Maximum comfort
- Designed for use with tangential impact drivers for even faster and safer work, as there is no back torque and therefore no strain on the wrist
- Extra-short version, similar to DIN 1897, for maximum stability and robustness
- Patent-pending SMART STEP tip geometry with extremely unequal pitch for drilling with minimal force and perfect tool guidance
Maximum service life due to nanoProtect coating
- Up to 8 times longer than our uncoated SMART STEP EU+ HSCo drill bit
- Up to 35 times longer service life than conventional HSS impact drill bits with coating
Maximum speed
- Up to 2 times faster than comparable twist drill bits with conventional tip geometry that are suitable for use with impact drivers
Maximum precision
- Precise, circular holes without tearing or splintering
- Precise spot drilling without running off centre, as well as simple boring or enlarging of an existing drill hole
Maximum flexibility in the application
- Can be used universally with almost all materials
- Can be used in tangential impact drivers as well as conventionally in drill/drivers or with box column and pillar drills
1/4 inch hexagon bit shank, type E
- Ground from solid material for the best possible concentricity and dimensional accuracy
- Secure hold and optimal power transmission in the drill chuck
- Extremely fast tool change in tangential impact drivers
- No snagging at the hole exit
Available exclusively from WÜRTH
Product packaging made from 100 % PCR (recycled plastic from household waste) and 100 % recyclable
- For use with 1/2 inch impact wrenches use only adapters specially designed for use with metal machining tools with 1/4 inch type E hexagon bit shank in conjunction with tangential impact wrenches. It is strongly advised against using any other adapter (e.g. for bits) as this could cause the twist drill bit to break.
- 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, the chip is broken into small individual chips by several main cutting edges, thus ensuring optimal chip removal. The result is 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 and when used with a tangential impact wrench.
Datasheets(X)
- Ideal for use in tangential impact drivers
- Ideal for use in cordless drivers as well as on hand drills, box column drills 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 1,400 N/mm², as well as in cast iron, aluminium, plastic, non-ferrous metals, compact and hard wood and soft and light wood.
- Perfect for drill holes in round tubes (e.g. in railing construction), for drilling out stud bolts, rivet holes, for drilling sheet metal and thin-walled profile materials
- Ideal for high-precision, comfortable and fast working in solid material
