Iscar 5505076 Carbide Replaceable Tip Drill 0.646 in

Product Description

The ISCAR 5505076 is a solid carbide replaceable tip drill from the IDI-SG series, designed for high-precision hole-making in demanding metal-cutting applications. The tip features an IC908 submicron carbide grade with a PVD-applied TiAlN coating, delivering wear resistance and thermal stability at elevated cutting speeds. The drill point is ground to a 140-degree included angle with web thinning for reduced thrust force and improved chip formation at entry. With a cutting diameter of 0.646 inches and a functional length of 0.194 inches, this tip mounts into a compatible IDI-SG series drill body. Licensed HVAC techs, machinists, and toolroom professionals working in production or maintenance environments rely on this geometry for consistent hole quality across multiple material groups.

This replaceable tip is suited for drilling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. The IDI-SG replaceable tip system allows tip changes without removing the drill body from the spindle, reducing downtime in production environments. The slow spiral flute design and SG insert geometry are optimized for general-purpose drilling where a stable, repeatable entry and exit are required. This tip is sold individually with a minimum order quantity of 2 units.

Compatibility

Designed for use with compatible IDI-SG series drill bodies accepting insert seat size 16. The ISO number for this tip is IDI 164-SG. Confirm body compatibility with the seat size and series designation before ordering.

Installation Notes

Replaceable tip installation should be performed by a qualified machinist or toolroom technician familiar with indexable tooling systems. The spindle must be at a complete stop and the machine must be locked out before tip removal or installation. Use the manufacturer-specified torque tool for the twist-lock holding method to ensure proper seating. Do not exceed the recommended cutting parameters for the workpiece material group being machined.
