Coated with a black oxide finish for reduced friction and minimal heat buildup, these heavy-duty drill bits are rated for use on metal to produce clean, burr-free holes. The black oxide drill bits in this 21-piece set from Ryobi have a 135-degree split point so they start penetrating on impact and don’t wander on your workpiece. Also suitable for wood and plastic drilling, these durable bits are constructed with a high-speed steel core to meet the demands of repeated use.
