How to use?

Step 1: Clean the surface and mark down the position of the drill hole, angle drill 45 degrees to start the hole slowly.

Step 2: Keep wet with water.

Step 3: Being drilling at low speeds. Angle drill to vertical position once the hole has appeared.

Step 4: Slow speed down to drill the hole off and for the exit hole to prevent a breakthrough.

Note: If you smell burning, back off! Either your speed is too high or the pressure you’re applying is too much. You’re drill bit should never be hot to the touch, not even warm. – Slowest speed – Coolant – Minimum pressure

The general rule is the smaller the diameter of your drill bit, the faster drill speed you can use. The harder your material, the slower drill speed you should use.
