Iscar 5509955 Carbide Replaceable Tip Drill 0.394 in

Product Description

The ISCAR 5509955 is a carbide replaceable tip drill from the FCP series, designed for precision drilling in metalworking applications. The cutting tip is manufactured from solid carbide in the IC908 submicron material grade and features a TiAlN coating applied via PVD process. The drill has a 0.394 inch cutting diameter, a 140-degree drill point angle, and a slow spiral, flat-bottom flute geometry with web thinning. This insert-style drill is used primarily by machinists and toolroom technicians in CNC and production drilling environments where consistent hole quality and tip replaceability reduce tooling cost.

This replaceable tip drill is suited for production drilling in steel and cast iron as primary workpiece materials, identified under ISO material codes P and K. Secondary workpiece material compatibility includes stainless steel, super-alloys, titanium, and hard materials under ISO codes M, S, and H. The flat-bottom point style and web-thinned geometry make it well suited for accurate entry and exit in interrupted or solid-material drilling operations. It is sized to the FCP 100 ISO number and fits insert seat size 10.

Key Features

• Solid carbide IC908 submicron grade tip for extended wear resistance in ferrous materials
• TiAlN coating via PVD process reduces heat buildup and improves tool life in steel and cast iron
• 140-degree included angle with web-thinned point for clean entry and reduced thrust force
• Flat-bottom, slow spiral flute design supports controlled chip evacuation
• Replaceable tip design minimizes downtime and lowers per-hole tooling cost
• Conforms to ISO 13399 tooling data standards for compatibility with digital tool management systems

Compatibility

Designed as an OEM-style replaceable tip for ISCAR FCP series drill bodies sized to insert seat size 10, ISO number FCP 100. Confirm body seat size before ordering.

Installation Notes

Replaceable tip drills in the FCP series are installed and removed by twisting the tip into the drill body seat. Ensure the drill body is clean and free of chips or debris before seating the tip. Always power down and lockout the machine spindle before changing the insert tip. Follow the machine tool manufacturer torque and clamping guidelines for the specific drill body in use.
