【Ordering Instructions】The price is per piece.,everyOrders for this product must be placed in multiples of 10 (starting from 5 pieces at 9.0mm or above), and orders with fewer than this quantity will not have packaging boxes. Any shortage of goods due to this reason will not be responsible for.

【Operating Instructions】If you need to drill metal, please use the bench drill as much as possible. Because the hand drill drills metal, due to the existence of manual operation, it is easy to break the drill bit, and the power of the hand drill is generally small, which makes it relatively difficult to drill metal. This is not a quality problem. Drilling metal on the bench drill is very easy, and if there are problems such as easy breakage or not being able to be drilled within the scope of application, a refund or exchange is available.
