As soon as you begin to cut into the glazed pottery return your drill to its normal vertical position and continue to drill through, slow to begin with and with little pressure, too much and you may break the pottery. The angling of the drill will again help to prevent any skittering across the surface. Step 3 Start the drill on the lowest rpm and angle your drill on the masking tape to begin the drilling whilst at the same time squeezing water from your sponge directly onto the drilling process. I got the Dremel 4000, high performance, I figure that since drilling stone is heavy duty work, it’s a good idea to have a heavy duty tool) Hollow, diamond-tipped coring bits (I use the 2.5mm bit) These are much faster and effective for drilling holes in pebbles than a solid drill bit.

The masking tape helps to prevent any skittering across the surface which when you begin to drill and make the first initial cut this can happen. Step 1 Mark the position of where you require the hole to be with a marker pen and place a strip of masking tape over the top.
