Built to A4E toolholder style standards, it accommodates A4 series inserts with a seat size of 5 and uses a clamp-style insert holding method for secure, repeatable positioning. The toolholder is manufactured from steel and features through-coolant capability, directing fluid directly to the cutting zone to extend insert life and improve chip evacuation during deep internal grooving. With a maximum depth of cut of 0.63 inches and an overall length of 12 inches, this right-hand holder is suited for demanding production environments where consistency and rigidity are required.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is configured for internal grooving applications where access to bores and internal features is required. It requires a minimum hole diameter of 2.047 inches and supports boring depths up to 3.15 inches, making it appropriate for medium to large-bore turning work. The multi-use designation indicates it can handle a range of grooving tasks within compatible setups. It is typically installed by machinists and toolroom technicians working on production lathes in manufacturing, aerospace, oil and gas, and general metalworking environments. Compatible inserts follow the A4..05.. designation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal right-hand grooving configuration with A4E toolholder style\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant delivery for improved chip control and insert longevity\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003eMinimum groove width: 0.197 inches (5.00 mm)\u003c\/li\u003e\n  \u003cli\u003eMinimum hole diameter: 2.047 inches for bore access\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity in high-load turning applications\u003c\/li\u003e\n  \u003cli\u003eMulti-use capable across compatible A4 series insert configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with A4..05.. series inserts.
