TE-56

The TE-56 Hammer Drill was made in 2010 with the intention of being used professionally in a construction setting. It is designed to drill into concrete/masonry and for light-medium duty chiseling. It is a rotary hammer with Active Torque Control (ATC), which is used for additional safety precautions since it will cause the drill to stop if it jams or gets stuck. It also includes Electronic Overload Protection, which breaks the circuit if an overload is detected in order to avoid damage to the drill. Replacing the TE-56 Hammer Drill could cost upwards of $1,000; therefore, using the Hilti Hammer Drill TE-56 repair page, buying parts, and fixing the hammer drill yourself is very beneficial.

The drill includes several other features like chucks, switches for speed control, grips, lubrication, and indicator lamps for power levels. The most common issues from this drill model include electrical, plug, and cord issues. The plug issues were related to the polarized plug used since it was a double-insulated tool and did not always properly fit outlets.

The rotary power tool, model TE-56, has been discontinued, and newer designs in the Hilti hammer drills have been developed to replace the older drill. The latest version, Hilti Hammer Drill TE-70 AVR, is wireless, easier to use, and produces more power used for more dense materials.

Inside the rear handle is the black control switch. The drill has a black nozzle where the drill bits are inserted and a black power cord located on the bottom of the rear handle. The hammer drill comes with a black cylinder-like support handle near the front. The function selection switch is black and located near the top middle of the drill. On the top of the drill is a black removable depth gauge. Also located on top of the hammer drill, but near the rear, is a black control switch power button. The activator indicator button, outlined in red, is at the bottom left of the rear handle, along with the indicator for reduced power and the switch for reduced power, in black. Inside the rear handle is a service indicator. At the bottom of the drill "body" are four ventilation holes.
