Iscar 5504917 Carbide Replaceable Tip Drill 0.504 in IC908

Product Description

The ISCAR 5504917 is a solid carbide replaceable tip drill insert in the IDI-SG series, designed for high-performance drilling in a wide range of metalworking applications. It carries the IC908 manufacturer grade, a submicron carbide substrate with a PVD-applied TiAlN coating that resists heat and wear during aggressive metal removal. The drill tip features a 140-degree included angle with a thinned web point and slow spiral fluting for controlled chip evacuation. At 0.504 inches cutting diameter and 0.137 inches functional length, this insert is a direct replacement tip for compatible IDI-SG series drill bodies. Total package weight is 0.02 pounds.

This replaceable tip is suited for drilling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO workpiece material codes P, M, K, S, and H. Typical installation scenarios include CNC machining centers and production drilling operations where quick tip replacement reduces downtime compared to indexable or solid shank drills. The general-purpose SG geometry makes it applicable across a broad spectrum of ferrous and exotic metal workpieces commonly encountered in industrial machining environments.

Key Features

• IC908 submicron solid carbide substrate for toughness in interrupted and continuous cuts
• PVD TiAlN coating extends tool life in high-heat drilling of steel and stainless steel
• 140-degree included angle with thinned web point reduces entry force and improves centering
• Slow spiral flute design promotes chip control in deep and through-hole drilling
• Replaceable tip design allows tip swap without removing the drill body from the machine
• Compliant with ISO 13399 tool data standards for integration with CAM and tooling databases

Compatibility

Designed for use with ISCAR IDI-SG series drill bodies accepting insert seat size 12, per ISO number IDI 128-SG. Verify seat size and series designation on the host drill body before installation.

Installation Notes

Installation is performed by machining professionals using the twist-lock holding method specified for IDI-SG series bodies. Power down and de-energize the machine spindle completely before removing or seating the tip insert. Use the correct torque key or wrench supplied or specified by ISCAR for the IDI-SG locking mechanism — do not use improvised tools that can damage the seat or insert. Inspect the insert seat for chips or debris before seating the new tip to ensure full contact and accurate runout.
