Iscar 5507956 Replaceable Drill Tip 0.5 in Carbide Tialn

Product Description

The ISCAR 5507956 is a replaceable drill tip designed for high-performance drilling in demanding production environments. Built from solid carbide in the IC908 submicron grade, this tip delivers consistent cutting performance across a broad range of workpiece materials. It carries a PVD-applied TiAlN coating that extends tool life under the elevated temperatures common in steel and stainless steel drilling. The 0.5-inch cutting diameter and a 140-degree included angle make it well-suited for moderate-feed, precision-entry applications. The honed cutting edge geometry reduces built-up edge and promotes clean hole entry. This tip is installed and serviced by machinists and tool-room technicians in CNC drilling and turning-center operations.

The 5507956 belongs to ISCAR's ICP series of replaceable drill tips, which pair with compatible drill bodies using a twist insert-holding method. The ISO number ICP 127 identifies the seat interface for matching this tip to the correct body. It is primarily intended for drilling steel but is rated for secondary use on stainless steel, cast iron, super-alloys, titanium, and hard materials. Typical applications include through-hole and blind-hole drilling in automotive, aerospace, and general metalworking production. No coolant-through capability is present on this tip; external or flood coolant delivery is the appropriate cooling method.

Key Features

• Solid carbide IC908 submicron grade for wear resistance in steel and difficult-to-machine alloys
• PVD TiAlN coating reduces thermal wear and extends tool life in dry or flood-coolant operations
• 140-degree drill point angle with web-thinned and honed cutting edge for reduced thrust force and clean entry
• Slow spiral flute type supports chip evacuation in deeper-hole drilling cycles
• ICP 127 ISO interface for repeatable, tool-free tip replacement on compatible drill bodies
• Meets ISO 13399 tool data standards for compatibility with digital tool management systems

Compatibility

Designed for use with ISCAR ICP series drill bodies that accept insert seat size 12 and the ICP 127 twist-style interface. Verify body compatibility using the ISO 13399 tool data designation before installation.

Installation Notes

Installation and replacement of carbide drill tips should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before removing or seating the tip. Use the correct torque key or drive tool specified for the ICP body; never use impact tools or improvised drivers on the twist interface. Inspect the insert seat for chips, debris, or corrosion before seating the new tip, as contamination at the interface can cause tip run-out or premature fracture.
