Accurate step drilling across multiple sizes

Practical benefits

Multiple diameters in one: With twelve steps from 6 to 37 mm, you can drill, enlarge, and deburr holes without switching tools.
Extreme heat and wear resistance: The AlTiN coating withstands high working temperatures, giving you reduced friction and longer accessory life.
Effortless starts without pre-punching: The split-point tip and spiral flute allow you to start immediately with low vibration and smooth chip removal.

In a nutshell

The right choise for

With the Bosch HSS-AlTiN step drill bit, you can easily drill, enlarge, and deburr holes in thin materials such as sheet steel, stainless steel, non-ferrous metals, and plastics. Featuring twelve steps from 6 to 37 mm, it lets you tackle multiple diameters without swapping tools. The split-point tip centres immediately to prevent wandering, making pre-punching unnecessary. Its spiral flute ensures smooth chip removal, while the heat-resistant AlTiN coating reduces friction and extends service life significantly. Equipped with a 10 mm 3-flat shank to prevent slipping in the drill chuck, this step drill bit gives you full control and precision during installation work in control cabinets and cable pass-throughs.

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.
3-surface shank for drills.
