Martello perforatore Metabo KH 5-40 1100 W 650 giri/min SDS Max

The Metabo KH 5-40 (600763500) combination hammer is an SDS Max rotary hammer with a 1100 W motor, designed for heavy-duty drilling and chiselling in concrete and masonry. It delivers up to 8.5 J impact energy, supports drill diameters up to 40 mm in concrete and runs at a rated speed of 650 RPM. The tool features a robust die-cast aluminium gear housing for improved heat dissipation and long service life, an S-automatic safety clutch for mechanical decoupling if the drill jams, a 4 m power cord and a total weight of 7.1 kg.

Advantages

The Metabo KH 5-40 combines high impact energy with a 1100 W motor to handle demanding hammer drilling and chiselling tasks. The Metabo S-automatic safety clutch reduces the risk of sudden torque reaction by mechanically decoupling the drive if the tool jams. A die-cast aluminium gearbox housing improves heat dissipation and contributes to longer service life, while the SDS Max interface provides reliable bit retention for heavy-duty use.

Suitable for

• Hammer drilling in concrete and masonry (up to 40 mm)

How to use

Fit an SDS Max bit appropriate for the task and ensure it is fully seated in the chuck. Select the required function—hammer drilling or chiselling—using the mode selector. Hold the tool with both hands, start at low speed to establish the hole, then apply steady pressure while maintaining control; avoid forcing the tool. If the bit jams, release the trigger immediately to allow the S-automatic safety clutch to activate. After use, clean the bit and tool, and store in a dry place.

Recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask and gloves). Match the drill bit type and size to the material and hole diameter. For prolonged drilling in reinforced concrete use intermittent operation to limit heat build-up. Regularly inspect the power cord and housing for damage and follow Metabo service intervals for maintenance.
