How to drill holes in tile using the
"TileBit-Pro"
with the Drilling Kit

1. Fill pressure pump up can about ½ full and pressurize.
2. Layout hole pattern.
3. Connect hoses.
4. Hold guide fixture over hole layout.
5. With "TILEBIT" chucked in the drill, place the bit in the guide fixture notch.
6. Start water flow and start drill.
7. With drill at low RPM and water flowing, apply light pressure to bit.
8. Within seconds bit will pilot into tile surface then increase RPM and bit pressure.

Notes:
Use a small amount of water; a "trickle" is all you need. Because you are only drilling ¼" to ½" deep through the tile, the water is just to cool the bit. If you are going to continue and drill through the underlying cement board or green board, use a little more. Use enough water pressure to assure a continuous flow. 5 to 15 PSI is usually sufficient. To continue the hole through plywood, switch to a conventional twist drill.

The "TILEBIT" is a core drill and does not cut the center core. In small sizes this core may break off inside the bit and not flush out of the bit. If this happens, remove the plastic plug from the back of the bit and push the core out with the supplied rod. Usually 8 to 10 holes can be drilled before you need to remove the cores from the bit.

Keep the "O" rings lubricated with silicone grease. Before storing bit after use, dry bit to prevent rusting.

If the "TILEBIT" should slowdown with use, it can be "sharpened" by removing some of the metal matrix on the face of the bit to expose more diamonds by drilling through an abrasive material, like a cement block or sandstone.

Within limits, the higher the rotational speed the faster the penetration rate. But use judgment, keeping in mind SAFETY, WEAR & TEAR ON EQUIPMENT in selecting the best RPM. Note: a ¼" diameter "Tilebit" works well between 1800 and 3000 RPM and should complete a hole between 10 to 20 seconds.

Experience will help determine the proper pressure and rpm for your best results.
