1. The straight shaft

2. The curved shaft

Before buying them, just ensure that a straight shaft is sturdier and reliable. They can reach many areas, have better torque, and can serve for many other purposes too. Whereas the curved ones are light in weight, may vibrate, and perform with a lesser output. The modern-day shafts are straight and are preferred more.


Most of the manufacturers come with warranties that are not known or used by the customers. Due to some mal-functioning, we even try to abuse the company as a customer. But this should not prevail, as most of the products offer good services after they sell their products. Any kind of faults or defects is also taken care of by the company.
