KENDO 10PCS Cement Drill Bit Set, 3/16"-1/2" Masonry Drill Bits Set, Tungsten Carbide Tip, Professional Concrete Drill Bit Set for Cement, Brick, Tile, Wood, Plastic, Glass and Ceramic Tile

Good product works well Great price

Me encantó este producto pues cumplió mis expectativas para realizar mis trabajos de mantenimiento pues consta de buen material de construcción

Good for the price, good for about three to four holes before bit comes dull and have to change bits.

These bits work well in porcelain wall tile and drill quickly. I haven't tried them on glass, but I don't see a need for that kind of work. Time will tell after I drill a number of tiles whether or not they'll be as durable as I hope they will be.

These did the same job as the very expensive one.

Recently had to mount a sign on a brick wall. These bits did the job!

great purchase.

Good quality the price is right
