Hammer drilling in concrete
How well combination drills, with hammer action, drill through concrete. We aim to drill 50mm holes and we record how quickly the drills can do this.
Rotary drilling in stone
How well the drills sink holes in sandstone. We use 6mm bits and aim to reach 30mm.
Rotary drilling in wood
How well the drills sink holes in beech. We use a 6mm drill bit and aim to reach a depth of 40mm.
Rotary drilling in metal
How well the drills drive holes in steel. We use a 6mm bit and aim for a depth of 6mm.
Screwdriving in metal
How well the drills drive screws into steel.
Screwdriving in wood
How well the drills drive screws into pine.
This is based on the number of holes and screws that a drill can sink and drive on a full and a quick-charge. It also takes into account the difference between the actual and the stated discharge times as well as the amount of energy discharged from the battery after not being used for a month.
How durable the motor for each drill is - we run drills through over 2000 cycles of drilling, resting and screwdriving.
Ease of use
How easy the drills and the chargers are to use.
