Wall Chasers

Learn more about wall chasers

Wall chasers are specialised power tools designed to slice clean, dual grooves into masonry walls for flush-fitting cable conduits and pipework. Operating two parallel diamond blades on a single spindle, these tools allow tradespeople to set exact depth and width parameters before cutting, ensuring uniform channel dimensions across an entire site build. When paired with M-Class or H-Class dust extractors, modern chasers contain silica dust at the point of cut, keeping working environments safe, clean, and compliant with site health regulations. 

Typical uses

• Electrical first-fix: Cutting neat, uniform channels in brickwork and blockwork for PVC conduit and back boxes.

• Plumbing installations: Chasing out walls to recess microbore heating pipes, cold water lines, and waste outlets.

• Renovation & rewiring: Updating older domestic properties with concealed wiring runs without disrupting surrounding plasterwork.

• Structural repair: Cutting grooves into masonry joints to install helical reinforcing bars and bed joint reinforcement.

How to choose the right wall chaser

• Single disc versus twin disc: a twin disc wall chaser cuts both edges of the chase at once for straighter, cleaner trenches and less clearing out afterwards, while a single disc tool suits lighter, occasional runs.

• Power source: mains electric gives sustained power for concrete and long runs, battery models trade some runtime for cordless site access where trailing leads are not practical.

• Depth and width: check the tool's adjustable settings so you can set the chase to suit the cable, conduit or pipe you're burying.

• Blades: match the blade for the wall chasing machine to the substrate, choosing the right blade for wall chasing machine use in brick or concrete.

• Handling and control: look at handle layout, cutting control and overload protection, and factor in a dust extraction port to keep the work clean.

Before you order

• Confirm the material you're cutting and the chase size the service needs, whether that's concrete, blockwork or plasterboard.

• Check the blade type suits the substrate and that you've got the right accessories, including dust extraction.

• Plan for safe use with suitable PPE, a controlled work area and awareness of the electrical and plumbing chase requirements on site.

• Review fulfilment options such as Click & Collect or local branch stock so the tool is on hand when you need it.
