It is equipped with a 1500 W motor and accepts 125 mm cutting discs. The tool’s adjustable cutting depth and parallel cutting capability allow accurate slotting for different installation requirements, while its ergonomic housing supports extended use with improved control.

Advantages

The device combines high power with compact dimensions to deliver consistent cutting performance in brick, concrete and plaster. An adjustable depth control enables repeated, uniform cuts without frequent setup changes. Its ergonomic grip and balanced weight distribution reduce operator fatigue and improve handling during straight and curved cuts. Built-in dust extraction compatibility helps maintain a cleaner work environment and prolong consumable life.

Suitable for

• Cutting wall channels for electrical wiring and conduit installation
• Creating recesses for plumbing and piping in masonry and plaster
• Preparation of installation grooves for low-voltage cabling and communications wiring
• Renovation and retrofit work where precise, repeatable slots are required

Key specifications

• Rated power: 1500 watts for high cutting capacity
• Disc diameter compatibility: 125 millimeters
• Adjustable cutting depth for controlled groove dimensions
• Ergonomic housing with side handle for two-handed operation
• Dust extraction port for connection to an external vacuum

How to use

Secure the work area and mark the intended groove line on the wall. Fit a suitable 125 mm cutting disc rated for masonry and confirm it is tightened correctly. Adjust the cutting depth to match the required groove dimensions and attach the side handle for improved control. Start the tool and allow the motor to reach full speed before guiding the wall chaser along the marked line with steady, even pressure. For deeper grooves, make multiple passes at incremental depths rather than forcing a single deep cut. When finished, switch off the tool and wait for the disc to stop completely before setting the tool down and performing any cleanup.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask. Connect the dust extraction port to a vacuum designed for construction dust to reduce airborne particles. Match discs to the material being cut and replace worn discs promptly to maintain cutting accuracy. Allow the motor to cool during extended use periods and inspect the power cord and guards regularly for damage.
