The high-performance stepped drill bit with unique SMART STEP technology, innovative rake between the individual step transitions and AlTiN coating for extremely fast, comfortable and long-lasting use in all common materials with a material thickness of up to 3.5 mm.

Innovative geometry with three chip surfaces between the individual step transitions

Up to 3x longer service life compared to all other coated stepped drill bits

Significantly faster drilling compared to all other coated stepped drill bits

Minimal effort required

Completely smooth, perfectly controlled drilling process

Greatly reduced formation of burrs

SMART STEP technology

Up to 3x faster drilling compared to conventional stepped drill bits

Precision drilling without centring or centre-punching

No warping of sheet metal

Simple drilling or enlarging of an existing drill hole

No rattling or catching in the material

Precise, circular drilling without tearing or splintering

Deep ground spiral groove

Excellent chip removal

AlTiN multilayer wear protection coating

Extremely high temperature resistance of up to 1,150°C

Very high coating hardness of 3,200 HV

Multilayer structure for optimal chip removal and improved cutting properties (prevents material becoming welded)

3-flat shank

No spinning in the drill chuck: faster, more comfortable working

Optimal power transmission

Protects the drill chuck from damage

Little effort required to open and close the drill chuck

Suitable for the ORSY^® system, compact and practical system cassette with useful details, such as stackability, optimised joint and simple opening

Available exclusively from Wurth

Notice

Cooling not absolutely necessary, but significantly extends the service life

Observe the rotation speed table

Do not push during boring. The stepped drill bit automatically retracts into the sheet metal.

Packaging unit

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.

Structure of our article number

The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076
