What Is Ring and Chain Sawing?
Diamond floor cutting explained simply, so you know exactly what you are getting.
Ring and chainsawing uses hand-operated diamond sawing equipment to cut through concrete, reinforced concrete, brick, masonry, stone, and steel rebar. Both methods use diamond-tipped cutting systems to get through tough construction materials quickly and cleanly.
The key difference from other cutting methods is the ability to work where large machinery simply cannot fit. That is why ring/chain diamond cutting is the go-to solution for indoor renovations, basement works, tunnel structures, and any site with restricted access or low headroom.
At CA Drillers, we operate both systems and know exactly when to use each one. Our team carries up-to-date, well-maintained equipment, and every operator is fully trained and certified.
Why Contractors and Engineers Choose Ring and Chain Sawing
The advantages of chainsawing systems go beyond just cutting speed. Here is what makes these methods stand out on a live construction site:
No Overcuts
Unlike angle grinders or disc saws, ring and chain saws do not require overcuts at corners. You get perfectly square openings in a single pass, every time. This matters when you are working to tight tolerances or structural drawings.
Works in Confined Spaces
The ring & chain saw for tight spaces is designed specifically for low-headroom, narrow, or access-restricted environments. They are compact, hand-operated, and get the job done where bulkier equipment simply cannot reach.
Cuts Through Anything
Reinforced concrete, heavy rebar, brickwork, stone, or block, both ring and chainsaws handle them all. Chain saws cut to depths of up to 650mm. Ring saws reach up to 250mm. Between the two, no construction material presents a problem.
Low Dust and No Fumes
Both methods use wet cutting, which controls dust at the source. Ring saws produce no fumes, unlike conventional disc saws. This makes them suitable for live buildings, occupied facilities, hospitals, and sensitive sites.
Minimal Vibration
Lower vibrations mean less stress on nearby structures and less disturbance for the building or other people close by. This is particularly important when it comes to live-site renovations and heritage structures.
Fume-Free Cutting
Concrete cutting with a ring saw generates no emissions, which makes it safe to use in closed or poorly ventilated areas. An important benefit for basement, tunnel or underground construction projects.
Fast and Accurate
The most precise ring and chain cutting examples from our past projects consistently provide straight, clean cuts made faster than traditional methods. Speed without sacrificing precision is our standard that we adhere to.
Our 5-Step Ring and Chain Sawing Process
We keep things straightforward, from the first call to the finished cut.
1
Site Assessment
We review your drawings, visit the site if needed, and understand your access conditions, material type, and cut specifications before any work starts.
2
Method Selection
We confirm whether ring sawing, chainsawing, or a combination of both is the right approach for your project requirements.
3
Safe Setup
Equipment is positioned and secured. Wet cutting systems are connected. All ring and chainsaw safety protocols are followed before any cutting begins.
4
Precision Cutting
Cuts are made to your exact dimensions. Our technicians work to the specification, not in opposition to it. Clean edges, square corners, and no damage or structural issues to the surrounding material.
5
Clean Finish and Sign-Off
The site is cleaned of debris and water, then the site is removed, and the area is ready to be used for the next job. We will not stop until the job is completed to our standards.
Technical Specifications
Our equipment covers a wide range of deep ring saw applications and heavy concrete cutting tasks:
- Diamond chainsaws: cutting depth up to 650mm through reinforced concrete, rebar, brick, and stone
- Hydraulic diamond ring saws: cutting depth up to 250mm through all construction materials, including heavy steel reinforcement
- Diamond chain blades for construction: diamond-segment chains designed for controlled, straight cuts without chipping or cracking adjacent material
- Both systems operate using wet cutting to suppress dust and control debris.
- Low vibration output, safe to use in sensitive or occupied structures
- is suitable for horizontal, vertical, and angled cuts
- Small enough to fit in tight areas, basement levels, tunnels, and low clearance areas
- Hydraulic systems guarantee constant power output, regardless of the cut depth or density of the material.
- No generator noise or exhaust fumes, both systems are suitable for indoor use.

What Our Clients Say
Frequently Asked Questions
What is the difference between ring sawing and chainsawing?
Ring saws utilise circular diamond blades that are attached to a hydraulic ring and are perfect for making openings in floors, walls and ceilings as deep as 250mm. Chain saws are made of a diamond segment chain that is similar to a chainsaw. They are able to cut up to about 650mm. Chain saws are generally employed for structures that are thicker or in situations where a longer cut is needed.
Can you cut through steel-reinforced concrete?
Yes. Both our ring saws and chain saws cut through heavy-duty steel reinforcement bars without issue. The diamond-tipped cutting systems are designed specifically for reinforced concrete.
Is ring and chainsawing suitable for occupied buildings?
Yes. The process of cutting wet wood generates very little dust, and ring saws work without the emission of fumes. The vibration levels are lower when compared to conventional cutting techniques. We often perform live cutting on locations, such as hospitals, offices and residential properties.
Can you work in a basement or an underground environment?
Yes. The compact, hand-operated design of both ring and chainsaws makes them well-suited for confined spaces, low-headroom areas, basement levels, and underground structures.
Do I need to provide water for wet cutting?
We bring everything needed for a wet cutting setup. You do not need to arrange a water supply separately unless site access conditions are unusual, in which case we will discuss this with you at the quote stage.
How quickly can you get to the site?
We provide fast response times across London and South East England. Call us on 0808 258 2223 for availability on your specific project dates.
What is ring and chainsaw safety on-site?
Our operators follow strict safety guidelines that cover inspection of equipment, personal protection devices, management of the water and working from a height or in enclosed spaces where necessary. Every job is in compliance with applicable CDM in addition to health and safety laws.
