This HSS PointTeQ range of metal drill sets from Bosch® is designed for professionals.<CRLF>Each self-centering drill bit prevents the drill from slipping on the workpiece and ensures easy and quick pilot drilling. This results in a faster drilling rate compared to other entry-level metal drills. Regardless of whether you want to make clearance holes for screwed connections, cable and pipe transits or core holes for threads and rivet joints: All common metal applications for hand-held drills can be performed quickly and efficiently.<CRLF><CRLF>The fast drilling rate of the HSS PointTeQ reduces friction with the material. The tip heats up less than comparable metal drills with standard grinding. It does not become blunt as quickly and the wear-and-tear is reduced - this ensures higher productivity and a longer lifetime for the metal drill. <CRLF><CRLF>Furthermore, the drill flute is oxide-coated to vastly reduce friction, and therefore speed up chip removal - making drilling much easier and speeding up the work progress.<CRLF><CRLF>Features and Benefits<CRLF>• New design provides a fast drilling rate for professionals<CRLF>• Self-centering "PointTeQ" drill bit enables simple and fast drilling<CRLF>• Reduced friction and quick chip removal thanks to flute with oxide coating<CRLF>• Reduced wear-and-tear and a long lifetime thanks to higher drilling speed<CRLF>• Supplied in a plastic case for easy storage and organisation<CRLF><CRLF>Contents<CRLF>• BCH2806372M - 1 x 1 to 10mm in increments of 0.5mm<CRLF>• BCH2806372S - 1 x 1 to 13mm in increments of 0.5mm<CRLF><CRLF>Material Applications<CRLF>• Aluminium<CRLF>• Cast iron<CRLF>• Metal pipes and profiles<CRLF>• Non-ferrous metals<CRLF>• Plastics<CRLF>• Steel<CRLF><CRLF>Standards<CRLF>• Manufactured to DIN 338
