Easy centering: The special shaped tip design ensures accurate positioning and avoids skating on hard and smooth materials. Optimal dust removal: The large entrance channels remove the dust quickly from the hole for less wear rate on the tip resulting higher performance and longer lifetime. Precise round holes: Due to two extra carbide tips the drill bit will produce precise round holes and has also an excellent performance when hitting rebar. High energy transfer: The patented KVS-flute design gives the best energy transfer from the tool reception to the drill bit tip and also lowest vibration. Made in Germany.
