Customer Reviews for DeWalt 11mm Extreme 2 HSS Drill Bit
"Drilled 5.5 mm holes in a 6mm thick 304 Stainless steel plate in 2 steps ! Did what took me an hour yesterday(with a lot of cussing), in about 5min today Tip hardly got warm Going to get the full set on next visit . Not the cheapest you can buy but for the time it saves well worth the outlay"
"The drill performs very well even through thick steel plate but you have to be careful of overheating the bit as it did lose it's temper and round off, if this was allowed to happen. Otherwise a very good product if used correctly."
"I needed to drill holes in 3mm thick galvanised steel and ordinary HSS bits were barely scratching the surface. These bits did the job really well, although the tips still blunted after drilling 5 or 6 holes. Expensive, but at least they get the job done!"
