Extra-long version with uneven stepped drill bit tip geometry for almost all materials

Advantages of the SMART STEP drill bit tip geometry with extremely uneven pitch (EU+)


  • Up to 50 % longer service life

  • Significantly more comfortable drilling with less vibration, even less effort and perfect tool guidance (up to 60 % less torque)

  • Up to 20 % lower energy consumption

  • Up to 15 % faster drilling progress


Precise, circular drill holes in almost all materials


  • Very precise drilling without tearing or splintering the material


Very comfortable drilling


  • No pre-drilling required despite the extra-long design

  • The tool does not run off-centre even when drilling particularly deep holes

  • Simple drilling or enlarging of an existing drill hole

  • No rattling or catching, even in thin-walled materials

  • Burr-free hole exit


Very fast drilling


  • Significantly faster and with less effort required compared to extra-long HSCo twist drill bits with conventional tip geometry


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


Available exclusively from WÜRTH



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

Notice
  • For blind holes, please be aware of the extended drill tip (see dimension l3)!

  • The innovative tip geometry drills step by step to achieve the required diameter. During the drilling process, multiple main cutting edges break up the chip into small individual chips for optimal chip removal. This ensures highly precise, circular drill holes.

  • The simultaneous use of several cutting edges ensures very fast, comfortable working and a long service life.

  • The service life can be significantly increased by using sufficient coolant and lubricant. This is strongly recommended especially when drilling stainless steel.

Application area
  • Ideal for use in cordless drivers as well as on hand-held, box column and pillar drills

  • For universal use in almost all materials, such as stainless steel (e.g. V2A, V4A), heat-resistant steels and titanium. Also for general applications in conventional steel up to 1,300 N/mm², as well as in cast iron, aluminium, plastic, non-ferrous metals, compact and hard wood and soft and light wood.

  • Significantly longer service life than long wood twist drill bits when drilling in wood.
Instructions

To achieve optimum drilling progress and avoid jamming, frequent "ventilation" of the drill bit is required for large drilling depths.
