Best Review

Customers find the drill bits to be a good value for the price. They are made of good material and hold up well over time. The bits work well on wood, plastics, and soft metals like aluminum and copper. However, some customers report that the bits chatter when used in a drill press.AI-generated from the text of customer reviews
