They've got the 3 step drill set for £3.99 starting today, sizes going up to 32mm which is more than enough for 1 inch fittings.

Plus you can make lovely grommet holes for all your electrical doobries and put them in a box, rather than having wires all over the shop like I do.

Got them the last time that Lidl sold them!

Great bit of kit BUT a Warning! They are so good that on thin plastic (and even metal) too much pressure on the drill and they will carve out a bigger hole than what you were looking for!

No problem on a Pillar Drill but easy to do on a hand-held drill. I know 'cos I dun it! Doh!

I have one of these and used it to make 28 mm holes in 5 litre spring water bottle lids when i started out, perfect size for a standard airlock bung.

These are useful for cutting holes for washing machine elements like this:

Because you can drill the holes for the rounded ends then Dremel cut out the straight bit. I might do it even though I've the induction for heating now.

Cutting and a slow cutting speed is key here when cutting stainless. Heat kills cutting tools.
