20.5mm x 1100mm Morris Extra Long HSS Twist Drill

Morris extra long HSS twist drills give you reach that a standard drill bit cannot. This product covers 10mm to 30mm drills in 1000mm and 1100mm overall lengths. The ET series is most popular with tradesmen and other engineering professionals, and them as general purpose drills for machine and hand held drilling. They suit low and high carbon steels, aluminium and other non-ferrous metals, soft woods, hardwoods, plywoods, chipboards, plastics, composites and plasterboards. They are also suitable for most battery drills.

HSS means high speed steel. Flute length is the length of the spiral cutting section. Sizes from 10mm to 13mm have a 118° split point and a bright finish, which means no surface treatment and an as-ground surface. The split point centres itself and needs less end thrust. Sizes from 13.5mm up have a 118° notched point with a 30° helix and a black steam tempered finish. The notched point starts faster and wanders less. Sizes from 14mm up have 3 milled flats on the chuck end for a non-slip grip in a three jaw chuck. These are the longest of the three length groups, for the deepest holes. Choose your diameter and length from the options above. For less reach, see the 300mm and 500mm drills and the 700mm and 800mm drills, which are sold separately.
