The Omega Products ER25 Tapping Collet - 10 Micron Run-Out - 5mm x 4mm is engineered for precision tapping in metalworking and machining environments. It’s ideal for engineers, machine shops, tradespeople, and serious hobbyists who require dependable, repeatable tool holding. Its ultra-tight run-out helps keep tapping tools centered, delivering clean threads and consistent performance. When paired with ER25 collet chucks, this collet provides a secure, repeatable grip on tapping tools, minimizing slip and vibration during operation. The 10 micron run-out specification ensures alignment stays true through repeated cycles, helping you maintain tight tolerances across parts. Ultra-low run-out for precise tapping: The 10 micron run-out keeps your tapping tools aligned, reducing deflection and producing more accurate threads with smoother finishes. ER25-compatible tool gripping: Designed to fit standard ER25 collet chucks for dependable clamping, quick tool changes, and consistent performance. Repeatable, reliable results: Tight tolerances and careful machining deliver consistent performance across multiple taps, reducing rework and downtime. With this collet, you gain faster, more confident setups, fewer rejects from misalignment, and longer tool life thanks to reduced chatter and deflection. It supports a wide range of tapping tasks—from small-scale prototypes to production runs—delivering clean threads, tighter tolerances, and improved overall productivity.
