Iscar 5508324 Replaceable Drill Tip 0.343 in Carbide

Product Description

The ISCAR 5508324 is a replaceable drill tip designed for high-performance drilling in demanding materials. Built from solid carbide with an IC908 manufacturer grade and submicron material grade, this tip delivers consistent cutting performance in production environments. The TiAlN coating is applied via PVD process, providing thermal resistance and wear protection during aggressive drilling cycles. With a cutting diameter of 0.343 inches and a 140-degree drill point angle, the tip is configured for efficient chip evacuation and reduced thrust force. It is installed by machinists and tooling technicians using compatible modular drill bodies from the ICM series.

This replaceable tip is intended for drilling applications in stainless steel, superalloys, and titanium as its primary workpiece materials. It also performs in steel, cast iron, and hard materials as secondary applications. The slow spiral flute design and web-thinned point type make it well suited for materials that generate heat and work-harden under cutting loads. It is commonly used in aerospace, oil and gas, and precision manufacturing environments where tool change time and consistent hole quality are critical. The T-Land style edge geometry adds stability in interrupted or tough-entry cuts.

Key Features

• Solid carbide construction at IC908 grade with submicron grain structure for edge toughness
• TiAlN PVD coating for heat resistance and extended tool life in hard-to-machine alloys
• 140-degree included angle with web-thinned point for reduced thrust and improved centering
• Slow spiral flute with T-Land geometry optimized for stainless steel, superalloys, and titanium
• Replaceable tip design allows fast indexing without removing the drill body from the machine
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use with ISCAR ICM series modular drill bodies accepting insert seat size 8. ISO number reference: ICM 087.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the drill body and machine spindle are fully stopped and de-energized before handling or replacing the tip. The twist-lock holding method requires proper seating of the tip in the insert seat before applying cutting loads. Inspect the seat and locking mechanism for debris or wear at each tip change to maintain runout accuracy.
