Iscar 5566716 Carbide Replaceable Tip Drill 0.264 in Tialn

Product Description

The ISCAR 5566716 is a solid carbide replaceable tip drill designed for precision hole-making in demanding materials. It carries the IC908 grade designation with a TiAlN coating applied via PVD process, making it suited for cutting stainless steel, superalloys, and titanium. The cutting diameter is 0.264 inches, the drill point features a 140-degree included angle with a thinned web point, and the spiral configuration is a slow spiral with a T-Land style geometry. With two flutes and a web-thinned construction, this tip delivers controlled chip flow and reduced thrust in difficult-to-machine workpiece materials. Licensed machinists and tool-room technicians working in high-production or job-shop environments are the primary installers and users of this tooling.

This replaceable tip is part of the ICM series and corresponds to ISO number ICM 067. It is intended for drilling operations in ferrous and non-ferrous aerospace and industrial alloys, including stainless steel, superalloys, titanium, steel, cast iron, and hard materials. The submicron carbide substrate combined with the IC908 grade targets applications where tool life and edge stability in heat-generating cuts are critical. The functional length is 0.118 inches and the overall height or projection is 0.169 inches, making this a compact tip for insert-seat size 6.5 compatible tool bodies. This tip ships as a single unit and is subject to a minimum order quantity of 2.

Key Features

• Solid carbide IC908 grade with submicron substrate for edge stability in hard and abrasive materials
• TiAlN coating via PVD process for heat resistance and extended tool life in stainless steel, superalloys, and titanium
• 140-degree drill point angle with web-thinned, thinned-point geometry to reduce thrust force at entry
• Slow spiral, two-flute configuration with T-Land style for controlled chip evacuation
• Conforms to ISO 13399 tooling data standards for compatibility identification
• Compact profile: 0.264 inch cutting diameter, 0.118 inch functional length, 0.169 inch overall height

Compatibility

Designed as a replaceable tip for ICM series tool bodies accepting insert seat size 6.5, per ISO number ICM 067. Compatible primary workpiece materials include stainless steel, superalloys, and titanium (ISO material codes M and S). Secondary workpiece materials include steel, cast iron, and hard materials (ISO material codes P, K, and H). Specific tool body compatibility should be verified against ISCAR ICM series toolholder documentation.

Installation Notes

Replaceable carbide drill tips require a correctly sized and undamaged tool body seat before installation. Ensure the machine spindle is fully stopped and locked out before tip removal or installation. Use the appropriate torque wrench or insert key specified for the ICM series holder to seat the tip securely without over-torquing the carbide. Inspect the insert seat for chips or debris that could affect seating and runout before each tip change.
