Description
Rotary Hammers 26mm (1")
CONCEPT AND MAIN APPLICATIONS
HR2600/ HR2601 are 26mm (1") 2-mode rotary hammers adapted for
SDS-PLUS bits, featuring compact and lightweight design, enhanced comfort
and better control with ergonomic handle. Model HR2601 is equipped with AVT;
Anti Vibration Technology consisting of Active dynamic vibration absorber
with counterweight and Damper spring. AVT ensures operation with
extremely low vibration, which is much superior to the competitors.
HR2600 series models are available in the variations listed below, including
HR2300 and HR2610 series models developed on the same concept.
