat size 15 body — replaceable tip design lowers cost per hole
• Conforms to ISO 13399 cutting tool data standards

Compatibility

Designed for use with ICM series drill bodies accepting insert seat size 15. ISO tip designation ICM 159. Compatible primary workpiece materials are stainless steel, superalloys, and titanium (ISO material codes M and S). Secondary compatible materials include steel, cast iron, and hard materials (ISO material codes P, K, and H).

Installation Notes

This replaceable tip is installed by qualified machinists or tooling technicians following the machine tool manufacturer and ISCAR body-specific torque and seating procedures. Power down and lock out the spindle before tip removal or installation. Inspect the insert seat for chips or debris before seating the new tip to ensure full contact and prevent runout. Do not exceed the cutting parameters published in the ISCAR ICM series application guide for the workpiece material being machined.
