The term rod drilling machine typically refers to a type of drilling equipment that utilizes a rotating drill bit to create cylindrical holes in a workpiece. The 'rod' in this context often refers to the steel tubing used in oil and gas drilling, where the machine is employed to drill boreholes deep into the earth's surface. The machine's design allows for the drilling of deep, accurate, and consistent holes, which is critical in these industries.

FRP ducts, primarily composed of glass fibers embedded in a polymer resin matrix, provide exceptional mechanical properties. The glass fibers lend tensile strength while the resin provides rigidity, making these ducts highly resistant to impact, wear, and tear. This resilience makes them ideal for use in harsh environments where exposure to chemicals, extreme temperatures, or corrosive substances is common.

Small drill bits, often ranging from fractions of an inch to around ¼ inch in diameter, come in a variety of materials and shapes to cater to different tasks. There are high-speed steel (HSS) bits for general-purpose drilling, cobalt bits for drilling through harder materials like stainless steel, and titanium-coated bits that offer increased durability and heat resistance. Each type is a specialized tool, much like a chosen word that perfectly fits the context of a sentence.
