Iscar 5508325 Carbide Tip Drill Insert Tialn 0.346 in

Product Description

The ISCAR 5508325 is a solid carbide replaceable tip drill insert in the ICM series, designed for use in compatible modular drill body systems. It carries a TiAlN coating applied via PVD process and features a 140-degree drill point angle with a thinned web point style. The cutting diameter is 0.346 inches (8.79 mm), the functional length is 0.159 inches, and the overall height is 0.213 inches (5.41 mm). The IC908 submicron carbide grade and T-Land geometry make this insert well suited for demanding hole-making operations in difficult workpiece materials. Licensed machinists and CNC operators typically source and install these tips.

This insert is intended for drilling operations on stainless steel, superalloys, and titanium as primary workpiece materials, with secondary suitability for steel, cast iron, and hard materials. The slow spiral, two-flute configuration and web-thinned point support chip evacuation and entry stability in these applications. It conforms to ISO 13399 standards for cutting tool data representation. Coolant-through capability is not supported by this insert. Typical use is in production machining environments where tip replacement extends the life of the drill body without replacing the full tool assembly.

Key Features

• Solid carbide IC908 submicron grade for hardness and wear resistance in difficult materials
• TiAlN coating via PVD process for thermal and oxidation resistance
• 140-degree thinned web point reduces thrust force at drill entry
• Slow spiral, two-flute design supports chip flow in stainless steel, superalloys, and titanium
• T-Land insert geometry improves edge stability during interrupted or demanding cuts
• Conforms to ISO 13399 cutting tool data standard

Compatibility

Designed as a replaceable tip insert for compatible ISCAR ICM series modular drill bodies using insert seat size 8. ISO number ICM 088 identifies the matching body interface.

Installation Notes

Replaceable tip drill inserts of this type are installed and removed by machining technicians using the twist-lock method specified for the ICM series body. The machine spindle must be fully stopped and the tool cleared of the workpiece before tip replacement. Follow the drill body manufacturer torque and seating instructions for the specific body model. Inspect the insert seat for wear or debris before seating a new tip to ensure proper alignment and runout.
