Iscar 5567343 Carbide Replaceable Tip Drill 0.551 in Hcp-iq

Product Description

The ISCAR 5567343 is a solid carbide replaceable tip drill insert in the HCP-IQ series, designed for high-performance drilling in steel, cast iron, stainless steel, superalloys, titanium, and hard materials. The tip carries an IC908 submicron carbide grade with a PVD-applied TiAlN coating, providing heat resistance and edge retention under demanding cut conditions. At 0.551 inches cutting diameter and a 137-degree included angle with a self-centering point, the insert seats into compatible HCP-IQ drill bodies and delivers consistent hole quality without a pilot hole. Licensed machinists and CNC operators working in job shops, aerospace, and general metalworking are the primary installers.

This replaceable tip is suited for drilling primary workpiece materials classified ISO P (steel) and ISO K (cast iron), with secondary capability in ISO M (stainless steel), ISO S (superalloys and titanium), and ISO H (hard materials). The slow-spiral, 2-flute geometry supports deep-hole applications where chip evacuation and stability matter. The self-centering point geometry eliminates the need for a center-drill operation in most setups, reducing cycle time on CNC machining centers and drill presses running rigid setups.

Key Features

• IC908 submicron carbide grade with PVD TiAlN coating for extended tool life in ferrous and hard materials
• 137-degree self-centering point eliminates center-drilling in most CNC applications
• Slow-spiral 2-flute design supports deep-hole drilling with controlled chip flow
• Web-thinned geometry reduces thrust force at entry
• ISO P geometry insert seat, ISO 13399 compliant for tooling data integration
• Twist-lock insert holding method for repeatable seating in HCP-IQ bodies

Compatibility

Designed for use with compatible HCP-IQ series drill bodies accepting a 14mm insert seat size, ISO number HCP 140-IQ. Verify body seat size and series designation before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing the replaceable tip. Use the correct torx or hex key as specified by the drill body manufacturer to achieve proper clamping torque — do not overtighten or undertighten the twist-lock mechanism. Inspect the insert pocket seat for chips or damage before each tip change to ensure accurate seating and runout.
