MAKITA Rotary hammer HR4511C SDS-Max

Special features
Highly versatile SDS-Max hammer drill and breaking hammer with excellent impact strength / weight / vibration ratio.
Equipped with patented AVT system with active counterweight and shock-absorbing handle for minimum vibration and high operating comfort.
Within the current standards, this machine can be used two to six-times longer than other comparable machines.
Electronically adjustable stroke power and frequency.
Asynchronous stroke distribution leads to faster drilling progress and easier drilling of reinforced materials.
The pressure loss system prevents the hammer mechanism from operating at no load, protecting machine and user.
The robust roller slip clutch offers more comfort and a longer service life when drilling in reinforced concrete.
The patented zigzag coating protects the armature windings against damage caused by sand circulated in the cooling air.
Extremely robust crankshaft and transmission bearings, held on both sides in a layered magnesium die-cast crankshaft housing.
The function reverse button can be rotated through 360° to make it easier to use and is protected from damage by its shielded position.
Equipped with carbon brushes that automatically shut off and a service indicator before failure occurs.
