It accepts a clamp-style insert holding method and is compatible with DGN, GRIP, and HFPR insert families, giving machinists broad insert selection for grooving and parting operations. The shank measures 1.2500 inches in both height and width, with an overall length of 5.6700 inches. Through-coolant capability is built in, directing fluid directly to the cutting zone to manage heat and extend insert life in demanding turning applications. The toolholder weighs 2.66 pounds and conforms to ISO 13399 standards for cutting tool data representation.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for CNC turning centers and engine lathes requiring reliable grooving and cut-off performance. The right-hand orientation and HAP-style design position it for standard front-tool-post configurations. Compatible insert geometries cover a range of groove widths and profiles, making this holder applicable across general-purpose turning, part separation, and external grooving work in production and job-shop environments. It is used by machinists and tooling setup technicians working with ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRight-hand HAP-style holder for external grooving and cut-off operations\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention for secure, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant delivery directs fluid to the cutting edge for thermal control\u003c\/li\u003e\n  \u003cli\u003e1.2500 inch square shank fits standard turning center tool blocks\u003c\/li\u003e\n  \u003cli\u003eCompatible with DGN, GRIP, and HFPR insert families across multiple size designations\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 cutting tool data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible inserts include DGN 4003C, DGN 4803C, DGN 5003C, GRIP 4002Y, GRIP 4004Y, GRIP 4020Y, GRIP 476-080Y, GRIP 476-238Y, GRIP 5005Y, GRIP 5008Y, GRIP 5025Y, GRIP 6030Y, HFPR 3003, HFPR 3015, HFPR 4004, HFPR 4020, HFPR 5004, HFPR 5025, HFPR 6004, and HFPR 6030.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or tooling technician.
