Best Top Hammer Drill Machine - Drill Tech International The Drilltech International is a professional grade corded hammer drill which is available in 240v or 110v. Corded operation has historically provided more speed and power than battery powered designs, and unlike their cordless counterparts corded hammer drills won’t run out of power halfway through a job. They are usually a cheaper option as you don’t have to invest in batteries and chargers; however they are not particularly well suited to driving screws – it is rare to find any kind of torque control on a Top Hammer Drill Machine, and they are often slow to brake once the trigger is released. On top of this they are usually fairly large, heavy machines designed for two-handed operation, all of which makes them difficult to use with precision – especially in cramped spaces. Like corded rotary drills, hammer drills are often available in 110v or 240v – the 240v options can be used with standard household power sockets but the 110v versions can only be used with step down transformers as used on building sites and in other industrial environments.
