Cutting concrete requires the right tools and techniques to get the job done efficiently. Two common methods are hand sawing and ring sawing. While both are used to cut concrete, each has unique strengths. Choosing the right one depends on the depth of the cut, the material, and the project’s requirements. Understanding these methods helps in selecting the best option for accuracy, speed, and cost.
If you’re looking for concrete cutting solutions, knowing the differences between hand sawing and ring sawing can save time and effort. Let’s break it down.
Understanding Hand Sawing
Hand sawing is a versatile and portable method used for small to medium concrete cutting tasks. These saws are typically powered by electricity, petrol, or hydraulics, making them suitable for indoor and outdoor projects.
Key Features of Hand Sawing
- Precision cutting – Hand saws provide control, making them ideal for cutting straight lines or shaping openings.
- Portability – Their compact size allows for easy handling in tight spaces.
- Shallow cutting depth – Most hand saws cut up to 150mm deep, making them best for surface cuts.
Hand saws are commonly used for:
- Cutting concrete slabs, walls, and floors
- Removing small sections of concrete for repairs
- Creating expansion joints in sidewalks or driveways

Understanding Ring Sawing
Ring sawing is designed for deep concrete cutting where traditional saws fall short. Unlike hand saws, ring saws have a blade that rotates around its own axis, allowing for deeper cuts without needing a larger machine.
Key Features of Ring Sawing
- Deeper cutting capabilities – Cuts up to 270mm deep, making it ideal for thicker concrete.
- Minimal overcutting – The blade design allows for flush cutting without damaging surrounding surfaces.
- Fast and efficient – Higher speed and power mean quicker cutting in tough materials.
Ring saws are used for:
- Deep cuts in concrete walls and floors
- Creating openings for windows, doors, or vents
- Cutting reinforced concrete without excessive force

Key Differences Between Hand Sawing and Ring Sawing
Both methods serve specific purposes, but they differ in technique, depth, and application.
1. Cutting Depth
- Hand saws cut up to 150mm deep, making them better for surface-level work.
- Ring saws cut up to 270mm deep, handling thicker concrete slabs.
2. Precision and Control
- Hand saws offer better manual control for intricate cuts.
- Ring saws allow for cleaner, deeper cuts with less effort.
3. Speed and Efficiency
- Hand saws require more manual effort but are ideal for smaller jobs.
- Ring saws cut faster and deeper, making them efficient for large-scale projects.
4. Portability and Accessibility
- Hand saws are lightweight and easy to handle in confined spaces.
- Ring saws, while portable, require more skill and safety precautions.

Practical Applications of Hand and Ring Sawing
Choosing the right method depends on the project’s demands. Here are some real-world examples.
Example 1: Cutting Door Openings in Concrete Walls
A renovation project required cutting precise openings for new doorways in a concrete building. Hand sawing was used to create initial guide cuts, ensuring accuracy and control. However, the walls were over 200mm thick, requiring a ring saw to complete the cuts without overcutting the edges.
Example 2: Expanding Underground Utility Access
A construction team needed to enlarge underground service openings. Hand saws were used for surface scoring, followed by ring saws for deep penetration cuts, allowing precise removal of thick concrete slabs.

Which Method Should You Choose?
Deciding between hand sawing and ring sawing depends on:
- Project size – Hand saws work well for small cuts, while ring saws handle large, deep cuts.
- Depth requirements – If cutting beyond 150mm, a ring saw is the better choice.
- Surface conditions – Tight spaces may require hand sawing, but thick surfaces demand ring sawing.
Both tools have their place, and in some cases, using both methods together ensures the best results.
FAQs
1) When should I use hand sawing over ring sawing?
Hand sawing is best for projects requiring precision, shallow cuts, and tight-space access. It’s commonly used for floor joints, small openings in walls, and minor concrete repairs. Since hand saws are lightweight and easy to manoeuvre, they are ideal for jobs requiring detailed control. However, they have a cutting depth limit of around 150mm. If you need to cut deeper concrete slabs or walls, a ring saw is the better choice. Hand sawing is also preferred for indoor projects where large machinery isn’t practical due to space constraints or ventilation concerns.
2) Is ring sawing more expensive than hand sawing?
Yes, ring sawing typically costs more due to its advanced cutting technology, deeper penetration, and specialised blade system. The equipment itself is more expensive, and the high-powered operation leads to increased fuel or energy consumption. However, ring saws cut faster and deeper, reducing overall labour time. This makes them more cost-effective for large-scale projects where time efficiency is critical. If a project involves cutting thick, reinforced concrete, using a ring saw may be a better long-term investment despite the higher initial cost, as it speeds up work and reduces manual effort.
3) Can ring saws cut reinforced concrete?
Yes, ring saws are designed to cut through reinforced concrete, making them ideal for structural modifications, demolition work, and deep penetration cuts. Unlike traditional saws, ring saws generate higher power and torque, allowing them to slice through steel reinforcements embedded in concrete. Their unique blade design reduces the risk of overcutting, making them effective for precision structural work. This makes ring saws a preferred choice for cutting through thick walls, heavy slabs, or load-bearing structures where steel reinforcement is present. Their ability to handle both concrete and embedded metal makes them a versatile tool in construction.
4) What safety precautions should I take when using these saws?
When using hand or ring saws, wear protective gear such as gloves, safety glasses, hearing protection, and a dust mask to prevent inhaling fine concrete particles. Ensure proper ventilation, especially when using petrol-powered saws indoors, as fumes can build up quickly. Maintain a firm grip with both hands to prevent kickback or loss of control. Always inspect the blade before and after use for signs of wear or damage. Use correct cutting techniques to avoid injuries, and ensure the work area is clear of debris. Following these precautions significantly reduces the risk of accidents.
5) Can I use both hand sawing and ring sawing on the same project?
Yes, many professionals combine hand sawing and ring sawing for efficient and precise concrete cutting. Hand sawing is often used for initial scoring, marking out cuts, or making smaller adjustments, while ring sawing is utilised for deep, clean cuts. For example, when creating a doorway in a thick concrete wall, a hand saw might start the cut with precision, and a ring saw would complete the deeper sections. Using both methods ensures cleaner cuts, reduces overcutting, and speeds up the process, making them complementary tools in construction and renovation projects.
Find the Right Concrete Cutting Solution
Both hand sawing and ring sawing have their advantages. Hand sawing works well for precise, shallow cuts, while ring sawing excels at deep, efficient cutting. Understanding their differences helps in selecting the right tool for your project.
