Iscar 5505302 Carbide Replaceable Tip Drill 0.488 in IC908

Product Description

The ISCAR 5505302 is a solid carbide replaceable tip drill from the IDI-SK series, designed for high-productivity hole-making in demanding machining environments. It carries the IC908 submicron carbide grade with a PVD-applied TiAlN coating, delivering strong wear resistance and thermal stability at the cutting edge. The drill features a 0.488-inch cutting diameter, a 140-degree included point angle, and a slow spiral flute design with a thinned web point. It is installed and replaced by CNC machinists and toolroom professionals working on machining centers or drill presses requiring consistent bore quality and repeatable tip indexing.

This replaceable tip is suited for drilling operations in cast iron as its primary workpiece material. It is also rated for use in steel, stainless steel, super-alloys, titanium, and hard materials. The IDI-SK system uses a twist-lock insert holding method, allowing rapid tip exchanges without removing the drill body from the spindle. Typical applications include production drilling in automotive, aerospace, and general metalworking shops where tool change time and per-hole cost are key concerns.

Key Features

• IC908 submicron solid carbide grade with PVD TiAlN coating for extended tool life in cast iron and steel
• 140-degree thinned web point angle reduces thrust force and improves chip formation at entry
• Slow spiral flute geometry supports controlled chip evacuation in short-chipping materials such as cast iron
• Corner chamfer style edge preparation adds cutting edge strength at the periphery
• Twist-lock insert holding method enables fast, repeatable tip replacement without body removal
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems

Compatibility

Designed as a replaceable tip insert for IDI-SK series drill bodies accepting insert seat size 12, conforming to ISO number IDI 124-SK. Verify body series and seat size before ordering.

Installation Notes

Installation and replacement of carbide drill tips should be performed by qualified machinists following the drill body manufacturer's torque and seating procedure. Power down and lock out the spindle before handling any indexable cutting insert. Inspect the insert pocket and seating surfaces for chips or damage before seating the new tip. Do not force the insert; improper seating can cause insert breakage or poor bore geometry.
