Review on Efficient And Precise: Mgtgbao 8PCS Green Diamond Drill Bits Set For Granite, Marble, Tile, And Glass by Joshua Romero

Revainrating 4 out of 5

Okay for occasional use.

These are handy to have available. I used the 3/16 to install a shower door on tile. It was 6 holes for the frame. I could tell it was wasn't cutting on the last holes as good as on the first one. Still worked and still has life. Not an everyday bit set but I have others to use A variety of sizes means I may have what I need for a one time need.

Pros
  • ☪Upgraded Dry Drilling Design : Mgtgbao Diamond Drill Bit integrated with wax lubricant inside which melts while dry drilling and cools the cutting surface; Water can be used as additional cooling to prolong the life of the bit. Surface plating can prevent the drill bit from rusting.
Cons
  • The set may cause undue fatigue due to the need for precision and control
