Twist Drill introduction Twist drill standard products are national standards and equivalent international standards. Once the aspect ratio of the hole being processed is greater than 4:1, it is difficult for a standard twist drill to push the chips out of the cutting zone and out of the hole. The chips quickly block the bit chip slot. At this point, it is necessary to stop drilling, exit the bit from the hole, remove the chips in the chip slot, and then drill down again to continue cutting. This operation must be repeated several times to get the desired hole depth. This drilling method is often referred to as the "peck" method. Using "pecking method to process deep holes will shorten the Tool life, reduce the processing efficiency, affect the quality of the hole being machined.
