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 tapping compared to conventional stepped drill bits

  • Precision tapping without centring or centre-punching

  • No warping of sheet metal

  • Simple boring or enlarging of an existing drill hole

  • No rattling or catching in the material

  • Precise, circular drilling without tearing or splintering


Deep-ground spiral flute


Excellent chip removal



AlTiN multi-layer wear protection coating


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

  • Very high coating hardness of 3,200 HV

  • Multi-layer 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 loosen and tighten the drill chuck


Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze



Available exclusively from Würth

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.

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.
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

Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
