Iscar 5509158 Carbide Replaceable Tip Drill 0.921 in Icm

Product Description

The ISCAR 5509158 is a replaceable-tip carbide drill insert belonging to the ICM series, designed for high-productivity hole-making in demanding materials. Manufactured from submicron solid carbide with IC908 grade designation, it carries a PVD-applied TiAlN coating for extended tool life and heat resistance. The tip features a 140-degree included angle with a thinned web point and slow-spiral, T-Land geometry to reduce entry forces and improve chip evacuation. Cutting diameter is 0.921 inches with a functional length of 0.384 inches. This insert is intended for use by machinists and tooling specialists working in production or job-shop environments.

The ICM0921 IC908 tip is optimized for primary use in stainless steel, superalloys, and titanium, material codes M and S per ISO classification. Secondary applications include steel, cast iron, and hard materials, material codes P, K, and H. The ICM series replaceable-tip system is suited for CNC machining centers and turning centers where quick tip changes without full drill body replacement reduce downtime. It is a practical choice for aerospace, energy, and general precision machining operations where difficult-to-cut materials are common.

Key Features

• Submicron solid carbide construction with IC908 manufacturer grade for toughness and wear resistance
• PVD TiAlN coating provides thermal protection and extended edge life in high-temperature alloys
• 140-degree thinned web point reduces thrust force during entry into hard and stainless workpieces
• Slow-spiral, T-Land flute geometry promotes controlled chip flow in gummy and stringy materials
• 2-flute design with twist insert holding method for secure, repeatable seating in ICM-series bodies
• Conforms to ISO 13399 tooling data standards for CAM and tool management system integration

Compatibility

Designed for use with ICM-series replaceable-tip drill bodies accepting insert seat size 23, ISO number ICM 234. Verify body seat size and series designation before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body is fully secured in the spindle and the machine is in a safe, locked-out state before seating or removing the tip insert. Use the manufacturer-specified torque tool for the twist-lock insert holding mechanism to ensure proper clamping without over-torquing the carbide tip. Inspect the insert seat for chips or debris before each installation to maintain runout accuracy.
