Ever wondered why your hammer drill just bounces off when you try to drill holes in a wall, when other drills seem to go straight in?
The reason is in the mechanism. Most drills with a three-jaw chuck use a vibratory system to get the hammer action, known as a percussion drill.
Professional drills have the Bosch SDS system which uses the principle of a reciprocating piston which strikes the end of the drill bit. This impacting system gives a much more powerful and effective action. The SDS drill bits are specially shaped to prevent them slipping in the chuck adding to the power.
Of course these professional drills are much more expensive to buy so why not make short work of your masonry drilling by hiring from Jackson & Gocher Hire Centre. Their friendly and helpful staff will be pleased to advice on the best tools to use to tackle your job.
