Tension-Only & Synchronous (Rigid) Tapping Attachments

---

Tension-Only for Synchronous and Blind Hole tapping on CNC machines. Synchronous (Rigid) tapping on machines with 32 bit microprocessors. Quick-change tap adapters and radial float ensure good tapping quality. For best performance in synchronous tapping cycles, use tension only attachments. These attachments will help eliminate tap elongation, common in synchronous tapping.

From #6 – 1 5/8” Hand and 1/16 – 1 1/4” Pipe

• Tension only (TT) allows synchronous tapping on machines so equipped.
• Solid design with no tension or compression (TR, FS).
• Quick-change tap adapters ensures quick, easy tap changeover.
• Radial float allows tap to follow the hole.
• Large work range maximizes workpiece size and eliminates need to purchase multiple units.
• Short projection.
• Through-spindle coolant option gets coolant into the hole and flushes chips.
• Rugged alloy steel construction for long trouble-free service life.
