Quick Answer

Use a ring saw when you need a deep horizontal or angled cut in concrete that a standard wall saw or hand-held saw can't reach — typically for door/window openings, pipe penetrations, and tunnel or shaft work. A ring saw drives a small continuous-rim blade around a ring guide, so the cutting edge extends 100-400 mm past the saw body. It's the tool for plunge cuts, tight corners, and deep horizontal penetrations in walls up to 500 mm thick.

Ring Saw vs Wall Saw

Feature	Ring Saw	Wall Saw (Track)
Cut depth	Deep — ring extends past body	Limited to blade radius
Footprint	Small — tight spaces, corners	Needs track and clearance
Horizontal cuts	Excellent — plunge and deep cuts	Good with track rotation
Setup time	Fast	Track mounting needed
Best for	Penetrations, chases, corners	Long straight openings

When to Choose a Ring Saw

• Cutting horizontal slots or penetrations in thick walls.
• Working in corners or confined spaces where a track can't fit.
• Plunge cuts for pipes, vents or conduit.
• Tunnel, shaft and reservoir work.
• When you need a clean, continuous edge in hard-to-reach spots.

Blade Selection

Ring saws use small-diameter continuous-rim diamond blades (200-400 mm) that run at high RPM. Choose a wet-cutting blade with a hard bond for reinforced concrete. Our laser-welded concrete blade handles standard wall saw work, while heavy reinforced walls benefit from the high-horsepower blade.

Safety Tips

• Ring saws have high torque — secure the machine before starting.
• Wet cutting is essential; dry ring sawing overheats small blades fast.
• Always support the cut-out section to prevent it falling and binding.
• Check for embedded utilities before cutting walls.

Frequently Asked Questions

Q: Can a ring saw cut through rebar?

A: Yes, with a hard-bond continuous rim blade. Feed slowly when hitting rebar.

Q: How deep can a ring saw cut?

A: Depends on the ring size — typically 150-400 mm deep in one pass.

Q: Ring saw or wire saw for thick walls?

A: For walls over 500 mm, wire saws are more efficient. Ring saws win on portability and setup speed.

Q: Do I need a special blade for ring saws?

A: Yes — use a continuous-rim blade rated for the ring saw's high RPM. Standard segmented blades can't handle it.
