Iscar 5508387 ICM0476 IC908 Carbide Tip Drill 0.476 in

Product Description

The ISCAR 5508387 is an ICM-series replaceable carbide tip drill designed for high-performance hole-making in demanding workpiece materials. The tip carries ISCAR grade IC908, a submicron solid carbide grade applied with a PVD-deposited TiAlN coating for heat resistance and extended tool life. The 140-degree included point angle with web thinning and a T-Land geometry reduces entry thrust and improves centering. A slow spiral flute design and twist-style tip retention keep the insert locked securely in the drill body during the cut. With a cutting diameter of 0.476 inches and a functional length of 0.276 inches, this tip is sized for ICM seat size 12 drill bodies.

This replaceable drill tip is intended for use in metal-cutting operations across manufacturing, machining, and fabrication environments. Primary target materials include stainless steel, superalloys, and titanium (ISO material groups M and S). It also performs in steel, cast iron, and hard materials (ISO groups P, K, and H). Typical applications include CNC vertical and horizontal machining centers performing through-hole and blind-hole drilling operations. This tip is part of ISCAR Series ICM and conforms to ISO 13399 standards for cutting tool data representation.

Key Features

• IC908 submicron solid carbide grade with PVD TiAlN coating for wear and heat resistance
• 140-degree included angle with web-thinned point for reduced thrust and accurate entry
• T-Land insert geometry suited for interrupted cuts and work-hardening materials
• Slow spiral flute design for controlled chip evacuation in tough alloys
• Twist-style tip retention seats securely in ICM series drill bodies
• Conforms to ISO 13399 cutting tool data standards

Compatibility

Designed for use with ISCAR ICM series drill bodies using insert seat size 12. Compatible ISO material groups include M (stainless steel, superalloys), S (titanium, superalloys), P (steel), K (cast iron), and H (hard materials).

Installation Notes

Replaceable carbide drill tips are installed and removed by machinists or toolroom technicians using the appropriate ISCAR torx or wrench key specified for the ICM drill body. Ensure the drill body seat is clean and free of chips or debris before seating the tip, as contamination can cause tip movement or premature failure. Always power down and lock out the spindle before changing tips. Follow the drill body manufacturer torque guidance for the clamping screw rather than applying general torque values.
