If it's semi cut already. Tap it out from the top with a nail punch. Frightening experience! Don't be shy with it.
 
I've done one, it was squeaky bum time lol, came out fine in the end. I just pay the extra now and have them do it. cust pays in the end anyway.

Customer is supplying it so didn't know until the kitchen fitter phoned me today.
 
Get the customer to sign a letter, stating its their responsibility if it breaks. Otherwise, let someone else do it.
On a brighter note, I've done a few now and never had a problem.
 
Just drill the stupid thing out with a diamond drill, I'm not taking a hammer and chisel to a £200 + sink. Manufacturers think they are saving us time but will they buy me a new sink if it cracks?

I hate getting people to sign stuff, its like saying I don't trust you. Never had to ask yet.
 
They tap out easily with a nail pinch. Sinks are made of fireclay not porcelain so they are not fragile. If it is an inset sink sit it in position to support it.
 
I did a Franke sink and hit it as hard as i dare with a centre punch and then I hit it again harder and it didn't budge or even sound right so I drilled it.
 
~Haha i put a thread on here about this couple year ago ,cust said all i need to do is whack with hammer .
I did and sink shattered lol
 
Did a rangemaster one on Saturday. Had to hit it harder than I thought I would.
 
get customer pair of goggles and gloves and tell them to follow instructions, its your sink!!
 
I think it was Tams who quoted on another thread

" everything can be repaired "

he should also include

" or replaced "

I'd like to see him hit it that hard if he was self employed. Its okay if its someone elses money.
 
Ensure colour sticker is in the centre of the pre-formed tap-hole.

Follow the descriptive line drawings shown on template or:

Take the sink out of the box and rest the sink vertically against your legs with the face of the sink facing outwards, ensuring that the tap-hole is for the correct hand-drainer. Take care not to damage the edge of the sink in the process.
Take a centre-punch and place on the centre of the colour sticker.
Strike the punch hard with a hammer. This will result in the core of the tap-hole being knocked out. Finish off, using the ball of the hammer and a round file.
 
Ive always used a ball pein hammer never had a problem sometimes they do need quite a hard whack:whatchutalkingabout
 
See ! We told you so!?
Probably s4it yourself, but it was ok ?
