WARNING Be Aware that some sellers add the word Diamond in the title of their listings of carbide coated hole saws. Read listings carefully where the description often makes it clear that they are carbide not diamond coated like these ones. Even diamond coated ones come in various quality grades, This is the top quality DB-HS1 quality, not DN-HS2 or DB- HS3 cheaper ones

This listing is for a Top Quality Drillpro brand FIFTEEN PIECE Diamond coated Drill Bit hole cutter Set 6 mm ~ 50 mm for use with Glass, Marble, Tile Concrete or Granite. This one has 5 more sizes than my cheaper listed 10pcs set and a wider range of large sizes suitable for pipes etc Other sellers list the same single 50 mm hole saw, from the same factory, at a higher price than all 15 from me

Make perfect holes in your glass marble, ceramics tiles or other composites up to 30 mm deep. Drill slowly using plenty of water for coolant while cutting, particularly with the larger sizes.

Outside diameter sizes are 6, 8, 10, 12, 14, 16, 18, 20, 22, 25, 26, 38, 30,40,50 mm See my other listings for many of these sizes and other sizes sold separately
