Advantages

Drilling various diameters - The HSS step drill bit can make smooth, burr-free holes of various diameters with a single drill bit.
The drill bit is ideal for deburring, drilling round holes and enlarging existing holes.
Pre-punching is unnecessary as the split tip allows easy drilling.
The CNC ground spiral groove offers optimised chip removal and reduced vibration for uniform drilling.
Axial and radial back grinding ensure excellent cutting performance and absolute smoothness.
This step drill is suitable for use on thin materials, such as non-ferrous metals, sheet plastic, sheet steel, plastic and stainless steel.
The step drill is made of HSS (High-Speed Steel) and coated with AlTiN (aluminium titanium nitride).
This ensures maximum service life and eliminates the use of coolant.
Using laser, the hole diameters in both spiral grooves are clearly visible and durably marked.
In addition, the 3-surface shank prevents slipping in the chuck and ensures high torque transfer.
