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 holes



Extremely comfortable drilling


  • Eliminates pre-drilling, precise spot drilling without running off-centre

  • Angled drilling possible

  • Simple drilling 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-held drilling up to dia. 20 mm without pre-drilling; even enables precise holes up to dia. 26.5 mm without pre-drilling when used in a box column drill


Shank reduced to dia. 12.7 mm from > 13.0 mm drill bit diameter for use in all standard 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

  • Minimal effort required to loosen and tighten the drill chuck


Product packaging made from 100 % PCR (recycled plastic from household waste) and 100 % recyclable

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

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
