searching for most suitable drill bit for porcelain tiles

[Allenanupam]

I need to drill holes in the tile wall for some household tasks. Therefore, I want to know exactly what type of drill bit will suit best our beautiful porcelain tiles. Because I don’t want to ruin them by using the wrong equipment.

Diamond bits and Carbide bits are the most common ones. Of the two, diamond bits look most favorite for application in porcelain tiles

What about different tips seen on the drill bits?

There are two styles; Core drill bits and blunt nose drill bits

What do you guys prefer between spearheaded and self-feed types? I heard good things about self feed ones

Besides, there are different sizes of drill bits depending on how large i want the holes to be. Which is the most recommended size?

All I am asking these because I don’t want to waste my hard earned money on something and later regret.

Which drill bits will give me most longevity?

Any suggestions I would greatly appreciate, thanks.

Use a diamond bit, go slow and don't push to hard never had any issues

Rotary only on the drill… no hammer.. for obvious reasons!

@Allenanupam what size of holes will you be drilling?

If just for red plugs I use cheap tile bits, and allow 1 per hole (usually get more but some porcelain tiles are worse to drill than others). As others have said go slow and keep the hammer off, cooling the bit in water can help a little. No bits will last very long be they cheap or expensive, be wary of the tip falling off as it will be hot.

Mexco TDXCEL Dry Diamond Tile Drill Bit

Even the hardest materials are no match for these Mexco tile drill bits. They cut through porcelain, ceramic and stone tiles cleanly – all without the need for water, thanks to a wax filling that melts, lubricates and cools while drilling.Designed for use with high-speed corded drills, the bits...

Always this type. They’re the best by far. Most brands seem decent.

A bit of a pain to get started. Screwfix sell a guide with suckers on that makes it easy. Otherwise drill a hole in an off cut of plywood the same size as the drill bit and hold it against the tile till you get started.

Don’t bother with the arrow head cheap bird imo. Rubbish. You’ll struggle to do 1 hole through some porcelain whereas these will do 10+ through the same hard porcelain. A lot more through other softer porcelain tiles.

For good quality, hard porcelain tiles you will need one of those:
New-Ox Dry Diamond Tile Drill Bits-For Porcelain Granite Tile Marble Ceramic-6mm 5060359914354 | eBay - https://www.ebay.co.uk/itm/New-Ox-Dry-Diamond-Tile-Drill-Bits-For-Porcelain-Granite-Tile-Marble-Ceramic-6mm-/274781869899?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=710-127635-2958-0

I would suggest making a guide (piece of wood with appropriate hole in it will do) if you have not used them before or practice first on scrap piece (if drilling without guide you start at 45deg angle). Those are used dry without water but needs to be cooled(dipped in water) once or twice per hole. Switch off hammer action on the drill and set speed to MAX. Don't push too hard and apply gentle circular motion to the drill. You should get 15-25 holes from one.

cheap as chips tile dril 4 or 5mm for small hole. if you want, say, a 1" hole, then stitch drill with the 4/5mm and cbip out.

or.........

The drill is not the issue here, just use a masonry tipped bit without hammers until you have drilled through the tile, then select hammer as normal.
