Bosch Professional GDE 68 dust extraction system (compatible with all drilling tools with max. 68 mm drilling diameter)

Clever, well engineered design. Works perfectly. No regrets purchasing. Using it with Bosch GAS 20L SFC professional vacuum dust extractor. Performs even better than I expected. Secures itself firmly to even fair faced more open textured blockwork. Ideal for when using SDS drill as no mess or dust leakage at all. Just leaves a very light surface dust shadow outline of the unit when taking it off the wall after use which vacuums off easily. Should’ve bought one years ago but had baulked at the price. Having used it in practice and seen how effictive it is, well worth it. No regrets purchasing.

Bought for site drilling and it works extremely well with dust containment. Using with a Bosch portable vac. Very happy

This really is a great companion to the larger Bosch version which is truly exceptional. Together, they can revolutionise how work is done - minimising almost to zero the amount of dust that contaminates where you're working. My only reservation is that there are cheaper brand equivalents available, although I haven't yet had any experience of those. These, though, are brill.

I bought this for drilling in finished homes etc where dust control is essential, I use it with my 18v bosch vaccume with the correct adapator connection etc. So far it has been great, it does catch the debris, leaving very little to escape whilst in use, there is a little dust escapt sometimes, but over all it is good.There are a couple of issues though, first you need to make sure you have it working upright, it it is slightly leaning to the left or right then dust can be sat in it when removed, next run the vaccume for a bit after taking it off or some dust will fall out when you turn the vaccume off.You also oviously need enough space around the drill hole for the extractor to fit, it isnt small! over all not bad, it works, but not perfect.

Great product would purchase again if required.

Found it works really well I tried it with a Bosch GAS 18V-10L and holds it well to the wall. Used it for the first time today drilling a bunch of 20mm holes in fiberglass on board a new catermeran found it collected the dust well. It does leave a foot print from the dust when taken away but easy enough to go over it with the vacume afterwards.

No dust at all connects easily to my nilfisk extractor

It's effective, and extract all dust
