The external point angle design of this cobalt twist drill bit allows for fast and efficient drilling, with effective chip removal to prevent clogging. This results in clean, precise holes with minimal burrs or rough edges, great for a range of materials including stainless steel, steel, sheet metal, cast iron, titanium, and other alloys, as well as plastic, aluminum alloy, wood and other softer metals, is well-suited for both DIY and professional use. Notice: Please keep cool and gentle using, the working life of the twist drill bits can be largely prolonged by proper usage. When using a hand-held electric drill, pay attention to speed adjustment.
