Hello. I recently purchased an 80mm core bit with 1/2" GAS fitting from you. We will be using this on our bridge saw. What RPM should I use for this tool? What feed rate should I use for this tool? We will be drilling quartzite composites and granite. Is there a chart that has this information for the different drill sizes and for different materials? Thank you for your time and help.

hello Chris,
Do you use the drill bit with an angle grinder?

RPM:
max 6000 (up to 12mm diameter)
max 400 for the bit 14mm-diameter and the bigger ones.
About the feed rate, there isn't a parameter because you go manually, slowly putting pressure on the material.
do not go into the material perpendicularly but use the tool by tilting and swinging while cutting.
As you know quartzite is the most hard material in nature, so be careful and go down slowly.
Use the water to help the diamond tool.
