Iscar 5509572 Carbide Replaceable Tip Drill 0.421 in IC908

Product Description

The ISCAR 5509572 is a solid carbide replaceable tip drill designed for high-performance hole-making operations in metalworking applications. Part of the ICP-2M series, this insert features a 0.421 inch cutting diameter, a 140-degree drill point angle, and a TiAlN coating applied via PVD process. The IC908 submicron carbide grade delivers wear resistance and edge stability in demanding cutting conditions. The double-margin point geometry and slow spiral flute design support accurate hole entry and chip evacuation. Machinists and tooling technicians working in production or job-shop environments install this tip into compatible ICP-2M drill bodies as a cost-effective alternative to regrinding solid drills.

This replaceable tip drill is suited for drilling steel as its primary workpiece material, with rated capability in stainless steel, cast iron, super-alloys, titanium, and hard materials. The double-margin style provides enhanced hole straightness and surface finish in through-hole and blind-hole drilling. The web-thinned geometry reduces thrust force at entry. With two spiral flutes and a twist-style insert holding method, the tip seats securely in the ICP-2M body for repeatable runout. This part is manufactured to ISO 13399 standards, making tooling data compatible with CAM and tool management systems. ISO number reference is ICP 107-2M.

Key Features

• 0.421 inch cutting diameter with 140-degree included angle for aggressive, accurate penetration
• IC908 submicron solid carbide grade with PVD-applied TiAlN coating for extended tool life
• Double-margin point style improves hole straightness and reduces surface deviation
• Web-thinned geometry lowers entry thrust and reduces heat generation at the drill tip
• Slow spiral, two-flute design aids chip flow in steel and difficult-to-machine alloys
• Manufactured to ISO 13399 standards for compatibility with digital tooling data systems

Compatibility

Designed for use with ICP-2M series replaceable tip drill bodies accepting insert seat size 10. ISO number ICP 107-2M. Compatible workpiece materials include steel (P), stainless steel (M), cast iron (K), super-alloys and titanium (S), and hard materials (H) per ISO material classification.

Installation Notes

Installation of replaceable carbide tip drills should be performed by a qualified machinist or tooling technician with the machine powered off and spindle locked. Use the correct torx or clamping key specified for the ICP-2M body to seat the tip fully before torquing. Inspect the insert pocket for chips or damage before each tip change. Do not exceed the cutting parameters recommended for the IC908 grade and workpiece material combination.
