***New Improved Design*** These 3.00mm x 100mm extra long shank, small diamond drill bits are ideal for drilling 3mm holes in hard materials such as glass, stone, ceramic, porcelain, shell, bone and fossils when the depth of the material requires an extra long shank to the drill bit. These long drill bits prevent your drill from hitting the material whilst drilling. 

Very popular with lapidarist, glass and stone artists, jewellers, restoration and conservation workers and Scientists. These long drill bits are solid throughout, not hollow.

"I especially find the extra long diamond drill bits helpful because I’m drilling through beach stones about 2 inches thick. I’m using a battery powered Dremel and placing the stones in water. When in water, the bits wear very well" - Andrew Honig

Other questions and our answers

Will your drill bits fit my drill?

Clare

Our drill bits will fit all rotary drills so long as you have an adjustable collet or chuck with which to hold the shank of our very small drill bits. Sometimes when buying a drill they will come with an adjustable collet but if you find you are in need of one then we supply either a Dremel Multi Chuck (DMC4486) or a Dremel Collet Nut Kit (DCNK4485).
