Iscar 5567953 Replaceable Drill Tip 0.4689 in IC908

Product Description

The ISCAR 5567953 is a replaceable drill tip from the HCP-IQ series, designed for use with compatible indexable drill bodies in precision hole-making applications. This solid carbide insert features a 0.4689-inch (11.90 mm) cutting diameter, a 139-degree self-centering point angle, and a TiAlN coating applied via PVD process. The IC908 submicron carbide grade delivers high wear resistance and edge stability. Seat size 11 and the HCP-IQ insert geometry ensure repeatable positioning and secure clamping. Licensed machinists and tooling specialists install this tip as a direct consumable replacement in indexable drill assemblies used on CNC turning centers and machining cells.

This drill tip is suited for drilling and chamfering operations primarily in steel and cast iron, with secondary capability in stainless steel, superalloys, titanium, and hard materials. The two-flute helical design with web thinning supports efficient chip evacuation in through-hole and blind-hole applications. Typical use scenarios include high-volume production drilling on CNC machining centers where rapid tip replacement without full tool changes reduces cycle time. Applications also include gundrilling setups where indexable tip systems are used to improve consistency across runs.

Key Features

• Solid carbide IC908 submicron grade for wear resistance in ferrous and difficult-to-machine materials
• TiAlN coating via PVD process improves heat resistance and tool life in high-speed cutting
• 139-degree self-centering point angle reduces walking and promotes accurate hole entry
• Web-thinned geometry supports improved chip flow and reduced thrust force
• Two-flute helical design compatible with HCP-IQ series indexable drill bodies
• ISO 13399 compliant geometry data for use with tooling management and CAM systems

Compatibility

Designed for use with HCP-IQ series indexable drill bodies requiring an insert seat size 11. ISO number reference HCP 119-IQ. Verify seat size and series compatibility with the drill body before installation.

Installation Notes

Replaceable drill tips of this type are installed and serviced by machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is locked out before handling any indexable insert. Clean the insert seat of chips and debris before seating the tip, and inspect the clamp and seat for wear or damage. Follow the drill body manufacturer torque specification for the clamping screw — do not use an impact driver on insert clamp hardware.
