Very common with hobbyists, scientists, craftspeople, glass artists, fossil preparators, builders, plumbers, shopfitters and DIY enthusiasts.
These diamond core drill bits are used for drilling holes in bone china, porcelain plates, glass, ceramic, fossil, bone, mirrors, stone, concrete, brick, bathroom tiles and fish aquariums.
We have the right sizes for you if you are interested in purchasing just one diamond core drill bit for a DIY or craft project or hundreds of diamond drills as a professional tradesman.
Diamond drills for drilling tiles are essential and will drill holes far easier and with a smoother cut than any other tile drill bits.
Jewellers looking for diamond core drill sizes as small as 1mm - 3mm, please take a look at our Small Diamond Core Drills range . Alternatively, our most popular Small Diamond Drill Bits range has sizes from 0.75mm - 3mm here.
If you are using a hobby-type rotary tool such as a
Dremel
You can use the 3.5mm size in this range, or you might like to try our 3mm Small diamond core drills with a 2.7mm shank, or our 6mm Bottle Neck Diamond Core drills, which have a 2.35mm shank.
Helpful Note: The size indicated refers to the hole size you will achieve.
If you want to achieve a core rather than drill a hole, please see the technical tab for the internal diameter of each core drill. For example, if you need to extract a 3mm core, choose the 5mm diamond core drill bit.
Alternatively, use our Thin Wall Diamond Core Drills, which are specifically designed for extracting a core.
Tip: Use with plenty of cold water, slow speed and low pressure
Helpful note: If you find the drill bit skittering across the surface of your work, angle the drill to make the initial cut and then continue to drill vertically. Alternatively, you can adhere a piece of masking tape where you require the hole to be, or make a straightforward 'V' template out of a piece of wood similar to the one shown in our blog article ' How To Make a Stone Tea Light Candle Holder'

Disclaimer. Using rotary tools near water has never been, to the best of our knowledge, endorsed by any of the rotary tool manufacturers. If you choose to drill near water or with attachments under water connected to your drill, then you do so at your own risk. Please be aware that mixing electricity and water can be very dangerous.
