Iscar 5509557 Carbide Replaceable Tip Drill 0.327 in

Product Description

The ISCAR 5509557 is a solid carbide replaceable tip drill designed for high-productivity drilling in steel and stainless steel applications. Part of the ICP-2M series, this tip carries an IC908 submicron carbide grade with a PVD-applied TiAlN coating for heat resistance and edge retention. The drill point geometry features a 140-degree included angle with double margin construction and a slow spiral flute configuration. The tip seats into a size 8 insert seat and is held by a twist-style locking method. At 0.327 inches cutting diameter and 0.153 inches functional length, it is suited for precise short-hole drilling operations. Licensed trades machinists and CNC operators install this type of replaceable tip to reduce tooling cost while maintaining consistent hole quality.

This replaceable tip is intended for use in ferrous and difficult-to-machine materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It is classified under ISO workpiece material codes P, M, K, S, and H, making it a versatile option across a range of production drilling applications. The ICP-2M series is typically deployed in CNC machining centers and drill presses where repeatable hole geometry and long tool life are required. The tip conforms to ISO 13399 tooling data standards, simplifying integration into CAM and tool management systems.

Key Features

• PVD TiAlN coating improves heat resistance and reduces built-up edge
• 140-degree drill point angle with double margin geometry for accurate hole entry and exit
• Slow spiral flute design optimized for chip evacuation in steel and stainless steel
• Twist-style insert holding method provides secure seating and repeatable tip positioning
• Conforms to ISO 13399 for seamless tool data integration

Compatibility

Designed as a replaceable tip for ICP-2M series drill bodies accepting a size 8 insert seat. Compatible with workpiece materials classified under ISO codes P (steel), M (stainless steel), K (cast iron), S (super-alloys and titanium), and H (hard materials). Refer to the ISCAR ICP-2M drill body selection guide to confirm body-to-tip compatibility before ordering.

Installation Notes

Installation and replacement of carbide drill tips should be performed by qualified machinists following the tool manufacturer's torque and seating procedures for the specific drill body. Ensure the machine spindle is fully stopped and locked out before changing the tip. Inspect the insert seat for debris, wear, or damage before seating the new tip, as a contaminated or worn seat will affect hole accuracy and may damage the tip. Follow applicable shop safety protocols and machine tool manufacturer guidelines during tool changes.
