Review on 💎 Premium Diamond-Coated Ceramic Marble Cutting Tools by Flyshop by Stephen Johnson

No, it doesn't have a pilot nozzle. There must be a reason for this. I read a comment from another manufacturer that the pilot nozzle is not suitable for glass. Anyway I made a template or instructions out of cardboard by folding the box, making a double layer and then drilling a hole in the cardboard with a Flyshop drill bit. Tape the template to the wall. Tilt the chisel at about a 45 degree angle, drill slowly, and then bite the tile wall. If the bit bites into the tile, bring it back to a horizontal position. It stays in place, does not "wander" and the hole is made very neat and tidy. Keep the tile wet to keep the drill bit cool while drilling. This is a well made beat.
