User questions & answers

Question:	Can these be used with a Dremel
Answer:	These are designed to work with a slow moving drill and I believe a Dremel spins way too fast to use these. Also I think the shaft diameter is too large for that. So, my opinion is "no" not with a Dremel".
Question:	Do I have to use some sort of adapter? The jaws of my screw gun do not open wide enough for the larger bits
Answer:	You shouldn’t have too. Only if your drill doesn’t have a stander chuck. 3/8 or 1/2 chucks are used on many types of hand held drills.
Question:	Has anyone used this on granite
Answer:	Will not work on Granite. These are too small
Question:	This product says ...Will automatically vomit and not easy to burst. What does that even mean? It is on the pictures for the product
Answer:	The automatic Vomit feature is enabled by default- it is projectile so you wont have to worry about the burst vomit mess... instead its a steady upchuck stream.... actually this is nonsense really. I'm sure its just a hilarious mistranslated document.

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.
