What Materials Can I Use Diamond Drill Bits On?

Diamond drill bits are perfect for drilling holes through hard materials such as these:

• Glass, sea glass, beach glass, fused glass
• Stone, gemstones, rock, pebbles
• Ceramic, porcelain, tiles, glazed pottery, plates
• Shell, antler, bone, fossil
• Very hard wood

Diamond Drill Bits - Why should I Choose?

• Small Diamond Drill Bits have a solid end and therefore a larger surface area so they last longer than the small diamond core drills, but may take longer to drill a hole. They are more robust and therefore ideal for very tough, dense pieces of sea glass, very hard stone, precious stone, gemstones, hard shell, bone and antler.

 

• If you're a regular user of diamond drill bits it is worth having a combination of both small diamond drill bits in your tool box as sometimes you don't know if you have a very tough material until you start drilling!

Operation Note

• As with all diamond drill bits you should use water as a lubricant and coolant.
• Being hollow, allows the water to flow up inside and around the inner core of these drill bits as you are drilling, helping to keep the drill bit cool and removing the debris.
• Start your hole diagonally, make a round trace and then hold drill straight.

User questions & answers

Question:	Does it work with quartz countertop
Answer:	According to the Mohs Hardness scale, Glass is a hardness of 4, Quartz is a hardness of 7, and Diamond is a hardness of 10. The process is not actually cutting, but rather abrading, as the "cutting" edge grinds it's way through the material. Diamond coated tools will easily go through Quartz; just take your time and only apply gentle pressure and plenty of water to keep the blade cool and remove the Quartz particulate so the work area doesn't sludge up.
Question:	Will this cut 1/2" safety glass
Answer:	Dear valued customer Greeting! Yes, the diamond hole saw can cut 1/2" safety glass. Warmest regards StarQualityBargain Team
Question:	Why are these called "diamond hole saws" if they are made of corundum? corundum is not diamond
Answer:	Thank you for inquiry. The glass hole saw was coated diamond on the head for superior cutting strength. The description has been revised, thank you for your kindly reminding.
Question:	Do these go into a standard drill
Answer:	Dear valued customer Greeting! The diamond drill bits are compatible with most drills Warmest regards, StarQualityBargain Team

Answer:	3/16
Question:	Will this suit for drilling the fiberglass ?I afraid it will effect the perfect surface
Answer:	Hi Clinton. This is a standard-size, screw-on hose nozzle. It cannot be used to turn on/off water flow. It simply concentrates the water flow into a narrow stream, thereby increasing its power and reach. So, for example, you might use it to "power-wash" dirty siding on a house. --Tom

User questions & answers

Question:	What country is this made from
Answer:	I have a regular hose and have no issues. Try a coupling from Home Depot or any hardware store, that should work. This is a very good nozzle, although heavy.
Question:	Is the biggest hole bead the small number or the big number in millimeters
Answer:	We have never had to contact the company and we've been buying this sprayer for many years. In fact this one replaces my other Gilmour that I had for over 3 years.
