Iscar 5509301 Replaceable Drill Tip 0.272 in 140 Deg IC908

Product Description

The ISCAR 5509301 is a replaceable carbide drill tip in the ICP series, designed for indexable drill bodies used in precision hole-making operations. It carries a cutting diameter of 0.2720 inches (7.00 mm) and a 140-degree point angle with a standard point type and web-thinned geometry. The insert is manufactured from submicron solid carbide and coated with TiAlN via a PVD process, providing thermal resistance and edge durability during high-speed drilling. Installed using a clamp-type holding method, this tip is suited for machinists and tooling technicians running CNC or manual machining centers across production environments.

This replaceable tip is intended for steel as its primary workpiece material, with secondary suitability for stainless steel, cast iron, superalloys, titanium, and hard materials. It fits insert seat size 6.5 and belongs to the ICP style family. The two-flute helical design supports chip evacuation in through-hole and blind-hole drilling applications. Typical use cases include production drilling, chamfering, and gundrill-style operations where a consistent, repeatable cutting geometry is required across multiple cycles.

Key Features

• Submicron solid carbide construction for edge retention in demanding materials
• TiAlN coating applied via PVD process for elevated heat and wear resistance
• 140-degree point angle with web-thinned geometry reduces entry thrust
• Two-flute helical flute design supports consistent chip evacuation
• Clamp-type insert holding method for secure, repeatable seating
• Complies with ISO 13399 tooling data standards

Compatibility

Designed for use with ICP-series indexable drill bodies requiring an insert seat size of 6.5. ISO number ICP 069 applies. Verify body and seat size match before installation.

Installation Notes

Installation and replacement of indexable drill tips should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before removing or seating the insert. Use the manufacturer-specified torque wrench for the clamping screw to ensure proper seating without over-torquing. Inspect the insert seat for chips or debris before installing the new tip.
