Iscar 5505558 Carbide Replaceable Tip Drill 0.827 in Idi-sk

Product Description

The ISCAR 5505558 is a solid carbide replaceable tip drill in the IDI-SK series, designed for high-productivity drilling in demanding industrial applications. The tip features a TiAlN coating applied via PVD process, a 140-degree included angle with a thinned point, and a slow spiral flute configuration with corner chamfer style geometry. The cutting diameter measures 0.827 inches with a functional length of 0.224 inches. At 0.05 pounds, this lightweight insert is handled by machinists and toolroom technicians working on CNC and manual drilling operations requiring consistent, repeatable hole quality.

The 5505558 tip is engineered primarily for cast iron workpieces and is rated for secondary use in steel, stainless steel, super-alloys, titanium, and hard materials. The slow spiral design manages chip evacuation in short-chipping materials like cast iron, while the corner chamfer geometry reduces edge loading at drill entry. This tip seats into IDI-SK compatible drill bodies using a twist-lock holding method and conforms to ISO 13399 tooling data standards. It is suited for job shop, production machining, and maintenance environments where interchangeable tip drills reduce downtime during tip changes.

Key Features

• TiAlN PVD coating provides heat resistance and wear protection in ferrous and hard materials
• 140-degree thinned point reduces thrust force and improves self-centering on entry
• Slow spiral flute geometry optimized for chip control in cast iron and short-chipping materials
• Corner chamfer insert geometry (K) reduces chipping at the cutting edge
• Twist-lock seating method enables fast, repeatable tip indexing without special tools
• Conforms to ISO 13399 for standardized tooling data integration

Compatibility

Designed for use with IDI-SK series drill bodies accepting insert seat size 21. Compatible with systems requiring ISO number IDI 210-SK. Verify body seat size before ordering.

Installation Notes

Installation of replaceable tip drills should be performed by qualified machinists following the tool manufacturer's seating and torque guidelines for the specific drill body. Ensure the drill body bore and seating surfaces are clean and free of chips before inserting the tip. Power down and lock out the spindle before tip changes on any machine tool. Do not exceed the rated cutting parameters for the workpiece material group being machined.
