![]() The drill bit is not fully held in the chuck, like a piston, it slides back and forth. The drilling edges of the drill bit contact the workpiece and are attached through the shaft with the shank that fits into the chuck. The shank is the verge of a drill bit gripped by the drill chuck. The SDS shank is pushed into the spring-loaded chuck without fastening. ![]() The SDS Plus shank is designed with four rails, and the diameter of an SDS Plus shank is primarily 10 millimeters. What Is The Geometry Of The SDS Plus Drill Bit? (Shank Geometry) ![]() ![]() When working on the toughest masonry projects, if you use SDS Plus drill bits, you can get the work done more efficiently and easier. They are not an ideal choice for materials such as wood and metal.įor the ones who engage in massive household projects such as removing walls and breaking up driveways which require a lot of power, it is recommended to go for an SDS drill with SDS Plus bits over a regular drill bit. Consequently, SDS drill bits are used to bore holes in heavy materials such as brick, concrete, steel and stone. These drill bits are amazingly durable masonry drill bits, as the slotted drive system in these drills needs strong drill bits. Mainly, SDS Plus drill bits are best for drilling small-sized holes as they are thinner when compared to SDS Max drill bits. SDS Plus drill bits come in a smaller and thinner shape with two open and two closed grooves affixed by locking balls. SDS Plus bits can drill through the toughest materials, particularly in renovation or demolition, with less risk of bit breaking. Due to the shank geometry, it can use as a quick change drill bit, as well as a hammering mechanism that will transfer to the SDS drill bit efficiently due to the chank geometry. SDS Plus bits are high-power hammering drill bits that are used mainly in demolition and drilling tasks. Among them, 4 cutters cutting head is highly efficient. SDS drill bits have 2 cutters and 4 cutter cutting heads. Hence it can withstand higher compressions and frictions with heating. SDS drill bits tip is made with tungsten carbide. Mainly SDS plus drill bit is used for concrete drilling with rotary hammers. The high-volume, double-helix design of the quad-head bit comes with the patented, high-performance, reinforced core flute to maximize energy transfer.SDS Plus drill bit is a masonry drill bit. 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.Regular and Quad Head ® bit tip configurations are available.įits all current and older SDS-max ® rotohammers from Black & Decker, Bosch, DeWalt, Hitachi, Hilti, Kango, Makita, Metabo and Milwaukee. They are designed to meet precise tolerance requirements and incorporate proprietary features that enhance durability and drilling speed, while improving ease of use. Our carbide-tipped drill bits are premium quality, professional-grade tools manufactured in Germany to the highest industry standards for Simpson Strong-Tie ®.
