110mm Core drill recommendations

[365drills]

We do the 110mm diamond core drill or holesaws for drilling holes into:

Tiles - Granite - Porcelain - Glass - Ceramics - Travertine - Pottery - Marble

It will drill holes down to the depth of a stanard 30mm thick granite kitchen worktop.

To stop the diamond drill from slipping just cut out a bit of plasterboard.

Stand on it.

Once you push through the plasterboard then start drilling holes into your tiles.

i also dont do that many cores and used to hire every time. On the last job i bought a sparky BUR2 350E (£120) from machine mart or screwfix and a cheap core set from the electrical wholesaler TCL (£50).

while on the subject how much faster and how much longer to expensive cores last than cheep ones (i now only but good qual drill bits since they are much faster and last much longer)?

sds drills dont go fast enough to do a decent job and you tend to burn them out quickly. the marcrist is a good drill and worth the money you have to pay. Ibought a sparky recently which was supposed to be a core drill but it has already burnt out one clutch. Back to marcrist again once it gives up.

I do find that the clutch sliops quite easlily on the sparky, easy on the arms but hard on the clutch so I can well understand that.

You need a large clutch breaker type drill. A 110mm core will knacker a regular SDS drill and burn out the clutch.

The Marcrist ones are pretty good as are the Norton ones. Avoid "market stall" ones.
