Can I cut concrete with an angle grinder?

Yes — an angle grinder with a diamond blade can cut concrete up to about 1.5 inches deep (4.5-inch blade) or 2.5 inches deep (7-inch blade). For deeper cuts, you need a concrete saw.

Can I break concrete with a hammer and chisel?

Yes, for small sections. Score a line with a cold chisel and hammer, then break along the score. This method is slow and imprecise but requires no power tools.

What's the cheapest way to cut concrete?

A 4.5-inch angle grinder with a $10-15 diamond blade is the cheapest power tool option. For no-power-tool jobs, a cold chisel and 3-pound hammer works for breaking small sections.

How to Cut Concrete Without a Saw (5 Methods)

Don’t have a concrete saw? You can still cut concrete without a saw using several alternative methods. This guide covers five practical approaches — from angle grinders to hammer-and-chisel — with a comparison table so you can pick the right method for your project.

Method 1: Angle Grinder with Diamond Blade

The best alternative to a concrete saw. A standard angle grinder with a 4.5” or 7” diamond blade can cut concrete up to 1.5” deep (small grinder) or 2.5” deep (large grinder). This is the method most contractors use when a full-size concrete saw isn’t available or practical.

Pros: Fast, relatively precise, affordable. Cons: Limited depth, significant dust. Best for: Scoring lines, cutting pavers, small concrete sections, rebar.

Method 2: Circular Saw with Diamond Blade

A standard circular saw fitted with a 7.25” diamond blade can cut concrete without a saw up to about 2.5” deep. This works in a pinch if you already own a circular saw. Use a blade specifically rated for masonry — never use a wood blade on concrete.

Pros: Deeper cut than a small angle grinder, guided by shoe plate. Cons: Not designed for concrete (motor strain), heavy dust, blade guard doesn’t seal for dust collection. Best for: One-time cuts when you don’t want to buy a dedicated saw.

Method 3: Hammer Drill with Chisel Bit

A rotary hammer drill with a chisel bit (SDS-Plus or SDS-Max) can break concrete along a scored line. Score the line first with an angle grinder or cold chisel, then use the hammer drill to break the concrete along the score. This is slower than cutting but effective for removal work.

Pros: No blade needed, good for removal/demolition. Cons: Imprecise edges, slower than cutting, vibration. Best for: Breaking out sections for removal, not precision cutting.

Method 4: Hammer and Cold Chisel (Manual)

The oldest method. Score a line with a cold chisel and 3-pound hand sledge, then deepen the score until the concrete fractures along the line. Extremely slow on thick concrete but requires zero power tools.

Pros: No power tools needed, cheap. Cons: Very slow, imprecise, physically demanding, only practical for thin concrete or small sections. Best for: Removing a single paver, breaking a small section of sidewalk, or when no electricity is available.

Method 5: Wedge-and-Feather Splitting

Drill a series of holes along the cut line with a hammer drill, then insert wedge-and-feather (plug-and-feather) sets. As you drive the wedges, the concrete splits along the drilled line. This method is used in stone quarrying and works well on thick concrete where other methods can’t reach.

Pros: Can split very thick concrete, relatively precise, no dust. Cons: Requires drilling many holes, specialized hardware, slow setup. Best for: Thick concrete sections where cutting isn’t practical.

Comparison Table: How to Cut Concrete Without a Saw

Method	Speed	Precision	Max Depth	Cost	Dust
Angle grinder + diamond blade	Fast	Good	1.5”-2.5”	$30-50 (blade)	High
Circular saw + diamond blade	Medium	Good	2.5”	$20-40 (blade)	High
Hammer drill + chisel	Medium	Fair	Unlimited	$0 (if owned)	Low
Hammer + cold chisel	Slow	Poor	4-6” practical	$15-20	Low
Wedge-and-feather	Slow	Good	Unlimited	$50-100 (set)	None

Which Method Should You Use?

For most people trying to cut concrete without a saw, an angle grinder with a diamond blade is the answer. It’s fast, affordable, and produces clean enough cuts for most residential and light commercial work.

If you need to cut deeper than an angle grinder allows, either rent a concrete saw (usually $50-80/day) or use the score-and-break method: cut as deep as your grinder allows on both sides, then break the concrete along the scored line with a hammer.

Important: All concrete cutting generates silica dust. Wear at minimum an N95 respirator, and use a vacuum shroud on your grinder if working indoors. See our Silica Dust Safety Guide.
