Review on QWORK Hybrid Concrete Plastic Tungsten by Leo Govindan

HORRIBLE DRILL for drilling holes in glass. The drill breaks, breaks and cracks the glass. I work with stained glass and know how to cut glass. The photos below show what the drill did. I submerged the bottle and glass pieces under water while drilling. I didn't apply a lot of pressure, I just let the beat do its job. I have tried 3 bottles and this is the best. I've also tried drilling holes in small pieces of colored glass. It's hard to see in the photos, but you can see it cracking on the sides of the hole. I wouldn't buy these drills if you intend to use them on glass.
