CEMENT DRILL BIT DEXTER PRO DIAM 12MM, LENGTH 400MM, TRIANGULAR SHANK

Hexagonal shank wall drill bit DEXTER PRO L 400.0 mm Ø 12.0 mmSteel drill bit, hexagonal shank attack. Size: length 400mm Ø 12mm. This long concrete drill bit is ideal for drilling thick or hard-to-reach building materials (bricks, concrete blocks, concrete). Its triangular shank prevents rotation of the bit in the chuck and ensures better comfort of use. This shank allows it to be adapted to a standard chuck only. Due to its highly machined groove, dust is more easily evacuated, thus allowing more efficient drilling. The head, the groove and the technical nature of the materials used give this range of DEXTER PRO concrete drills a longer life multiplied by 3 compared to the standard range of DEXTER concrete drills. The percussion function is recommended for drilling solid materials, but should be avoided on hollow materials (drilled concrete blocks, drilled bricks).
