Step Drill Bit Step D.4-30mm Shank D.10mm L.100mm HSS blank 12 Steps BOSCH

The HSS step drill bit drills smooth, burr-free holes of various diameters. It is ideal for drilling and enlarging holes. Center punching is not required, as the drill tip with cross-grind facilitates drilling. The CNC-milled spiral flute optimally removes chips and enables uniform drilling. Axial and radial relief grinding allow for maximum cutting performance and absolutely smooth results. The step drill bit is suitable for thin non-ferrous metal, stainless steel, and plastic, as well as sheet steel and plastic panels. The step drill bit is made of HSS steel and is extremely durable when coolant is used. The clearly visible and permanent diameter markings in both spiral flutes are laser-etched. The 3-flat shank also prevents slipping in the drill chuck and allows for the transmission of high torques.
