Iscar 5508589 Replaceable Drill Tip 0.685 in Carbide IC908

Product Description

The ISCAR 5508589 is a replaceable drill tip engineered for high-performance drilling in demanding materials. Part of the ICM series, this solid carbide tip carries a TiAlN PVD coating and a manufacturer grade of IC908 with a submicron carbide substrate. The cutting diameter is 0.685 inches, the functional length is 0.286 inches, and the overall length is 0.390 inches. The 140-degree drill point angle and T-Land insert geometry are optimized for cutting into stainless steel, superalloys, and titanium without excessive heat buildup or edge wear. A web-thinned point reduces thrust load at entry, improving hole entry accuracy and tool life.

This drill tip is intended for use in CNC machining centers and drilling operations targeting stainless steel, superalloys, and titanium as primary workpiece materials, with secondary capability in steel, cast iron, and hard materials. The insert seat size is 17 and the ISO number is ICM 174. The slow spiral flute type and twist insert holding method make this tip well suited to interrupted cuts and cross-hole applications where chip control and rigidity are critical. It is installed by machinists and tooling technicians working in precision manufacturing, aerospace, medical device fabrication, and general metalworking environments.

Key Features

• Solid carbide construction with submicron grain substrate for hardness and edge integrity under high-temperature cutting conditions
• TiAlN PVD coating extends tool life in stainless steel, superalloys, and titanium by reducing heat absorption at the cutting edge
• 140-degree included angle with T-Land geometry reduces burr formation and improves point stability on entry
• Web-thinned point lowers axial thrust for cleaner hole entry and reduced spindle load
• Slow spiral flute design promotes controlled chip evacuation in difficult-to-machine materials
• Compliant with ISO 13399 tooling data standards for seamless integration with CAM and tool management software

Compatibility

Designed as a replaceable tip for ICM series drill bodies using insert seat size 17. ISO number ICM 174. Verify holder compatibility against the specific ISCAR ICM drill body specification before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body and insert seat are clean and free of chips or debris before seating the tip, as contamination in the insert pocket can cause runout and premature tip failure. Use the torque wrench specified by the tool body manufacturer for the clamping screw - do not overtighten. Index or replace the tip when cutting performance degrades; running a worn replaceable tip risks workpiece damage and insert seat wear on the holder body.
