The universal SMART STEP twist drill bit with patent-pending stepped drill bit tip geometry with extremely uneven pitch (from dia. 2.5 mm) for even faster, more comfortable drilling with unrivalled precision and service life

Extremely unequal pitch (EU+)

Up to 50 % longer service life

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

Up to 20 % lower energy consumption

Up to 15 % faster drilling progress

Precise, circular drilling in almost all materials without tearing or splintering

Extremely comfortable drilling

Precise tapping without running off centre

Simple boring or enlarging of an existing drill hole

Angled drilling possible

No rattling or catching - even in thin-walled material

Burr-free hole exit

Significantly faster and more energy-efficient drilling compared to conventional HSCo twist drill bits

The first twist drill bit to enable precise, hand-guided drilling up to dia. 20 mm without pre-drilling

Shank reduced to dia. 12.7 mm from > 13.0 mm bore diameter for use in all standard three-jaw drill chucks

Ideal for drilling out rivets and stud bolts

Ideal for drilling in round material or pipes with stringent requirements for centring, precision and service life, e.g. in railing construction

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

Available exclusively from Würth

Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze

Notice

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

The steps of the innovative point geometry drill gradually to achieve the required diameter. To achieve this, the chip is broken into small individual chips by several main cutting edges, thus ensuring optimal chip removal. The result is highly precise, circular drilling.

The use of several cutting edges at the same time enables very fast, comfortable working and a long service life.
