Iscar 5567928 Replaceable Drill Tip 0.3430 in IC908

Product Description

The ISCAR 5567928 is a replaceable drill tip from the HCP-IQ series, designed for use in modular indexable drill systems. This solid carbide tip features a 0.3430-inch (8.71 mm) cutting diameter, a 134-degree self-centering point angle, and a TiAlN coating applied via PVD process. The IC908 submicron carbide grade delivers toughness and wear resistance when drilling through steel, cast iron, stainless steel, superalloys, and titanium. With two helical flutes and a web-thinned geometry, the tip reduces entry forces and improves chip evacuation. It is sized to Insert Seat Size 8 and is installed and replaced by machinists and tool-crib technicians in production and job-shop environments.

This tip is suited for hole making, chamfering, and general drilling operations in metalworking applications. Primary target materials are steel (ISO P) and cast iron (ISO K), with secondary capability in stainless steel (ISO M), superalloys, titanium, and hard materials (ISO S and H). The HCP-IQ design is intended for moderate-depth drilling where quick tip replacement reduces downtime. It is typically used in CNC machining centers, lathes with live tooling, and dedicated drilling machines running coolant-external setups.

Key Features

• Solid carbide construction with submicron IC908 grade for extended tool life in ferrous materials
• TiAlN coating via PVD process improves heat resistance and wear performance
• 134-degree self-centering point angle reduces walking and eliminates pre-spotting in most applications
• Web-thinned geometry lowers thrust force and improves chip flow
• Two helical flutes with regular spiral for reliable chip evacuation
• Insert Seat Size 8 clamp-held design for fast, repeatable tip changes without removing the drill body

Compatibility

Designed as an OEM-style replaceable tip for HCP-IQ series modular drill bodies sized for Insert Seat Size 8. ISO number reference: HCP 087-IQ. Conforms to ISO 13399 tooling data standards.

Installation Notes

This tip is installed by qualified machinists or tool-crib personnel using the clamp-holding method specified for HCP-IQ series drill bodies. Ensure the machine spindle is fully stopped and the tool is secured in a vise or tool holder before removing or seating the tip. Confirm the seat and tip seating surfaces are clean and free of chips before clamping. Do not use this tip in coolant-through drill bodies requiring internal coolant delivery, as this tip does not support through-coolant flow.
