Bosch step drill HSS-TiN 6-39 mm

Drilling multiple diameters – The HSS step drill allows you to drill smooth, burr-free holes of different diameters with one and the same drill.
The drill is perfect for chamfering, drilling round holes and enlarging existing holes.
No prior marking is required as the split tip allows for easy drilling.
The CNC-ground spiral groove ensures optimized chip removal and reduced vibration for even drilling.
Axial and radial back grinding ensures excellent cutting performance and ultra-smooth operation.
This step drill is suitable for use on thin materials such as non-ferrous metals, plastic sheets, sheet metal, steel and stainless steel.
The step drill is made of high-speed steel (HSS) and coated with titanium nitride (TiN).
This ensures an exceptionally long service life, especially when using coolant.
The diameters of the holes are marked with a laser on the spiral grooves, which are clearly visible and wear-resistant.
In addition, the three-sided shank prevents the drill from slipping in the chuck and ensures high torque transfer.
