BOSCH step drill HSS 6 - 37 mm 10 mm 93 mm 12 steps 2608587428

The HSS stepped drill bit drills holes of various diameters smoothly and burr-free. It is ideal for drilling and enlarging holes. Center-punching is not necessary, as the cross-ground drill point makes drilling easier. The CNC-milled spiral flute optimally removes swarf and enables even drilling. Axial and radial relief grinding enable maximum cutting performance and absolutely smooth results. The step drill bit is suitable for thin material made of non-ferrous metal, stainless steel and plastic as well as sheet steel and plastic sheets. The step drill is made of HSS steel and is extremely durable when used with coolant. The easily recognizable and permanent diameter markings in both spiral flutes are lasered. The 3-face shank also prevents slipping in the chuck and enables high torques to be transmitted.
