Iscar 5509117 Carbide Replaceable Tip Drill 0.843 in IC908

Product Description

The ISCAR 5509117 is a carbide replaceable tip drill in the ICM series, designed for precision hole-making in demanding workpiece materials. The cutting tip is manufactured from solid carbide with an IC908 submicron-grade substrate and a TiAlN coating applied via PVD process. The 140-degree included angle with a thinned point and T-Land style geometry reduces cutting forces and improves centering at entry. At 0.843 inches cutting diameter with a functional length of 0.390 inches, this drill tip is suited for high-productivity drilling operations where insert replaceability reduces downtime compared to solid-shank alternatives. Licensed machinists and CNC operators install this style of replaceable tip in compatible ICM series drill bodies.

This replaceable drill tip is engineered for primary use in stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material codes M and S. Secondary applications include steel, cast iron, and hard materials (ISO codes P, K, and H). The slow spiral flute type and web-thinned point geometry are well suited to materials that generate high cutting heat or resist chip evacuation, making this tip a practical choice for aerospace, medical, and heavy industrial machining environments where material toughness is a consistent challenge.

Key Features

• Solid carbide IC908 submicron-grade tip for elevated wear resistance in hard and high-temperature materials
• TiAlN coating via PVD process improves thermal barrier performance during high-speed cutting
• 140-degree included angle with thinned point reduces thrust force and improves drill entry stability
• T-Land cutting edge style provides added edge strength when drilling stainless steel, superalloys, and titanium
• Slow spiral flute geometry aids chip control in tough, stringy, or work-hardening materials
• Replaceable tip design allows fast tip changes on the drill body without disturbing the setup

Compatibility

Designed for use with compatible ISCAR ICM series drill bodies accepting insert seat size 21 and ISO number ICM 214. Verify body seat size and series designation before ordering to ensure proper seating and clamping torque.

Installation Notes

Replaceable tip drills in this series are installed and removed by a licensed machinist or CNC operator following the drill body manufacturer's seating and torque procedure. Ensure the machine spindle is fully stopped and the machine is locked out before handling the tip. Inspect the drill body seat for chips, damage, or wear before installing a new tip, as a contaminated or worn seat will affect runout and tip retention. Do not force the tip into the seat or use impact tools during installation.
