Iscar 5506274 Carbide Replaceable Tip Drill Idi-sg

Product Description

The ISCAR 5506274 is a carbide replaceable tip drill in the IDI-SG series, designed for high-performance drilling in metalworking applications. The drill tip measures 1.012 inches (25.7 mm) in cutting diameter and 11 mm in height, with a 140-degree included angle and a thinned drill point for reduced thrust and improved center cutting. The solid carbide tip carries the IC908 manufacturer grade, a submicron-grain carbide substrate coated with TiAlN via a PVD process. This combination delivers heat resistance and edge retention when cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Installation is performed by qualified machinists or toolroom technicians as part of a replaceable tip drill body system.

The 5506274 tip is intended for use in IDI-SG series drill bodies with an insert seat size of 25. The two-flute, slow-spiral design with spiral flute geometry suits general-purpose drilling operations on a wide range of metallic workpiece materials, including P, M, K, S, and H material classification grades per ISO standards. This tip is well suited for production machining environments in job shops, aerospace, energy, and general manufacturing where consistent hole quality and quick tip replacement without regrinding are priorities.

Key Features

• Solid carbide IC908 grade tip with submicron-grain substrate for edge retention in hard and abrasive materials
• TiAlN PVD coating for thermal resistance and extended tool life in steel and stainless steel
• 140-degree included angle with thinned point reduces cutting forces and improves drill entry
• Slow-spiral, two-flute design promotes chip evacuation in general-purpose drilling
• Replaceable tip design reduces tooling cost compared to solid drill replacement
• Compliant with ISO 13399 tooling data standards

Compatibility

Designed for use with ISCAR IDI-SG series replaceable tip drill bodies requiring insert seat size 25. ISO number IDI 257-SG. Verify body seat size and series before ordering.

Installation Notes

This replaceable tip is installed by a machinist or toolroom technician using the twist-lock holding method specified for IDI-SG series bodies. Ensure the drill body and tip seat are clean and free of chips or burrs before seating the tip. Do not exceed the clamping method specified by the drill body manufacturer. Follow all applicable shop safety procedures and machine lockout protocols before changing cutting inserts.
