put some tape (electrical/masking) on the surface before drilling

Probably crap but you never know. Worth a go...

had a few cheap packs and they are fine as and will cut multiple holes, helps to keep the sleep slow and plenty of water (i use a trigger spray bottle) and also let the bit do the cutting and don't apply too much force

As braddock says, masking tape has always worked for me.

I have tries to see the picture but do not understand how this item could help for DIY. Any explanation or link on how to use it ??

Showing price in US dollars. What do i have to do?

Thanks - never thought of that - I am not a craftsman

Thanks, just ordered.

Thanks for the tips. I got some drills from China to drill holes in the bottom of a ceramic flower pot. Think the drills are OK, but I could not get started as they kept skating around on a very shiny surface.

Dont forget tcb 6.3% https://www.topcashback.co.uk/banggood/

Trick is with these things to keep them cool. Get a small sponge with water on and put it against the drill bit. If your drilling on a vertical surface then put it under to catch the dust too.
Also go in at an angle on low speed to start to build up a groove otherwise they can skate around. Or if you've got a thin piece of wood and a similar size normal hole saw drill through that and use as template.
I've been building my ensuite recently and picked up the tips online

I have two holes to cut and this would be ideal . Unfortunately I need this by Monday otherwise I'd be taking a punt

Can't see them being good quality but if you only have a few holes to cut worth a try. :smiley:

This is the type of thing you will never need (like the 5 otg cables i bought the other day)

Till you need it.....

I wouldn't bother these will be rubbish and not worth the small amount of cash they cost

can imagine these are half a hole per drill bit on porcelain but worth a go for the money.

Does that include delivery? Or I store?
