6-piece crimping tool drill bit set, manual copper pipe crimping tool drill bit - Bearing steel drill bit expander with 7/8", 3/4", 5/8", 1/2", 3/8", 1/4" bits

[Function] Forged torch/bucket to ensure a universal coupling that also protects pipes from breakage, primarily for expanding copper pipes. During air conditioning installation, the two copper pipes are tightly connected, offering high resistance to contact fatigue and long-term use, making them less prone to deformation. I believe they can bring convenience to your life.

[High-Quality Materials] The manual copper tail expander is made of practical and durable roller bearing steel. The torch size is always consistent, making it very suitable. It's not easy to drop the hand tool, operation is safer, and the countertop has the perfect depth for close cooperation. Exquisite craftsmanship, a smooth and delicate appearance, and a long service life.

【Practical Accessories】 The copper pipe expander uses thermal friction to create a revolutionary piping system. There is no longer a contact area between the torch and the valve.

【Easy Installation】 The pipe expander with a handle is small in volume, lightweight, and easy to carry. It's perfect for replacing old or faulty pipes. For air conditioning, simply open the copper pipes and connect the two copper pipes together. This new, high-quality expander is reliable and safe.
