The adapter features a tap shank diameter of 0.697 inches and a tap square size of 0.523 inches, making it suited for mid-range tap sizes in production tapping operations. With a projection of 2.25 inches and an outside shank diameter of 1.25 inches, the 7716-087 provides rigid, repeatable tap positioning. Machinists and tooling technicians install this adapter as part of a modular quick-change tapping system to reduce setup time and maintain tap alignment during rigid or tension-compression tapping cycles.\u003c\/p\u003e\n\u003cp\u003eThis tapping adapter is intended for use in metalworking environments where production tapping efficiency is critical. It fits into the NUMERTAP 770 Series quick-change tooling system and is appropriate for both vertical and horizontal machining center applications. The adapter accommodates taps within its specified shank and square dimensions and is suited for ferrous and non-ferrous material tapping in job shop and production floor settings. Coolant-through capability is not included in this adapter. Installation is performed by qualified machinists or tooling setup personnel following the machine tool builder and toolholder manufacturer guidelines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTap shank diameter of 0.697 inches for precise tap seating\u003c\/li\u003e\n  \u003cli\u003eTap square size of 0.523 inches to engage tap drive securely\u003c\/li\u003e\n  \u003cli\u003eQuick-change interface for fast tap changeovers without removing the holder from the spindle\u003c\/li\u003e\n  \u003cli\u003eProjection of 2.25 inches provides clearance in deep-hole or obstructed tapping applications\u003c\/li\u003e\n  \u003cli\u003eOutside shank diameter of 1.25 inches for stable, concentric mounting\u003c\/li\u003e\n  \u003cli\u003ePart of the NUMERTAP 770 Series modular tooling system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the PARLEC NUMERTAP 770 Series quick-change tapping system.
