Generic term for all drilling and fixing work in civil engineering, on natural and artificial stone. It is done using drilling tools for installing fixings and anchors.
Tools are equipped with a filter to protect them against wear and malfunctions caused by dust or other impurities. Filter elements can consist of treated paper materials, glass fibre or plastic fleeces, textile or metal fabric.
There is a wide range of fixing types, depending on which building material the fixings are to be inserted into.
Plastic expansion plugs– The classical all-purpose fixing for concrete and solid masonry
Spring toggles– Made of plastic or metal for cavity fixing applications
Cavity wall plugs– For fitting in plasterboard
Wooden dowels– Wooden pins or elliptical pieces of compressed wood (biscuit dowels) for joining wooden parts
A fixing is a joining element used for fitting building components to masonry or wood. Each application has the correct fixing type. It is very easy to use a fixing: drill a hole, insert the fixing into the hole and knock it with a hammer to guarantee a secure fit. Then drive the screw into the appropriate fixing – done.
Accessory with flat, chisel-shaped cutting edge. Depending on the application, there are flat chisels with different widths of cutting edge.
Joining element mainly used in woodworking. The flat head screw has a slanted, fluent transition from the cylinder body to the screw head. This enables it to be “countersunk” in a surface especially well together with the head. It is driven into the wood until the top of the screw head is flush with the surface of the building component to form a smooth surface.
For producing holes with large diameters, e.g. like those required for fitting hinges in furniture
