Iscar 5505079 Replaceable Drill Tip 0.315 in Carbide IC908

Product Description

The ISCAR 5505079 is a replaceable drill tip designed for use with modular drilling systems. Manufactured from solid carbide in the IC908 grade with a submicron material grade, this tip delivers consistent cutting performance across a range of demanding workpiece materials. It features a PVD-applied TiAlN coating for heat and wear resistance. The tip measures 0.315 inches in cutting diameter with a functional length of 0.104 inches and an overall length of 0.161 inches. The 140-degree drill point with a thinned web reduces entry force and minimizes walking on initial contact. This part is sized for an insert seat size 8 and belongs to the IDI-SG series.

This replaceable drill tip is suited for drilling operations in steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, S, and H. The slow spiral flute type and SG insert geometry make it a general-purpose drilling insert for both production and maintenance machining environments. It is installed by machining professionals using compatible IDI-series modular drill bodies. The tip is held in place by a twist-locking mechanism and does not require coolant-through capability.

Key Features

• Solid carbide construction with IC908 submicron grade for extended tool life
• PVD TiAlN coating provides heat resistance and reduces built-up edge
• 140-degree included angle with thinned web point for reduced thrust force
• SG insert geometry with slow spiral flutes for controlled chip evacuation
• Covers five ISO material groups: P, M, K, S, and H
• Twist-locking insert holding method for secure, repeatable seating

Compatibility

Designed for use with ISCAR IDI-SG series modular drill bodies accepting insert seat size 8. ISO number IDI 080-SG. Conforms to ISO 13399 tooling data standards.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the drill body is fully secured in the machine spindle and the machine is powered down before replacing the tip. The twist-locking seat should be inspected for debris or damage before seating a new tip. Do not apply excessive force during tip installation, as the twist-lock mechanism is designed to reach full engagement at a defined rotational stop.
