Iscar 5506643 Carbide Replaceable Tip Drill 19mm IC908

Product Description

The ISCAR 5506643 is a solid carbide replaceable tip drill from the ICP series, designed for high-performance hole making in demanding metalworking applications. Manufactured to ISO 13399 standards, it carries the IC908 grade designation, a submicron carbide substrate with a PVD-applied TiAlN coating for heat resistance and extended tool life. The drill tip measures 19mm (0.748 inches) in cutting diameter with an 11mm (0.433 inch) height and a flute length of 8mm. The 140-degree drill point angle and helical, regularly spiraled two-flute geometry promote chip evacuation and accurate entry. This insert is installed and serviced by machining professionals and toolroom technicians working in production or job-shop environments.

This replaceable tip drill is suited for hole making, chamfering, and general drilling operations in steel as its primary workpiece material. It is also rated for secondary materials including stainless steel, cast iron, superalloys, titanium, and hard materials. The P-geometry insert with web-thinned design reduces entry force and is appropriate for both light production runs and moderate-volume drilling cycles. The clamp-style insert holding method provides secure seating in the ICP-series body at insert seat size 19.

Key Features

• IC908 submicron carbide grade with PVD TiAlN coating for wear resistance in steel and hard materials
• 140-degree drill point angle with web-thinned geometry reduces thrust and improves hole entry
• Two-flute helical design with regular spiral for efficient chip removal
• Replaceable tip design allows tip replacement without changing the drill body, reducing tooling cost
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems
• Rated for hole making, chamfering, and drilling across P, M, K, S, and H workpiece material categories

Compatibility

Designed for use with ICP-series replaceable tip drill bodies at insert seat size 19, ISO number ICP 190. Compatible workpiece materials include steel (P), stainless steel (M), cast iron (K), superalloys and titanium (S), and hard materials (H).

Installation Notes

This replaceable tip is installed by trained machinists or toolroom technicians using the clamp-style seating method standard to ICP-series drill bodies. Ensure the machine spindle is fully stopped and the tool body is secured before removing or seating the tip. Inspect the insert pocket and clamping surfaces for chips or debris before installing a new tip. Follow the drill body manufacturer torque and seating guidance for the specific ICP body in use.
