Dremel Multi Chuck to hold the small shank of the drill bits
The small drill bits can be used in a standard rotary hand drill such as a Dremel, drill press, pendant motor or flexi shaft. You will need a collet kit or a multi chuck to hold these small drill bits in your drill as the shaft (the bottom of your diamond drill bit that goes into your drill) will be too small for the collet that is issued with your drill to hold.

The small drill bits should be used with a very small amount of pressure and are recommended to be used at low RPM levels and with plenty of cold water either via a drip feed system or slightly submerged. This will preserve the life of your drill bit and the material you're drilling through. Blackening of the tip, diamonds coming away from the shank or cracking in your material will all indicate one of the above or a combination of all three.
So remember: Slow Speed, Low Pressure, Cold Water

When drilling with a small diamond drill bit, you should always look to stay as safe as possible. This means that you should utilise eye and ear protection at all times when drilling in this manner. The sound of the drill going through hard materials is often likened to the sound of a dentist drill and you know how annoying and jarring this can be. Protecting your ears should make the process a much more comfortable one for you.
Obviously it's important to keep the main drill away from all contact with the water but with a drill bit, it is possible to pierce through your material without taking the rest of the drill into the water. If you find the material you're drilling extends the length of the drill bit so that your drill is touching your glass lets say then you may wish to try our Extra Long Diamond Drill bits.

Drilling Holes into Beads
Beads are an ideal way to personalise any chain or piece of jewellery so being able to drill a hole into a bead safely is a great boon for many people. If you are keen to create something truly unique, beads and the small diamond drill bit technology can make all the difference. If you already have some beads with holes in but your wire/chain or thread doesn't fit through, you may want to open up that hole using a diamond twist drill. The diamond grit runs along the edge of the drill so grinds away at the inside of your material smoothing out the inside and enlarging it for you.
