drilling stone and brick |
Masonry is nearly always drilled with a masonry bit and a hammer action drill unless large diameter holes need drilling in which case a core cutter would be used.
Masonry bits come in two different types, the standard fitting and the SDS fitting. The SDS fitting bits come in far more sizes, some of which are over 1metre long. Standard masonry bits are really only suitable for drilling small holes for putting up shelves etc. A standard hammer action drill would not be suitable for drilling a 22mm hole through a 4 feet thick wall, where as a SDS drill should drill such a hole with ease!
When using a hammer drill inside it is essential that you start to drill the hole with the hammer action turned off, or else it makes it extremely difficult to start the hole and can damage the surrounding plaster.

For large diameter holes a core cutter should be used, these again come with both standard and SDS fitting arbors.
