This set of all-purpose bits can drill wood, plastic, or metal and features 135-degree split-point tips to help prevent walking. Get the Bosch drill bits for metal at Amazon, Lowe’s, or Tractor Supply Co.įolks who need to drill a few holes in some metal surfaces but don’t want to break the bank on a set of expensive drill bits may prefer the DeWalt DWA1184 black and gold drill bit set. Smaller bits have rounded shanks that spin as the bit is about to exit the material.Remained sharp and cool during the test, even after drilling several holes in the test material.Drilled holes in heavy-duty steel faster than any of the other bits in the test.Surprisingly sharp for a general-purpose bit that can also drill wood and plastic.Shank type: Smaller bits are round larger no-spin bits.The tips stayed sharp making hole after hole, and they remained cool to the touch during use (while using cutting oil). However, the large bits have no-spin shanks and do a great job of staying in place. We did dislike that the smaller bits have rounded shanks, as they can be a pain, particularly when the bit is about to drill all the way through the material. They drilled holes faster than the other bits in the test, which really surprised us. We were so shocked that these bits were this good that we kept drilling with them to see if it was a fluke. They didn’t walk when starting a hole, and they removed long shavings of metal, proving they remained sharp while drilling. While we’re not huge fans of general-purpose bits typically, especially when it comes to drilling metal, these Bosch bits were excellent. The set includes 21 bits ranging in size from 1/16 inch to ½ inch and is packaged in a plastic storage case. The Bosch bits’ tapered tips can quickly penetrate the metal, balance the bit, and produce a clean, even hole.

Bits also need to be durable and able to withstand the friction and heat produced when drilling through metal. To qualify as one of the best drill bits for metal, the bit needed to perform well in the metal that it’s designed to drill. We tested these Top Picks products to ensure that they had what it takes for drilling metal. The bits that passed these tests were given awards based on their strengths. Afterward, we did our best to hand sharpen each of the larger bits with a file. We did our best to maintain similar speeds and pressure throughout each portion of every test. Then we moved to some heavier-duty 7-gauge flat stock, again testing how each bit made it through the test. We wanted to see how well they’d retain their edge, how hot they’d get, and how long it would take them to bore a hole in the metal. There’s only one good way to test drill bits for metal: We needed to put some holes in some metal! We grabbed some scraps of metal off our welding cart, chucked some bits into our drill, and started drilling.įirst, we drilled into some relatively light-duty 11-gauge steel angle iron, testing a few bits from each pack.
