Metabo Corporation has introduced three new brushless sds-max rotary combination hammers and two-new chiseling hammers designed for drilling or demoing concrete. These tools are powered by brushless motors, which means you will never have a brush changed again, as well as longer tool life and runtime. The motors are encapsulated preventing dust damage and enhancing the life of the tool.
The brushless sds-max rotary hammers are available in 1 9/16 in. KHEV 5-40 BL,1 3/4 in. KHEV 8-45 BL, and 2 1/6 in. KHEV 11-52 BL. The brushless chipping hammers are available in two models, MHEV 5 BL and MHEV 11 BL.
The rotary hammers have a mechanical safety clutch, which significantly reduces the chance of kickback should the bit bind in the work or hit rebar. Plus, both the gear and motor housing is die-cast in aluminum, which dissipates heat build-up, also aiding in the longevity of the tool.
Another key feature of these tools is the Metabo Vibration Technology (MVT) vibration dampening system; this includes a central handle that provides relief and helps protect the user from damaging vibrations. These hammers are also equipped with a new active vibration-absorbing counter-mass that goes against the hammering piston, absorbing most of the blow-back energy.
The new tools also include Vario-tacho-constamatic (VTC) full-wave electronics for maximum productivity. VTC is Metabo’s exclusive technology that maintains RPM under load thus enhancing the productivity of the tool; the drilling speed remains optimal in all circumstances. These tools also have other electronic features, such as soft start feature, overload protection, restart protection.
In addition, to help comply with the latest OSHA regulations on respirable silica, the hammers are compatible with Metabo's new dust collection shroud, the ESA-Max, which fits all the new Metabo hammers and adapts to all drilling and chipping applications.
