Drilling Large Holes

Larger holes are often required when installing switches or laying pipes. For this reason, special drill bit shapes and special material are necessary.

If you want to work on wood or soft plastic, you will require not only an impact drill but also special accessories – what are known as hole cutters or holesaws. These enable you to drill in soft materials such as fibre boards or wood.

Accessories made of High Speed Steel (HSS) should be used for working on metal and hard plastics

The Bosch tungsten-carbide multi-purpose drill bit is recommended for drilling in stone or tiles. It is also suitable for hard woods, wooden materials and coated boards.

The harder the material, the higher the frictional forces between the material and the bit. Therefore, water has to be used to cool the holes being drilled in tiles or concrete. Large holes that are drilled in metal are lubricated and cooled with a special drill emulsion, lubricating paste or machine oil.
