Iscar 5508263 Carbide Replaceable Tip Drill 0.374 in Icp

Product Description

The ISCAR 5508263 is a solid carbide replaceable tip drill in the ICP series, designed for high-productivity hole-making in ferrous and difficult-to-machine materials. It carries a TiAlN coating applied via PVD process, which extends tool life and supports dry or semi-dry cutting conditions. The drill tip features a 140-degree included angle with a thinned point geometry and a honed cutting edge for stable entry and reduced thrust. With a cutting diameter of 0.374 inches and a slow spiral flute configuration, this insert is engineered for controlled chip evacuation in deep-hole applications. Machinists and tooling specialists working on production lines install this tip into compatible ICP-series drill bodies.

This replaceable tip is suited for drilling into steel as its primary workpiece material, with secondary capability in stainless steel, cast iron, super-alloys, titanium, and hard materials. The IC908 grade uses a submicron carbide substrate that resists wear and chipping under interrupted cuts and abrasive conditions. Typical applications include component drilling on CNC machining centers in job shops, general manufacturing, aerospace, and energy sector environments where tool change time and insert cost per hole are closely managed.

Key Features

• TiAlN PVD coating for thermal resistance and extended tool life in steel and stainless steel
• 140-degree thinned point reduces thrust and improves centering on entry
• Honed cutting edge geometry minimizes built-up edge in sticky materials
• Slow spiral flute design supports chip control in moderate-depth holes
• IC908 submicron carbide grade rated for steel, stainless, cast iron, super-alloys, titanium, and hard materials
• Conforms to ISO 13399 tooling data standards for CAM and tool management integration

Compatibility

Designed for use with ISCAR ICP-series drill bodies accepting insert seat size 9, ISO number ICP 095. Confirm body compatibility before ordering.

Installation Notes

Replaceable tip drills are installed and serviced by machinists or tooling technicians on CNC machining centers. Power down and lock out the spindle before removing or seating the tip. Use the correct torque tool as specified by the drill body manufacturer — do not overtighten or substitute hand tools that may damage the seating surface. Inspect the pocket and coolant ports for chips or debris before installing the new tip.
