The manually operated high-performance drill with unique SMART STEP technology (from dia. 2.5 mm) for high-precision circular drill holes in steel up to 1000 N/mm2, aluminium, plastic, non-ferrous metals, hard and soft wood.

The original SMART STEP: the first twist drill bit with stepped drill bit tip geometry (from dia. 2.5 mm)



Precise, circular drilling



Extremely comfortable drilling


  • Saves pre-drilling, precise tapping without running off centre

  • Angled drilling possible

  • Simple boring or enlarging of an existing drill hole


Significantly faster than conventional twist drill bits with point thinning



Ideal for drilling out rivets and stud bolts



The first twist drill bit to enable precise, hand-guided drilling up to dia. 20 mm without pre-drilling, and when used on a box column drill, even allows precise drilling up to dia. 26.5 mm without pre-drilling


From drill diameter > 13.0 mm, shank reduced to dia. 12.7 mm for use in all common 3-jaw drill chucks



3-flat shank (from dia. 4 mm)


  • 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

Notice

For blind bores, please note the extended drill tip (see dimension l3)!

Application area
  • Perfect for rivet holes, drilling out stud bolts, for drilling sheet metal and thin-walled profile materials (e.g. aluminium/window profiles).

  • High quality of drill holes and significantly longer service life compared to conventional twist wood drill bits for drilling holes in wood.

  • Ideal for high-precision, comfortable and quick work in solid materials (e.g. in steel with strength of up to 1000 N/mm², aluminium and plastics).

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:

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).
