Iscar 2500422 Grooving Toolholder Hai 19 Internal Rh

Product Description

The ISCAR 2500422 is an indexable internal grooving toolholder built to the HAI 19 style in the Heliface series. Designed for right-hand cutting direction, it accepts indexable inserts secured by a clamp-style holding method. The shank diameter measures 0.75 inches with an overall length of 5.0 inches, making it suited for boring bar-style internal grooving operations. A through-coolant passage delivers cutting fluid directly to the insert tip, supporting chip evacuation and extended insert life in deep-bore or interrupted-cut applications. This toolholder is manufactured to ISO 13399 standards, ensuring consistent data exchange with CAM and tool management systems. It is not configured as a multi-use or face-grooving tool.

This toolholder is intended for internal non-face grooving operations on CNC turning centers and lathes. The right-hand cutting orientation and 0.75-inch shank diameter suit a wide range of internal groove diameters where bore access and coolant delivery are critical. Typical applications include groove turning in steel, cast iron, and similar materials where dimensional accuracy and chip control are priorities. The through-coolant feature makes it especially practical for deep internal features where flood coolant cannot reach the cutting zone directly.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing or seating the toolholder. Verify coolant line connections are secure and free of obstructions before resuming through-coolant operation. Confirm insert seating and clamp torque per the insert manufacturer specifications before taking a cut.
