Iscar 5509951 Carbide Replaceable Tip Drill 0.315 in

Product Description

The ISCAR 5509951 is a carbide replaceable tip drill in the FCP series, designed for precision drilling in metalworking applications. Built with a solid carbide tip in grade IC908 submicron material, this drill delivers consistent hole quality in demanding production environments. The tip features a TiAlN finish applied via PVD coating, a 140-degree included angle, a thinned web point, and a slow spiral flute configuration. The flat bottom style and two-flute geometry support controlled chip evacuation. Cutting diameter is 0.315 inches with a functional length of 0.130 inches. Machining professionals and tooling technicians install this part in CNC drilling operations requiring repeatable, close-tolerance results.

This replaceable tip drill is suited for drilling steel and cast iron as primary workpiece materials, with secondary capability in stainless steel, super-alloys, titanium, and hard materials. The ISO material group designations are P and K for primary, and M, S, and H for secondary. It fits applications where a replaceable carbide tip format reduces tooling cost versus solid drill replacement. The FCP series tip seats in an insert seat size 8 holder using a twist holding method. The ISO number for this tip is FCP 080. This tool is specified to ISO 13399 standards, making it compatible with modern tooling data systems used in CAM and presetter environments.

Key Features

• Solid carbide IC908 submicron grade tip for wear resistance in ferrous materials
• TiAlN PVD coating resists heat and extends tool life in steel and cast iron
• 140-degree thinned web point reduces thrust force at drill entry
• Slow spiral two-flute design supports chip control in short-chipping materials
• Flat bottom geometry for applications requiring minimal exit burr
• ISO 13399 compliant for integration with digital tooling management systems

Compatibility

Designed for use with ISCAR FCP series replaceable tip drill holders accepting insert seat size 8, ISO number FCP 080, using the twist holding method. Specific holder compatibility should be confirmed with ISCAR tooling documentation prior to ordering.

Installation Notes

Installation of replaceable carbide drill tips should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and energy isolated per lockout/tagout procedures. Use the appropriate ISCAR torque key or installation tool specified for FCP series holders — do not use improvised tools that may damage the seating surface. Inspect the insert seat for chips, debris, or wear before seating the new tip. Confirm runout after installation before initiating a cutting cycle.
