A Morse taper shank (MT shank) drill is a type of drill bit that features a tapering shank that is designed to fit into a drill chuck or the spindle of a drilling machine. The shank is typically made of hardened steel and has a self-holding feature that allows it to be inserted into a matching tapered hole without the need for a locking screw. Morse taper shank drills offer several advantages over other types of drill bits, including improved accuracy, reliability, and ease of use. The taper ensures a tight fit with minimal wobbling or slipping while drilling. MT shank drills are commonly used in metalworking, woodworking, and drilling applications that require high precision and durability. They are available in a wide range of sizes and styles to fit different types of drill chucks or spindle sizes.
