Twin-blade wall chaser cuts clean, flat-bottomed conduit channels in brick and concrete walls — essential for MEP fit-outs across NE India.
A wall chasing machine is a power tool that cuts two parallel channels into masonry walls simultaneously using twin diamond-tipped blades. The adjustable blade spacing and depth guide allow the operator to cut a clean, flat-bottomed groove of the exact width and depth needed to accommodate conduit, pipes, or cabling — then the wiring or pipe is pressed into the channel, secured with clips, and the groove is filled with plaster. The result is a flush, hidden installation with no visible surface conduit, the standard finish expected in modern residential and commercial construction.
In Guwahati's rapidly growing residential sector — multi-storey apartments in Bhangagarh, Beltola, Zoo Narengi, and satellite townships — MEP contractors use wall chasers to route electrical conduit and plumbing supply lines inside brick infill walls before plastering. The twin-blade action is several times faster than chiselling by hand and produces a consistently cleaner channel than a single-blade angle grinder, which makes a ragged-edged cut.
Electrical contractors doing first-fix wiring in apartment buildings and office fit-outs are the main users. They route PVC conduit in wall chases for lighting circuits, power points, switchboard connections, and data cabling. A good wall chaser lets a skilled operator complete the conduit routing for an entire apartment floor in a day — work that would take several days by chisel or angle grinder.
Plumbing contractors use wall chasers to embed hot and cold supply lines in bathroom and kitchen walls, eliminating surface-run pipe that is vulnerable to mechanical damage. Building renovation contractors working on older properties in Assam use them to upgrade wiring inside existing brick walls without major demolition.
The wall chaser works alongside other light construction machinery from our catalogue: the floor polishing machine for finishing works, the brick/block cutter for wall openings, and the concrete mixer for mortar and plastering. Dust extraction is strongly recommended — masonry dust from wall chasing is a silica hazard and a P2 respirator is the minimum personal protection during operation.

A wall chasing machine (also called a wall groover or wall chaser) cuts two parallel grooves in a masonry or concrete wall simultaneously, producing a clean flat-bottomed channel for embedding electrical conduit, plumbing pipes, or data cables. The twin-blade design makes channels in a single pass that would take multiple angle-grinder passes to achieve the same result. In Northeast India's apartment and commercial construction, wall chasers are used by MEP (mechanical, electrical, plumbing) contractors to route conduit and water supply lines inside walls before plastering.
Wall chasers are designed for brick, block, and unrcinforced concrete walls up to typical masonry hardness. Cutting reinforced concrete (slabs, columns, beams with rebars) is outside the design scope — the diamond blades can strike rebar, which causes dangerous tool kickback and blade damage. For cutting through RC slabs, a diamond core drill or a floor saw is the correct tool. If you need to chase a wall and suspect rebar is present, use a rebar detector or cover meter before cutting to map the bar positions.
