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 3 mm ~ 42 mm for use with Glass, Marble, Tile Concrete or Granite. This one has 5 more sizes than my cheaper listed 10pcs set including handy small sizes down to 3mm & the largest 42 mm ones suitable for pipes too big for the common sets Other sellers list the same single 42mm hole saw, from the same factory, 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 3mm 4mm 5mm 6mm 8mm 10mm 12mm 14mm 16mm 18mm 20mm 22mm 25mm 26mm 42mm See my other listings for these sizes & 35mm size sold separately
