Masonry bits are obviously the place to start when looking for something capable of drilling concrete. This is important because concrete creates a heck of a lot of dust. You will definitely want a bit with a slightly wider tip than the shaft, and ideally the tip will be coated in tungsten carbide for durability.įour-flute designs can also be helpful, as they pull dust out of the hole more efficiently. Most commonly, they have a wider tip, allowing for easier penetration of super-hard surfaces. Masonry drill bits come in a few different shapes and sizes. It’s not compatible with SDS or SDS+ drill bits. There is also “SDS heavy”, which is a completely separate type of drill bit used for heavy masonry work. SDS+ is an improvement on the original SDS design, and it’s what most modern drills use. Note that these days, most bits are sold as “SDS+” instead of just SDS.

It’s one of the toughest types of carbide, used for armor-piercing shells, and is twice as strong as steel. Tungsten carbide is a type of carbide, where tungsten as used as the metal in the compound. What’s the difference between carbide, rock carbide, and tungsten carbide?Ĭarbide is a name for a compound created of metal and carbon. This doesn’t mean that you should avoid these no-name drill bit tips completely, as some of them are actually quite good.Įven some of the big-name brands have started outsourcing their work to low-quality factories in China, meaning that they’re not necessarily going to make a tougher drill bit than a no-name brand. Some no-name companies fail to use the right carbide compound, or apply it improperly, resulting in a drill bit that becomes blunt very quickly. The toughest masonry drill bits come with a carbide tip.Īnother consideration is the brand.
