Iscar 5508287 Replaceable Drill Tip 0.4373 in IC908

Product Description

The ISCAR 5508287 is a replaceable drill tip from the ICP series, designed for use in modular indexable drill systems. It features a 0.4373-inch (11.10 mm) cutting diameter with a 140-degree point angle and a two-flute helical design. The tip is manufactured from solid carbide using a submicron grade material and carries the IC908 manufacturer grade with a PVD-applied TiAlN coating. The seat size is 11, and the overall projection measures 0.2601 inches. A web-thinned geometry reduces cutting forces at entry. This tip is installed by machinists and tool-and-die professionals in production drilling applications.

This drill tip is intended for hole-making operations in steel as its primary workpiece material. Secondary compatible materials include stainless steel, cast iron, superalloys, titanium, and hard materials. The ICP series tip supports applications such as drilling, chamfering, and gundrills. It conforms to ISO 13399 standards and uses a clamp-style insert holding method. The regular spiral flute type and standard point geometry make it suitable for through-hole and blind-hole work in machining centers and CNC drilling equipment.

Key Features

• Solid carbide construction with submicron grade material for wear resistance in ferrous and hard workpiece materials
• IC908 grade with PVD TiAlN coating for thermal protection and extended tool life
• 140-degree point angle with web-thinned geometry for reduced thrust force at drill entry
• Two-flute helical design for efficient chip evacuation
• Clamp-style seating on insert seat size 11 for repeatable tip indexing
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use in ICP series modular indexable drill bodies that accept seat size 11 replaceable tips. Compatible with ISO number ICP 111 tool bodies. Verify seat size and series designation against the drill body specification before ordering.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tool is removed from the spindle or secured before replacing the tip. Clean the seat pocket and inspect for debris or wear before seating the new tip. Follow the drill body manufacturer torque specification for the clamping screw — do not over-torque, as this can damage the carbide tip or the seat.
