Drywall bit holder

[WillB77]

I bought a drywall bit with a depth stop. I also bought the bit holder to go with it -

The bit won't go into the holder and didn't come with any insrtuctions. There's a rubber washer inside the bit holder that seems to stop the bit engaging with the hex bit inside the holder, but even if it did it would appear to only go in a couple of mm.

I know that's not particularly clear but why is a drywall bit holder different from a regular bit holder?

The drywall bit will fit directly into a drill, but wondered what the bit holder was supposed to do?

Many thanks for any advice

What happens if you try sliding the knurled cyan sleeve towards your drill, will the bit engage properly then?

use the drywall bit on its own in your drill,they work pretty good

to use the drywall bit adapter you need a ordinary 25mm phillips #2 bit ,then turn the larger blue bit to show more or less of the bits tip and the smaller blue ring to lock its position ,this acts as a depth stop,the end of the adapter is magnetic so screws are held onto the bit

Yup, the knurled collar is a depth stop, to prevent the screw head tearing through the paper. Screw or unscrew to put it in deeper or shallower.
