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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHAI 19 style toolholder in the Heliface series for internal non-face grooving\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with clamp-style insert retention\u003c\/li\u003e\n\u003cli\u003eThrough-coolant port directs fluid to the cutting edge for improved chip evacuation\u003c\/li\u003e\n\u003cli\u003e0.75-inch shank diameter and 5.0-inch overall length for internal bore applications\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for CAM system integration\u003c\/li\u003e\n\u003cli\u003eCenter to cutting edge offset of 0.005 inches for precise depth positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or primary toolholder for CNC turning centers and lathes configured for internal grooving with HAI-series Heliface indexable inserts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.
