Stepped drill bit with unique SMART STEP technology and dynamically curved rake between the individual step transitions for extremely fast and comfortable use in all common materials with a material thickness of up to 3.5 mm.

Dynamically curved rake between each step transition


  • Significantly longer service life compared to conventional stepped drill bits

  • Significantly faster drilling compared to conventional stepped drill bits

  • Little effort required

  • Quiet, 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

  • Easy to drill holes or enlarge 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



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, the compact and practical system cassette features useful details such as stackability, an optimised joint and simple opening

Application area
  • The ideal tool for machining sheet metal.

  • Centring, spot drilling, boring and deburring of sheet metal, tubes and profiles in one operation, for use on both hand drills and stationary equipment.

  • Ideal for use in the electrical trade, plumbing and heating systems, automotive workshops, mechanical engineering, switch cabinet manufacturing or container and equipment engineering.
Instructions
  • Ensure that there is sufficient coolant/lubricant

  • Observe the rotation speed table

  • Do not push during drilling out. 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
04076
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).
