The TE 50-AVR is the newest in the Hilti SDS-max rotary hammer portfolio. From hammer drilling into concrete, masonry and stone, to chiseling and percussion coring, the TE 50-AVR suits multiple application needs optimizing user and tool performance on the job. The TE 50-AVR features Active Vibration Reduction (AVR), allowing you to work more comfortably without worrying about fatigue. The TE 50-AVR also features our new detachable cord. No longer will broke and worn cords be a concern. This cord snaps out when too much tension is applied and pops back in to reconnect. The TE 3-C is Hilti's solution for customers that need small drilling diameter ranges, as well as light duty chiseling application performance in an SDS+ rotary hammer. With the TE 3-C, you have the ability to perform multiple applications with the convenience of just one tool. The TE 3-C has an optimum hole diameter drilling range of up to 5/8 in. and maximum diameter drilling range up to 1-1/8 in., making a wide range of drilling applications possible. The TE 3-C provides the consistent, reliable drilling performance that Hilti is known for, while closing the gap for chiseling application needs in the SDS+ rotary hammer line.
