No other bit touches them

I dont know why I waited so long to buy the 1/4 " drygres bit. Makes drilling holes for shower doors on tile showers so much easier than using any other diamond bit you can put in your drill. Packed with wax to help with dissipate some of the heat. I used it for one shower and I ordered the 5/16" as that's another common size needed for shower doors.
