Choosing a Diamond Drill Bit

Consider the below points while choosing a diamond drill bit;

  1. Determine what material you are going to drill. Diamond drill bits are generally used to drill rock, glass, tile and other arduous materials. The shape of the drill bit is commonly determined by the fabric that it is going to be used to drill.
  2. Look carefully at how the merchandise is labeled. Do not just select the first diamond drill bit that you see. Some are clearly labeled for the use that they are supposed for, reminiscent of drilling glass.
  3. Choose the best diamond drill bit for your tool. Diamond drill bits are made for lapidary drills, common drills, and Dremels.
  4. Contemplate shopping for your diamond drill bits wholesale. Diamond drill bits do not have a long shelf life, as the heat generated from drilling will ultimately wear the electroplated diamonds off of the drill. If you’re planning on using your diamond drill bits for a lot of projects, it will save you money.
  5. Get pleasure from seeing your projects look very professional. You will also benefit from the time that you just save when you use the correct diamond drill bit.

Technical Considerations

  1. To drill a hole in the glass a person needs to understand that the only element harder than glass is a diamond and even so the project is not an easy one to complete.
  2. Low drilling speeds and plenty of coolant on the tip of the bit is required to achieve the desired result. Very little pressure must be exerted on the site, rather let the drill go at its own pace or the bit will overheat and the diamonds embedded in the tool will fall out making the bit useless.
  3. Making a well with normal glazing putty around the site of the hole and filling it with coolant is a common method employed when using drill bits for glass.
  4. Diamond core drill bits for glass grind or cut a hole at their outer edges of the tip rather than the center of the bit. As the circumference of a bit increases and the bit diameter gets bigger, the drill speed must be reduced to counteract the speed at which the outer cutting edge is moving. Diamond core bits are ideal for bigger and better holes in glass.
  5. Smaller pieces of glass may be drilled by submerging them in water for effective cooling.
  6. To prevent the bit from moving around at the beginning it may be necessary to use some form of the template to hold the bit in place when drilling glass. Another method is to use a patch of masking tape at the sited and making a pilot hole with a much smaller drill bit.
  7. There is a multitude of diamond drill bit manufacturers and some are better than others, but in general, any drill bit for glass for smaller applications and the handyman would do the job. For anybody drilling glass for the first time, it would be wise to practice on an off-cut first before attempting the actual cut, remember to wear eye and hand protection for your own safety as well.
