How to use these diamond hole cutters:

For the best result invest £35 on a cheap bench drill like the one on the right. They sell them here on e-bay or at screwfix direct. At that price you can bin it when the job is finished! - They really are that cheap.

And if you drill outdoors you can use the garden hosepipe to trickle water over the tile to improve tool life.

Also if the tiles are already fixed to the wall you can still use the cutter but remember to dip it into a glass of water to lubricate. You wont get the same tool life out of the cutter but it will still work.


Normally you would pay £300+ in the shops for a diamond drilling rig. Fine if you want it to last a lifetime! - Not good if you only want a few holes.

Here comes the science bit !

Dont bother trying to use anything like this on the right. You will waste your time, effort and money.

Tiles produced today are much harder than this tool can cope with which is why you need a diamond hole cutter.

Diamond drills are used on glass, stained glass, ceramics, ceramic tile, porcelain, porcelain tile, limestone, marble, granite, slate, stone and fiberglass. Drills used on wood or metal have a sharp metal tip or teeth, that cut into the material. These types of drills do not work on glass, marble, etc. as the tips do not "bite" into the extremely hard material, and cause heat build-up that burn up the bit and cause "heat fractures" in the material. Carbide tipped Spear Point drills are sometimes used on the "softer" types of hard materials - like untempered glass, sandstone and marble and some of the less hard ceramic and porcelain tiles. While they sometimes work, they tend to chip the hard surface very badly, leaving a rough hole and often cause breakage due to fractures from the chipping and heat. Diamond drill bits are designed differently - they have diamond tips that "grind" into the extremely hard materials.

Core drills only drill out a portion of the resulting hole, so they tend to drill much faster than blunt nose drills. Core drills can be used to drill large holes and can be used on most non-ferious hard materials such as glass, stained glass, ceramic, porcelain and fiberglass, ceramic or porcelain tile, limestone, slate, marble, granite and other stone materials. Bonded diamond drill bits have the diamonds bonded to the the edges of the drill bit tip, generally using an electroplate bonding process. These drill bits are generally slow-speed bits and are fairly inexpensive. During use, the diamonds eventually wear off of the bit due to the hardness and abrasiveness of the material being drilled. Bonded diamond drill bits must not be used on metal, concrete, or masonry and require proper speed and adequate water lubrication.

The life of any type of diamond drill bit depends upon the hardness, abrasiveness and thickness of the material being drilled and the specific drilling techniques used (drill speed, pressure and lubrication), however, the diamonds of a drill bit don't actually wear out as much as they wear off due to heat and friction caused by the extreme hardness and abrasiveness of the material drilled. Drilling in glass, ceramic, marble, etc. is a slow process compared to softer materials such as wood or even metal. A fairly deep hole can be drilled in wood in just a few seconds, while it can take 20 or 30 seconds or longer to drill a hole in standard 1/8" thick glass. In some very hard stones and tiles, it may take 2 to 3 minutes to drill only 1/4" deep. Using diamond bits to drill in hard materials is not difficult, however, it takes time. A person should consider that they aren't 'drilling' a hole, as much as 'grinding' a hole.

 

Suitable for both professional and / or DIY use

See below for some real results on the hardest of porcelain surface. Three holes took 10 minutes to cut ! Fantastic...
