The Hillman Group 4825 1-Inch Square Bit Number-1, 10-Pack [並行輸入品]

商品説明

Drill Bits are used for drilling screws into wood, masonry, sheet metal and plastic. Bits are held in a tool called a drill, which rotates them and provides torque and axial force to create the hole. Square drive bits tend to last longer than flat and phillips head bits because the bit is less prone to wear down.
