Twist drill set Projahn HSS-R DIN 388, 25 short drills type N ECO, each 1 x Ø 1-13 mm, increasing by 0.5 mm, in plastic case

The HSS-R DIN 388 twist drill bit set from Projahn comprises 25 short, high-performance standard drill bits made of wear-resistant high-performance high-speed steel with diameters between 1 and 13 mm, whereby this increases in 0.5 mm steps. Thanks to a plug-in connection integrated into the shaft, they can be quickly replaced on the drill used entirely as required.

In addition, the drill bits, which are temperature-resistant up to 400° C, correspond to type N Eco - their roll-rolled normal spiral is characterised by high chip removal, good breakage resistance and excellent concentricity in the course of normal drilling work using common materials such as steel, cast iron, bronze, brass, graphite or aluminium.

You will receive the twist drill bit set HSS-R DIN 388 from Projahn in a practical, orange plastic case.
