Frequently Asked Questions
Q: How does a Rotary Hammer drill work?
A: A small piston operated by the electric motor pushes compressed air against a
metal spring loaded plate which in turn heavily impacts with the drive shaft
connected to the chuck. Each single impact of energy delivered is measured in
“Joules”
NB: A joule is the work done or energy required to exert a force of one newton for a distance of 1mtr.
Q: What is SDS all about?
A: An acronym for “Stick Rotate Seat” , though there are many other versions and it’s
difficult to know which is correct. It was system developed by Bosch which there are
several forms available such as SDS, SDS PLUS and SDS MAX. Basically the difference is
their increased duty rating and size of the associated bits. Because of this special
fitment, a “Chuck Adaptor” must be fitted to be able to use standard round shank drill
bits.
