Iscar 5566705 Carbide Replaceable Tip Drill 0.248 in

Product Description

The ISCAR 5566705 is a solid carbide replaceable tip drill insert designed for precision hole-making in demanding industrial machining applications. Part of the ICP series, this insert features a 0.248-inch cutting diameter and a 140-degree included point angle with web thinning for improved centering and reduced thrust. The TiAlN coating is applied via PVD process, delivering strong oxidation resistance and hardness retention at elevated cutting temperatures. With a slow spiral flute design and honed cutting edge, it is engineered for controlled chip evacuation and consistent hole quality. Machinists and toolroom professionals working with CNC machining centers will find this insert a direct fit for compatible ICP drill bodies.

This replaceable tip insert is suited for drilling operations in steel as its primary workpiece material, with secondary capability in stainless steel, cast iron, super-alloys, titanium, and hard materials. The IC908 grade is a submicron carbide grade optimized for versatility across these material groups. It is commonly used in production machining environments where insert changeability reduces downtime compared to solid drill replacement. Typical applications include through-hole and blind-hole drilling on horizontal and vertical machining centers in metalworking shops and manufacturing facilities.

Key Features

• 0.248-inch cutting diameter with 140-degree thinned point angle for accurate entry and reduced thrust load
• TiAlN coating via PVD process provides heat and wear resistance across a wide range of workpiece materials
• IC908 submicron carbide grade supports steel, stainless steel, cast iron, super-alloys, titanium, and hard materials
• Slow spiral, 2-flute design promotes controlled chip flow in short-chipping and long-chipping materials
• Honed cutting edge finish improves edge stability and reduces micro-chipping during interrupted cuts
• Web-thinned point geometry reduces centering force and improves drill entry consistency

Compatibility

Designed for use with compatible ICP series replaceable tip drill bodies accepting an ICP 063 ISO insert designation with an insert seat size of 6. Confirm body model and seat size before ordering to ensure proper fit and clamping engagement.

Installation Notes

Installation of replaceable tip drill inserts should be performed by a qualified machinist or toolroom technician with the spindle fully locked out and the machine powered down. Use the manufacturer-specified torx or clamping key to seat the insert; do not use improvised tools that may damage the seating surface or holding mechanism. Inspect the insert pocket for wear, debris, or damage before each insert change. Follow applicable shop safety procedures and machine tool manufacturer guidelines for tooling changeouts.
