Step drill set with spiral
Sets in box
HSS TiN
Application: Advantage:
For drilling and simultaneous deburring in steel,  Twisted design ensures smooth cutting behaviour
stainless steel, non-ferrous metals and cast iron.  No catching on the cutter and low cutting forces
Execution: and torques
 Profi le-ground and twisted cutter  High variability: A wide range of bores can be
covered with just one tool
 Ident. No. 800, 900: 3-facet shank ensures good Ident. No. 900–905
torque transfer in the chuck
