  •   Glastar Makes Best Bits
By on
Pros : I have never had any problems with any size of these bits by Glastar. They last well over 50x when used properly under water. Start the drill at a 45 degree angle, then straighten up. Let the weight of the drill do the pressing, go fast on the speed, but slow on the penetration. Change your water often!
Cons :
Other Thoughts : I trust this brand more than any I have ever used.

Pros : I've made a few holes with these and have not had any breakage.
Cons : You need a high-speed drill to take full advantage of these, although any drill will work - it will just take longer.

They are rectangular and stack well with a clear lid. Also, the soup containers to store frit (each size of frit in its own container stacked within the others of like color and only the top one needs a lid, and they are clear) Glass yogurt pots for storing frit and other bits Plastic containers that tubs of crystal light comes in for storing smaller pieces of glass.
