🔥 KEY FEATURES & BENEFITS

✅ Floating retractable compensation – 10–12 mm stroke
effectively reduces stress on the tap during reverse rotation.
✅ Extends tap life by up to 85% – greatly improves efficiency.
✅ Torque overload protection – prevents tap breakage, reduces costs.
✅ Quick & easy clamping – simple loading/unloading.
✅ Dual protection – extends tap life and enhances safety.
✅ High concentricity – bore accuracy after tapping: 0.1 mm.
✅ High-hardness steel – quenched and hardened.
✅ Inner & outer precision grinding – stable, reduces runout.
✅ Smooth, corrosion-resistant surface – fine craftsmanship.
✅ Easy to operate – user-friendly design.

🏗️ MATERIAL & HEAT TREATMENT

🔸 20CrMnTi steel – fully carburized and quenched.
🔸 Inner & outer diameter grinding – enhances wear resistance.
🔸 High-temperature quenching – increases hardness.
🔸 Core toughness retained – maintains low-carbon steel toughness.

⚙️ TORQUE OVERLOAD TAPPING COLLET
