Whether the intended fastening project is chemical anchoring or mechanical anchoring. Both applications start at the same point, drilling as part of the borehole creation process. The quality and performance of a fastening at the end already significantly depends on this first application step. In order to achieve an optimum drilling result, the use of a high-quality drill bit should therefore not be dispensed with. Drills are not all the same and differ significantly from one another on the basis of a number of important quality features. Some relevant criteria are service life, heat resistance, compatibility or the basic drill design with regard to its cutting properties. Chemofast accompanies its customers fully from this first application step and supplies the Chemofast SDS drill bits in black high gloss that are suitable for the hammer drill. The extremely robust Chemofast SDS drill bits are compatible with all commercially available impact drills and hammer drills with SDS Plus quick-action drill chuck thanks to their SDS connection and promise fast drilling progress in concrete, reinforced concrete and masonry thanks to their 4-bladed carbide drill head. The improved double spiral design allows up to 25% faster drilling with optimum removal load & rapid drill dust removal even in deep drilling. All Chemofast drills are available individually in sizes 6 mm to 18 mm and in commercial lengths. In addition, there is a complete set consisting of the sizes 5 mm to 12 mm.
