Concrete and rebar go hand in hand. Reinforced concrete is the backbone of modern construction, which means any serious cutting job is going to involve metal. The big question is: can a concrete saw cut through rebar?

Yes, it can—but there are important things to understand before firing up the saw.

Understanding the Challenge of Rebar

Concrete is tough. Rebar is tougher. When you’re cutting through reinforced concrete, you’re essentially dealing with two different materials. Each has different resistance, structure, and heat dynamics.

Most concrete cutting services in Miami are well-equipped for this, but if you’re DIY-ing or hiring someone new, you need to ask the right questions.

What is Rebar Made Of?

Rebar (short for “reinforcing bar”) is typically made from steel. It’s embedded in concrete to add tensile strength. Without it, concrete would crack under tension.

Steel has a much higher melting point and density than concrete. So, when your blade hits rebar, you need the right tool, or you’ll burn out your gear fast.

Tools That Can Cut Through Concrete and Rebar

Not all concrete saws are built the same. Here’s a breakdown of what works best:

1. Diamond Blades

Diamond blades are the industry standard for cutting reinforced concrete. But not just any diamond blade will do. You need segmented or turbo blades specifically rated for cutting through both concrete and metal.

These are often labeled as “reinforced concrete blades.”

📌 Tip: Wet cutting is better for this kind of work. It reduces dust and keeps the blade cool, extending its life.

2. Cut-Off Saws / Concrete Saws

A gas-powered cut-off saw is the go-to tool for professionals. Paired with a high-quality concrete saw blade, it can chew through rebar without hesitation.

3. Wall Saws and Wire Saws

For deeper cuts or vertical surfaces, wall saws or wire saws are often used. These tools are more specialized and are part of advanced concrete cutting and coring services.

Why Blade Selection Matters

Choosing the wrong blade isn’t just inefficient—it’s dangerous. Using a masonry blade on rebar can:

• Snap the blade mid-cut
• Cause sparks and heat buildup
• Damage the saw’s motor

Always use blades designed for reinforced concrete. Brands label them clearly, so don’t skimp.

Will a concrete saw cut through rebar? Only if it’s equipped for the job.

How to Cut Reinforced Concrete Safely

Cutting through rebar isn’t just about tools. It’s about technique. Here’s a quick step-by-step:

Step 1: Prep the Area

Mark the cut zone. Remove debris and check for embedded utilities. If you’re doing slab cutting, verify thickness and reinforcement layout.

Step 2: Gear Up

PPE is non-negotiable:

• Eye protection
• Hearing protection
• Respirator (for dust)
• Gloves and steel-toe boots

Step 3: Make a Shallow Pass

Start with a shallow guide cut to avoid jamming the blade or overheating. This also gives you more control.

Step 4: Cut Through Concrete First

Let the blade do the work. Don’t force it. Use water to reduce dust and cool the blade.

Step 5: Cut Through Rebar

When you hit metal, slow down. The blade will spark. Maintain a steady pace. If necessary, switch to a metal cutting blade to finish the job.

Common Use Cases for Cutting Rebar

Concrete Demolition

In demolition jobs, cutting through slabs, beams, and columns often means dealing with thick rebar. Tools like hydraulic saws or core drills are essential.

Wall Openings and Door Cuts

Creating new openings in reinforced walls? You’ll need deep cutting capacity and tools like wall saws or slab cutters in Miami.

Utility Access

Need to access plumbing or electrical buried in reinforced flooring? Core drilling is the solution.
