Cordless rotary hammer PRDS 20‑20V

Steplessly drilling, screwing and hammer drilling with FlexPower multi-device battery 20V 4.0 Ah – including 3 x SDS drill bits

Mobile impact force for smashing results

Freedom of cordless use while drilling, hammer drilling and screwing – all with the cordless rotary hammer PRDS 20-20V. Weighs only 3 kg whilst offering a 20 V 4 Ah lithium ion battery of the Flexpower multi-device battery series. No matter if you need to penetrate hard rock, masonry, concrete or brick with the pneumatic hammer mechanism, or if you have to drill holes in wood, plastics, ceramics and metal. You can always rely on the enduring power of the handy cordless rotary hammer. The total impact energy is composed of a high impact frequency (5,000 hammer blows per minute) and a high impact force (2.0 joule) which allows to effortlessly drive in the 3 supplied SDS drill bits in the material to be processed. Completely without any physical effort, as it is the case for working with impact drills. This way, even overhead work can performed without tiring and nearly vibration-free thanks to the comparatively light weight of the rotary hammer.

Professionals already know: The softer a material is, the higher is the required speed. This is why the infinitely variable speed and impact control allows for an optimal adjustment of the impact and speed frequency to the hardness of the material to be processed. For screwing in or tightening and loosening screws, the PRDS 20-20V additionally comes with a switch for clockwise / counter-clockwise rotation.

The rotary selector switch is easily accessible and enables to switch between the following two operating modes:

  • Steplessly adjustable drilling and screwing in wood, plastics, ceramics, plasterboard or metal.
  • Steplessly adjustable hammer drilling in masonry, rock or concrete (no contact pressure required).

Premium branded battery for constantly full power

Premium branded battery

By now, lithium-ion batteries are widely distributed, after all they come without memory effect and self-discharge. Plus these batteries can be disconnected from the charger and used right away without it affecting the battery’s lifetime. But “lithium ions” is a generic term used for batteries of various qualities and made of diverse electrode materials; including those with a perceptibly weakening performance once the battery charge decreases.

Lithium-ion batteries supplied by Trotec are high-quality premium branded NMC batteries with a high energy density and charging voltage lasting until the end without exceptions – guaranteed! Compared to conventional lithium-ion batteries the performance of our premium branded batteries does not decrease even as the discharge increases.

Consequently, you benefit from lasting maximum power even with an almost empty battery. During longer operation only the battery charge decreases, never their performance – that is the added value of Trotec’s premium branded batteries!
