This aircraft extension-style bit is made from cobalt steel and finished with a black oxide coating to improve lubricity and help hold coolant near the cutting edge. A 135° split point construction is intended to promote efficient starts, while the right-hand, spiral-fluted design helps lift chips up and away to reduce clogging during drilling.
It’s a versatile pick for jobs involving steel, hard metal, cast iron, aluminum, stainless steel, as well as wood and plastic—ideal for DIY repairs, shop work, and metalworking tasks that demand reach.
