The SDS hammer drill performs better than conventional hammer drills when drilling through concrete, bricks and hard masonry, as it can drill through these substances up to 90% quicker than normal hammer drills. If these are the sort of tasks that you are performing on a regular basis, then the use of an SDS hammer drill will enable you to complete your workload much quicker.
Due to the fact that an SDS hammer drill can move through hard masonry in seconds, it is essential to take care when drilling through walls, so as not to remove a large chunk of wall when the drill hammers its way out.
Safety is improved by the safety clutches, which cut the power to the drill bit if jams. This feature is important as without it, if the bit were to jam, you could lose your grip of the drill and injure yourself.
Tips when buying an SDS drill
Check the weight - If the drill is used regularly the ideal weight would be 2kg, as a 4kg one used regularly would be too heavy after a while and affect work rate. Lower cost drills do tend to be on the heavier side.
Check the speed – Decent speed control will allow you to be more careful entering and exiting substances.
Check the lock settings – Adjustments can be made that enable you to lock the rotation of the drill, so that it won’t rotate when trying to chisel into substances. This is particularly important when using the drill in hammer mode to chisel accurately.
