How to drill tiles with the Dexter hole saw ?

DEXTER diamond hole saws are ideal for drilling in floor tiles (porcelain stoneware, granite and marble). They feature a centering drill for precise positioning of your hole saw. The included sponge allows for water cooling, which extends the life of your drill bit and prevents the release of dust during drilling. They are available in several diameters.
It is important to use a water spray to continuously spray your hole saw during drilling, and a rotation speed of 2600 rpm.
It is important not to use the percussion function of your machine/drill to avoid damaging both the hole saw and the material to be drilled.
