Iscar 5505606 Carbide Replaceable Tip Drill 0.843 in

Product Description

The ISCAR 5505606 is a solid carbide replaceable tip drill in the IDI-SG series, designed for high-performance hole-making in demanding metalworking applications. The tip features a TiAlN coating applied via PVD process, a 140-degree included angle with a thinned web point, and a slow spiral flute configuration. The cutting diameter is 0.843 inches (21.41mm), and the tip height is 0.374 inches (9.50mm). The IC908 submicron carbide grade provides wear resistance and edge retention across a range of workpiece materials. Licensed machinists and CNC operators install this tip into compatible IDI-SG insert seat size 21 drill bodies.

This replaceable tip drill is intended for general-purpose drilling operations in both manual and CNC machining environments. The SG insert geometry and IC908 grade make it well suited for production drilling in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is appropriate for job shop and production floor applications where consistent hole quality and repeatable tool life are required. The slow spiral flute aids chip evacuation in tougher materials. This part ships individually and is ordered in multiples of two.

Key Features

• Solid carbide IC908 submicron grade for extended tool life in abrasive and hard workpiece materials
• TiAlN coating via PVD process reduces heat buildup and improves wear resistance
• 140-degree included angle with thinned web point for reduced thrust and improved centering
• Slow spiral flute design promotes chip control in steel, stainless steel, cast iron, superalloys, titanium, and hard materials
• Replaceable tip design allows quick tip changes without removing the drill body from the machine
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use with IDI-SG series drill bodies requiring insert seat size 21. ISO number reference IDI 214-SG. Compatible workpiece materials include steel (P), stainless steel (M), cast iron (K), superalloys and titanium (S), and hard materials (H) per ISO material classification codes.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine spindle before replacing the tip. Use the appropriate torx or clamping key specified for the IDI-SG drill body to secure the replaceable tip; do not overtighten by hand without the correct tool. Verify runout and tip seating before resuming cutting operations.
