Morris 17.5mm x 1200mm Extra Long HSS Twist Drill

Morris extra long twist drills are 1200mm long, so you can drill a long way in one pass. They are general purpose HSS drills for hand held and machine drilling, popular with tradesmen and engineering professionals. HSS is high speed steel, the usual steel for metal drills. They cut low and high carbon steel, non-ferrous metals, aluminium, soft woods, hardwoods, plywood, chipboard, plastics, composites and plasterboard. There are 34 sizes from 10mm to 30mm, and each product is one drill.

The shank grows with the drill: 10mm on the 10 to 11.5mm sizes, 12mm on the 12 to 20mm sizes and 16mm on the 20.5 to 30mm sizes. Every shank has 3 flats for a non-slip grip, so check that your chuck opens wide enough. Points differ by size. The 10 to 13mm drills have a 118° split point with a bright, as-ground finish, which is self centering and suits general work and non-ferrous metals. The 13.5 to 26mm drills have a 118° notched point and 30° helix with a black steam-tempered finish, which starts faster and wanders less.
