Hand-held ring diamond blade wet saw for deep cuts (up to 135 mm) in concrete walls, masonry and stone — in stock at Multi Trade Combines, AT Road, Guwahati.
A ring saw machine is a specialist hand-held cutting tool for deep cuts in reinforced concrete, thick masonry walls, stone and other hard materials. The defining feature is its ring-shaped diamond blade: because the motor axis is perpendicular to the ring rather than at the centre, the ring blade can cut to depths of 130–135 mm with a manageable hand-held tool. This depth is unreachable with a standard angle grinder and requires a large walk-behind floor saw on flat surfaces. For vertical walls, piers, columns and floors where the saw must be operator-held and controlled — cutting a service penetration through a thick basement wall, opening a window in a concrete-block wall, removing a column section — the ring saw is the engineered solution.
Water supply to the blade is continuous during cutting: a hose connection keeps the blade at safe temperature and suppresses the silica-rich dust that concrete cutting generates. In Northeast India's fast-growing construction and renovation market, ring saws are used by specialist concrete cutting contractors working on apartment block modifications, infrastructure retrofits and controlled demolition projects in Guwahati and across the region. Multi Trade Combines stocks ring saws alongside the broader light construction machinery range at our AT Road, Guwahati counter — your single source for construction site equipment across the Northeast.

Service penetrations through reinforced concrete walls for pipes, cables and HVAC ducts — common in Guwahati's growing high-rise residential and commercial building stock — require precisely positioned round or rectangular openings through 200–300 mm thick walls. A ring saw makes these openings in a fraction of the time and with far less structural disturbance than hammer-and-chisel or percussion drilling methods. Bridge rehabilitation projects that require removing deteriorated concrete cover from reinforced structures use ring saws to cut exposure panels without damaging the underlying reinforcement. Stone quarry processors near Guwahati cutting natural stone blocks for architectural cladding use ring saws to produce deep, square-edged face cuts that diamond disc grinders cannot match in thickness. For projects needing a combination of deep hand-held cutting and floor joint cutting, the ring saw and slab cutter together from Multi Trade Combines provide the complete cutting toolkit.

A ring saw uses a ring-shaped diamond blade whose geometry allows deeper cuts relative to the blade diameter than a conventional circular disc — cuts of 135 mm depth are possible with a hand-held ring saw. This makes it practical for cutting through full-thickness concrete walls, deep masonry piers and thick stone slabs in one pass. An angle grinder with a 125 mm disc cuts only about 25–30 mm deep. For deep cuts in confined spaces where a walk-behind saw cannot be used, the ring saw is the specialist tool. Call +91 91812 13332 for availability.
Yes — concrete and masonry ring saws are wet-cut tools requiring a continuous water supply to the blade for cooling and dust suppression. The ring blade runs extremely hot at the cutting edge in dense concrete and will overheat and de-segment without water cooling. The water also wets the silica dust generated by cutting, preventing it from becoming airborne — an important health control for workers in enclosed spaces like basements, pipe trenches and enclosed room demolitions.
