The KIK^® HS Brad Point Bit has a unique tip design allowing it to bore wood, plastics and sheet metals exceptionally fast, clean and easy. The tip contains 20% more cutting surface. To accommodate the speed with which this bit drills, the flutes have an additional extraction ridge to clear the bore continuously and efficiently. The tip design permits plastics, laminates and even acrylic sheet to be drilled without melting, clogging or melting. Sheet metals are drilled with no burr left behind. KIK HS Brad Point Bit are available in standard jobber lengths and 8-1/4 extended length. The extended lengths have a hole near the tip for pulling wires through the hole with the bit that made the hole!
