The monolithic widia plate increases the service life of the drill. The centering point allows you to start drilling quickly without the drill bit slipping. 3 symmetrically arranged cutting edges enable perfectly straight and axial drilling. The Widia insert with a rake angle of 135° allows drilling in reinforced concrete. Very deep embedding of the widia plate significantly improves the connection with the drill shank, which affects its high quality. 3 extraction surfaces and a special shape of the drill facilitate dust removal. Steel with a specification of 34CrNiMo6 ensures high strength and durability. Heat treated, thanks to which the hardness of the steel increases to 52 HRC, which ensures optimal resistance during operation. Drilling without damaging the substrate, even at the edges. Exceptionally high quality, cylindricality and axiality of the holes made, confirmed by the international SicherSafe certificate.
