Onverwoestbaar!?

Bovenstaande beschrijving klopt 100 procent. Ik werk in een werkplaats voor bedrijfsvoertuigen en heb geprobeerd de TITAN-versie met 8 boren kapot te maken :) hij boort moeiteloos door tapeinden, remschijven van vrachtwagens, oude remtrommels. Het mooie is dat je start en niet' U hoeft geen gat te ponsen of voor te boren. Opstellen en aanvallen. Op een zaterdagochtend wilde ik het vernietigen, omdat ik gehard staal had gekregen. De boor had nu ongeveer 200 gaten geboord. Het stuk staal in de bankschroef was ongeveer 40 mm dik. De eerste paar millimeters moest hij worstelen met boor- en snijolie, maar daarna boorde hij een gat van ongeveer 2 cm diep en brak toen elke andere boormachine zou het opgeven of doorbranden tijdens het boren. 5 sterren en deze dingen zijn het geld zeker waard. Ik heb de 8 stuks onmiddellijk opnieuw gerangschikt... TOPPRODUCT zoals al uw producten
