The construction of a 20-inch drill bit typically involves high-quality materials such as high-speed steel (HSS) or carbide-tipped, ensuring durability and resistance against wear and tear. HSS bits are suitable for softer materials, while carbide-tipped bits are more robust and can handle harder substances. The cutting edges are designed to maintain sharpness, allowing for efficient and clean drilling.
When installed in manholes or potential pedestrian traffic areas, flow monitoring flumes can be a hazard. A typical flume installation is an open trough that that an operator can inadvertently step or fall into.
