DEWALT DT4957-QZ DT4957 HSS-Co 5 Metal twist drill bit set 29-piece high alloyed Triangular shank 29 pc(s)

The drill bits of the metal drill set DT4957 are characterized by a unique centering tip, which enables a precise drilling without slipping. Specially ground shoulder blades cutter precise, round bores with clean edges (from Ø 5 mm). An abrasion-protected size marking, which is placed outside the clamping range, provides for a permanent and good readability (starting from Ø 5 mm). The core reinforcement of the drill, with a constantly increasing core diameter in the shaft direction, ensures maximum fracture stability, especially in free-hand use. The drill also has an anti-slip shaft with three milled tooth areas that prevent the drill from spinning in the chuck and ensure optimum power transmission.
