Sds max bits11/13/2023 Bosch calls their the Speed Clean Bit, but many other drill bit companies have come to market with cheaper options that are compatible with most HEPA vac systems including these options from DrilTec. These bits attach directly to a vacuum so all dust is sucked up the core of the bit, allowing for faster and cleaner drilling. Many were able to develop a hollow bit that’s compatible with both SDS Max and SDS Plus drills. When OSHA released their changes in silica dust standards, power tool manufacturers were quick to adapt. The major difference is that chipping bits and drilling bits that are used for spline drive drills have different shanks as one is smooth and the other has splines. They are very similar in capacity and variety to the range available to SDS Max bits. Spline bits have become much less common than SDS Plus or SDS Max. You will often see bits as long as 36” or some may even have an extension that allows you to cut well over 4.’ These do allow for a much longer length as well. Of course, there are plenty of bits smaller than 1” that can be run with an SDS Max drill, but it can often be overkill. Industry standard says that any hole over 1” is cut with an SDS Max bit. If you’re whipping out the big guns to cut bigger holes in masonry or concrete, you’d better have a few SDS Max bits in your toolbox. They can often be found over 1,” but most contractors move to a drill with more power when drilling holes larger than that. Most commonly, SDS Plus bits are used for holes drilled in masonry and concrete (carbide bits) up to 1” in diameter. As seen above, it is a pattern that is consistent with all SDS Plus drill receivers. There are multiple types and sizes of bits with an SDS Plus shank. Please note, SDS Plus bits and drills only pertain to the shank. At the time, it was a major advancement in the clamping of drill bits, thus allowing holes to be drilled more efficiently. The SDS system is said to have been developed by Hilti and Bosch in Germany in the 1970s. This does NOT mean the size of the shank changes, just that the drill has more or less power for cutting holes or chipping concrete. When you’re looking for a drill, whether it’s SDS Max or SDS Plus, you’ll notice a rating such as 1” or 1 1/8.” This refers to the size of bit the drill is capable of running without losing power. The question is, which one is right for you for the job at hand. SDS Max, SDS Plus, Spline, and straight shank bits can be found in almost any hardware store in the world. There are four main categories in the marketplace, and they all serve a purpose. The high-volume, double-helix design of the quad-head bit comes with the patented, high-performance, reinforced core flute to maximize energy transfer.How did buying a drill bit get so confusing? Is there a right and wrong? Is there a better or worse? Are all of these ‘improvements’ really even improvements? 4 x 90° head geometry crushes through rebar and prevents sticking in reinforced concreteĪll the features of single cutter bits and the quad-head dual-cutter are designed to improve durability and drilling speed.Patented, high-volume, multi-flute spiral quickly channels concrete dust from the hole to improve drilling speed.Chisel-shaped drill-bit head penetrates the material and directs concrete dust into the multi-flute spiral.Drill bits conform to ANSI Standard B212.15.Heat-treatment procedures and shot-peened finish increase surface hardness, drilling speed, reduces drill bit wear and improves resistance to bending forces.Chromium-nickel-molybdenum steel alloy body ensures hammering quality and extended service life.Most bits contain a centering tip that facilitates easy spot drilling.Uniformly brazed carbide inserts result in longer bit life.
