How to drill holes with the
|
||||
| Whether you have one hole or
hundreds, drilling large diameter holes in the hardest tile is a simple
straightforward process with the "TileBit" Diamond Hole Saw that will give you
a clean, accurate hole at a reasonable cost. The "TileBit" Diamond Hole Saw is a professional wet cutting diamond bit. Water is applied to the bit during the drilling process to both cool the bit and to remove the cuttings generated while drilling. The water can be applied ether to the outside of the hole saw or from the inside using the Arbor Coolant-Swivel. This 'How-To' will cover both showing the advantages and disadvantages of each. |
||||
The "JR" system, (where water is applied to the outside of the bit), has a lower initial cost but is less efficient than the "Pro" system and is recommend if you have only one or just a few holes. Care must be taken to ensure proper lubrication and a "helper" is often very useful to apply the water as you drill so you can keep both hands on the drill.

If using hand held drills, it is strongly recommended a ¼-inch pilot hole be drilled on center of the larger hole, this pilot hole will be used to guide the diamond hole saw and help prevent walking and jamming. The pilot hole can be drilled with a "TileBit-Jr", "TileBit-Pro" or a ¼-inch Diamond Pilot Bit in the Arbor Coolant-Swivel Note: If drilling using a drill press with a good clamping system for the tile, the pilot hole may not be necessary. |
|
||
After drilling the pilot hole, complete the hole through the backer board using a standard twist drill or carbide bit. |

|
With the "TileBit-Pro" system the Arbor Coolant-Swivel comes with a Pilot Guide that rides in the pilot hole and sprays water to the inside of the hole saw. With the "TileBit-Jr" system you will need to ensure your getting water to the inside by spraying through the holes of the hole saw or by slightly lifting the hole saw out of the hole and spraying through the gap. In ether case you do not need to flood the place. A "trickle" flow is sufficient but do not run the bit dry. |

Notes: it is recommended that a conventional hole saw be used to drill the backer board and any wood you may encounter. |
