  •   I like this tool.
By on
Pros : Enables quick and easy drilling of holes.
Cons : Can get jammed up with the glass plug it drills out. This creates a surface at the drill tip that blocks the tip of the drill from cutting into the glass.
Other Thoughts : I clean out the shaft chamber after each drill. A small piece of wire pushed down from the side opening should push the core of glass out the tip.

  •   Broke Off
By on
Pros : makes neat holes easily.
Cons : it snapped in two in the glass after little use. doesn't seem like a good value if breaks so quickly and easily. Too expensive for that result.
Other Thoughts : i am buying another one to give it another try.

  •   Long Life / Smooth Cut / Great for Glass
By on
Pros : This bit worked great with my flexshaft drill and fits the with my dremel as well. It makes a nice, smooth hole, even as the bit begins to dull. I was able to make over 30 1/8" holes in 3 mm glass per bit using water as a lubricant. I've tried other bits that haven't been able to handle the load of these bits. This is the only one I'll spend money on. Well worth every cent.
Cons : Would like to be able to get a quantity discount on these bit.
