Set di 7 punte da trapano adatte per piastrelle, vetro, cemento, pietra, mattoni, ceramica e specchi (3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm).

The sharp tungsten carbide drill bit can easily penetrate various materials (tile, concrete, brick walls, glass, mirror, masonry, and wood). When drilling hard materials (glass, tile, marble, or granite), please use water for lubrication. The U-groove design, made with a harder alloy head material, facilitates quick dust removal, and the triangular handle design provides greater stability during operation.
