Get masonry drilling right, though, and a tough job becomes a lot more predictable, with the desired results: a round hole made to the proper depth without breaking the bit or burning out the power tool. The shops’s floor is concrete, and the walls concrete block. It might not be often that you actually need to do this, but the task crops up every once in a while, as we’re experiencing now that the shop floor is done in the new Popular Mechanics office and we set about building and installing all the equipment we need. He even rewired their bass boat for fun one weekend as a young teenager.To make a hole in masonry and rock, you need a masonry bit-and to know how to use it in the correct way. From his dad, he was able to learn irrigation, landscaping, car maintenance, basic electrical, and more. In fact, Kenny still uses several pieces that his grandfather made more than 30 years ago.Īt home, Kenny’s dad made the family budget stretch further by doing many DIY repairs around the house. Building everything from bookshelves to lazy Susans, he became extremely accomplished while his young grandson observed, fascinated at the way raw wood could turn into something both beautiful and functional. His grandfather was an airplane mechanic in WW2 and took up woodworking as a hobby after retiring from the power industry. Kenny’s life around power tools started early. While that might not sound like a direct line into the power tool industry, his analytical and scientific mindset help him design repeatable testing methods for Pro Tool Reviews’ head-to-head testing and offer highly objective comparisons in his reviews. This isn’t a concern if you’re using a Hole Hawg. The extra cutting edge on Diablo’s SPEEDemons means you need a bit of a boost to make that last push through. It’s a common characteristic in many of the hole-making accessories we use. If you’re using a drill that’s right on the edge of the power you need, there’s a good chance it will stall at tear-out. ![]() Diablo’s efficiency cushions the lead a bit while clearly cutting holes faster. With most modern brushless right angle drills and higher-capacity batteries, you already have enough work time to give your second battery more than enough time to charge. Here’s the other thing-you’re not going to use a 1.5Ah or 2.0Ah battery when you’re doing this kind of work. We didn’t see that high of an efficiency gain using the higher-quality bits we tested with, but we can see how it’s possible against lower-quality ones. Diablo claims than you get up to twice the holes per charge. It’s not a 1:1 trade-off between speed and effort that results in the same number of holes per charge, though. That was particularly obvious with our 2 9/16-inch testing as Metabo HPT’s brushless motor produced more heat when using the Diablo bit. With both standard and right angle drills, it was clear the motor had to provide more power to keep the bit moving. That said, we were able to use our standard drills with bit sizes under 2 inches easily and in some cases, at high speed. Most plumbers and electricians have a Hole Hawg-style right angle drill and that’s really the best tool to use on rough-in applications. We’re not really offended by that, though. ![]() Some of the flagship pistol-grip drills we tried didn’t have enough muscle to keep that 2 9/16-inch bit moving. Not all 18V/20V Max drills can handle drilling the bits over 2 inches. While Diablo SPEEDemon self-feed bits are clearly faster, there are a few things to consider as you go up in size. Using the same 2 9/16-inch bits, Diablo opened up a much larger gap of 5 – 6 seconds compared to the others. Low speed was where things got interesting. High-speed drilling with the 2 9/16-inch bits gave us about the same gap as the handheld, but with faster times and much smoother boring. Using the Super Hawg netted different gaps than we saw from our hammer drill.
