Rotec SDS+ Quattro-X hammer drill Ø 6.5 x 100/165

On this page you will find the drill bit with article number 202.0651, listed under tool accessories. Below you can read what to consider when choosing and using an SDS+ drill bit.

What does the size 6,5x100/165 mean?

The first dimension, 6.5 mm, is the diameter of the drilled hole. The second dimension, 100 mm, is the working length: the maximum depth you can drill. The 165 mm is the total length of the drill, including the part that sits in the machine's drill holder. Choose the diameter based on the plug or anchor you will use, and the length based on the desired hole depth plus the space needed for drill dust at the bottom of the hole.

Which machines is an SDS+ hammer drill suitable for?

SDS+ is a fastening system in which the drill is slid into the holder of a hammer drill or combi hammer and clicks into place. The drill can therefore make a back-and-forth hammering motion, which is needed to work concrete and stone effectively. Before you start, check whether your machine has an SDS+ chuck, because an SDS+ drill does not fit in an ordinary drill chuck.

Tips for drilling in concrete and masonry

Use the hammer function of your machine and let the drill bit do the work: too much pressure causes more wear than speed. Pull the drill bit back a little regularly while drilling so that the drill dust is removed from the hole. Wear a dust mask and safety goggles, and blow or vacuum the hole clean before inserting the plug. Check the drill bit for wear after use, as a worn drill head drills more slowly and less accurately.
