Iscar 5504854 Carbide Replaceable Tip Drill 0.453 in IC908

Product Description

The ISCAR 5504854 is a solid carbide replaceable tip drill insert in the IDI-SG series, designed for high-performance drilling in demanding metal-cutting applications. The insert carries the IC908 manufacturer grade, a submicron carbide substrate applied with a PVD TiAlN coating for extended tool life at elevated cutting temperatures. The 140-degree included drill point angle is web thinned to reduce entry forces and improve chip evacuation. With a cutting diameter of 0.453 inches (29/64 inch) and a functional length of 0.134 inches, this tip seats into compatible IDI-SG insert seat size 11 drill bodies. Installation is performed by machining and toolroom professionals.

This replaceable tip is suited for drilling operations in steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO workpiece material codes P, M, K, S, and H. It is a general-purpose style insert appropriate for production drilling on CNC machining centers, lathes with live tooling, and dedicated drilling machines where consistent hole quality and repeatable tip indexing are required. The slow spiral flute geometry and thinned point support stable performance across this broad material range without coolant-through capability.

Key Features

• Solid carbide IC908 submicron grade substrate for wear resistance in hard and abrasive materials
• PVD TiAlN coating reduces heat buildup and extends cutting edge life
• 140-degree web-thinned drill point lowers thrust force and improves chip breaking at entry
• Slow spiral, 2-flute design supports controlled chip flow in a wide range of metals
• Conforms to ISO 13399 tooling data standards for integration with CAM and tool management systems
• Replaceable tip design allows quick tip changes without removing the drill body from the machine

Compatibility

Designed for use with IDI-SG series drill bodies accepting insert seat size 11. ISO number reference IDI 115-SG. Verify seat size and series designation on the drill body before ordering.

Installation Notes

Replaceable tip drills are installed and indexed by qualified machinists or toolroom technicians following the drill body manufacturer torque and seating procedure. Power down and lock out the spindle before changing the tip insert. Ensure the insert seat is clean and free of chips or debris before seating the new tip to achieve proper runout and prevent premature insert failure. Always confirm correct insert seat size and series compatibility before installation.
