Maximum possible drilling precision, whether you are using a corded or cordless machine. When FEIN invented the first electric hand drill, more than 115 years ago, it revolutionized the world of work. The company's unique expertise in product development and its outstanding innovative ability are still reflected in FEIN brand power tools today. Both corded and cordless versions of the BOP product line drills are available, with identical performance specifications. Each individual part is designed for extreme durability and performance. This means that professional drilling operations can be performed with speed and precision, even under the toughest working conditions. The concentricity accuracy of the tools ensures high precision results. The maintenance-free brushless FEIN motor and FEIN lithium ion technology make the ABOP models achieve the same high performance as the BOP corded drills. The 18V lithium ion battery is the optimal combination of high performance capacity and low weight. The ABOP works at an extremely constant speed and its high efficiency ensures high-performance drilling, especially when drilling metal. Thanks to the single-collar drill chuck and spindle lock, the tool can be changed easily with one hand. The metal gearbox housing and high-quality metal rapid-clamping chuck guarantee high concentricity. The two-finger switch with electronic start provide the best possible way of controlling the speed. Thanks to their outstanding ergonomics and the comfort grip, the drills sit perfectly in your hand, creating the ideal conditions for working efficiently without getting tired.
