Rotary Hammer HAZET 9035-5 Keyless Black Blackberry

The Rotary Hammer HAZET 9035-5 Keyless Black Blackberry is a pneumatic rotary hammer designed for drilling small-diameter holes in concrete and other masonry materials. It features a keyless chuck for quick bit changes, operates at a rated speed of 3200 RPM, and achieves a maximum drilling diameter of 3 mm in concrete. The tool is powered by compressed air and has a measured sound power level of 97 dB. With a weight of 2.6 kg, it is intended for tasks that require controlled, high-speed rotary impact performance in compact form.

Advantages

The keyless chuck enables rapid and tool-free bit replacement, reducing downtime during repetitive drilling operations. The pneumatic drive provides continuous high-speed rotation at 3200 RPM, suitable for delicate or precision drilling tasks where small holes are required. The relatively low weight of 2.6 kg improves handling and reduces operator fatigue during extended use. The specified sound power level of 97 dB gives a clear indication of expected noise exposure so users can choose appropriate hearing protection.

Suitable for

• Drilling small-diameter holes in concrete and masonry (up to 3 mm)
• Precision anchoring and dowel installation in construction
• Maintenance tasks requiring quick bit changes and compact tools
• Work environments where pneumatic tools are standard

Key specifications

• Drive type: pneumatic (compressed air)
• Rated speed: 3200 RPM
• Maximum drilling diameter in concrete: 3 mm
• Sound power level: 97 dB
• Weight: 2.6 kg
• Chuck type: keyless

How to use

Connect the rotary hammer to a suitable compressed air supply following the hose and pressure recommendations of your workshop or compressor manufacturer. Select a drill bit appropriate for masonry or concrete and insert it into the keyless chuck until it locks securely. Position the tool perpendicular to the drilling surface, start the air supply and engage the trigger to begin drilling at the rated speed. Apply steady, moderate pressure—avoid forcing the tool—to maintain bit life and reduce wear. After drilling, depressurize the line before changing accessories or performing maintenance.

Recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection rated for the specified 97 dB sound level, and gloves. Ensure the compressor and air hose deliver the correct pressure and volume for safe operation. Regularly inspect the keyless chuck for wear and clean any debris to maintain secure bit retention. When working in confined or populated areas, consider additional noise mitigation measures.
