Bosch ProfessionalGDE 162 dust Extraction System (Compatible with All Drilling Tools with max. 162 mm Drilling Diameter)

When connected to the hoover,it stuck to the wall,brush type bristles prevented dust contamination when drilling hole in kitchen cavity wall.Would recommend .

I bought this after much consideration as to whether it would pay for itself over time as they are quite expensive for what they are.And was very happy with it. I used a Henry vacuum with a clean filter and new bag and it stuck to the wall very well indeed both the outside rough brick and the smooth plastered wall inside. I had a kitchen extractor fan to install so the dust would have been a nightmare if i hadn’t used this. I removed the brush and it managed a 152mm core bit with ease. Also, i didn’t need any other hose attachment either as the Henry hose end fitted fine.Yes its a tad pricey but works a treat

Finally a solution to dust extraction when dimond coring 100mm for bathroom or kitchen extractors.

Used with Henry vacuum cleaner, as others have stated it does leave a dust footprint on the wall but this wipes off easily and at least the floor stays clean.

Absolute game changer

Having used the Bosch dust extractor fitting inside a loft to a cut a core in a gable end I found it invaluable. When connected to a suitable dust extractor there is no dust apart from a small amount when removing the extractor fitting from the wall. It sticks like a limpet even on uneven block work.

This is prob one of the best ppe products ive ever bought , no more dust while coring holes, the suction power is brilliant not had it fall off once. Highly recommend

150 mm hole in wall and very little dust anywhere. The good lady was very happy. A woman happy is praise indeed
