The extra-long deep hole drill with unique SMART STEP technology for high-precision circular drilling in hand-guided use in soft and hardwood, composite materials, steel up to 1000 N/mm², cast iron, aluminium, plastic, copper, brass and bronze

The first extra-long twist drill bit with stepped drill bit tip geometry



Precise, circular drilling without centre-punching



Up to 100 % faster than conventional extra-long HSS drill bits



Extremely comfortable drilling


  • Saves pre-drilling despite the extra-long design, precise tapping

  • Prevents the tool from running off centre even with particularly deep drilling

  • Significantly less effort required when drilling compared to conventional extra-long twist drill bits

  • Simple boring or enlarging of an existing drill hole


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

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

Application area
  • Ideal for drilling thin-walled composite materials, e.g. in window construction (plastic profiles with steel core)

  • High quality of drill holes and significantly longer service life compared to conventional wood boring bits.

  • Perfect for cordless drill drivers as well as handheld and pillar drill and drill presses

  • Universally suited for smooth as well as rounded and uneven surfaces

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).
