For drilling into many different materials
A truly useful multi-purpose drill bit, designed for drilling into all materials including wood, masonry, ceramics, UPVC and even steel. This is achieved by diamond grinding the tungsten carbide tip to produce a multi-material ability. As with all cutting tools, it is essential to clear the waste material quickly and Bosch have achieved this by providing a steep aggressive flute. For strength and to withstand both rotary and all purpose drilling, the tungsten carbide tip is set and brazed into the drill head to precise criteria. All contained in a ROBUSTLine case: 5 x 85mm 5.5 x 85mm, 6 x 100mm, 6 x 100, 7 x 100mm and 8 x 120mm, 10 x 120mm.

Almost perfect!I've mainly used these on masonry but found they'll drill through pretty much anything as they're supposed to. I only have one gripe with them and that's that they don't seem to clear the dust out the flutes very well?
