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
Compact and practical system box suitable for the ORSY system with useful features such as stackability, optimised joint and simple opening.
Notice
- 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 drivers. 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 evacuation. 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.
- When using with an impact driver, make sure that drilling does not occur at too high a speed without impact. Allow the tangential impact to start as soon as possible. An adequate contact pressure adapted to the respective drill diameter supports the use of the impact function and prevents excessive cutting speeds. Do not drill at high speed without impact and do not increase the contact pressure until later, as this can lead to rapid overheating and premature cutting edge wear.
- The service life can be significantly increased by using sufficient coolant and lubricant. This is strongly recommended, especially when used with an impact driver and when drilling stainless steel and aluminium.
- Guide the twist drill bit as perpendicular as possible to the workpiece surface. Tilting can suddenly increase the load on the cutting edges, resulting in increased cutting edge wear or breakouts.
- On battery-operated machines, ensure that the battery is sufficiently charged and check its degree of ageing. A weak or worn battery can result in uneven cutting performance and a shorter service life.
Application area
Application area
- Ideal for use in tangential impact drivers.
- Ideal for use in cordless drivers as well as on hand, 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 1,400 N/mm², as well as in cast iron, aluminium, plastic, non-ferrous metals, compact and hard wood as well as 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.
