Hacksaws are for cutting tougher materials like metal and plastic with a sturdy frame and coarse teeth, while coping saws excel at intricate curves in softer materials like wood with a thin blade and adjustable frame. Choosing the right saw ensures cleaner cuts and less frustration for your DIY projects.
Hey there, DIYers! Ever stood in the tool aisle, staring at two very different saws, and wondered, “What’s the real deal with these?” It’s a common question, especially when you’re just starting out or tackling a new project. You’ve got the robust hacksaw, built for serious business, and the nimble coping saw, ready for delicate work. They look similar enough, but use them on the wrong job, and you’ll end up with jagged edges, a broken blade, or a whole lot of frustration. Don’t worry, we’ve all been there! Today, we’re going to break down the essential differences between a hacksaw and a coping saw, so you can pick the right tool for the job and cut with confidence. Let’s get started!
Understanding the Basics: What Exactly Are These Saws?
Before we dive into the nitty-gritty of their differences, let’s get a clear picture of what each saw is designed for. Think of them as specialized tools in your cutting arsenal, each with its own strengths.
The Mighty Hacksaw
A hacksaw is your go-to tool for cutting through harder materials. Its name even hints at its primary purpose – cutting metal, especially pipes and rods. But it’s not just for metal! You can use a hacksaw for cutting plastics, threaded rods, and even some types of harder wood if you have the right blade.
The defining feature of a hacksaw is its rigid, C-shaped frame. This frame holds a relatively thick, stiff blade under tension. The blades themselves are typically narrow, with fine teeth that are designed to efficiently remove material from dense substances. Because the frame is solid and doesn’t offer much adjustability, the blade is usually fixed at a standard length.
The hacksaw is all about power and durability. It’s built to withstand the pressure needed to cut through tough stuff. When you’re cutting a metal pipe for plumbing or trimming a plastic conduit, the hacksaw is your reliable workhorse.
The Delicate Coping Saw
Now, let’s talk about the coping saw. This is a much more delicate tool, designed for precision and intricate work, particularly in softer materials like wood. Its name comes from its traditional use in woodworking: cutting “copes” or joints in decorative molding, where precise angles and curves are essential.
The key difference you’ll notice immediately is the frame. A coping saw has a much lighter, often U-shaped frame, which is usually adjustable. This adjustability allows you to fit different lengths of blades. The blades themselves are incredibly thin and flexible, with very fine teeth. This thinness and flexibility are what allow the coping saw to navigate tight curves and intricate patterns without binding or breaking.
Because the blade is so thin and the frame is so light, a coping saw isn’t designed for brute force. Instead, it relies on a smooth, controlled sawing motion. If you need to cut a decorative shape into a piece of plywood, create a small internal curve in a workpiece, or even do some intricate fretwork, the coping saw is your star player.
Key Differences: Hacksaw vs. Coping Saw
Let’s get down to the nitty-gritty. While both are hand saws, their design, intended use, and performance are quite distinct. Understanding these differences will help you choose the right tool and avoid common mistakes.
Frame Design
The frame is perhaps the most obvious differentiator:
- Hacksaw Frame: Typically a rigid, closed C-shape. This sturdy design provides excellent support for the blade, allowing for more pressure to be applied during cuts. The rigidity helps prevent the blade from flexing or bending, which is crucial when cutting harder materials.
- Coping Saw Frame: Usually a lighter, U-shaped frame. This frame is often adjustable, allowing you to tension different lengths of blades. The open design of the U-shape, along with the thinner frame, makes it easier to maneuver the saw through tight spaces and around curves.
Blade Characteristics
The blades are where the real magic (or disaster) happens if you choose the wrong one:
- Hacksaw Blade: Thicker, stiffer, and wider than a coping saw blade. They come in various lengths (commonly 10 or 12 inches) and have a higher tooth count (TPI – Teeth Per Inch) for cutting metal. For softer materials like wood, you can find hacksaw blades with lower TPI. The teeth are usually set straight.
- Coping Saw Blade: Extremely thin, narrow, and flexible. These blades are designed to bend and twist without snapping. They have very fine teeth, suitable for cutting soft woods, plastics, and thin metals. The teeth can be set straight or have a slight offset to help clear sawdust and prevent binding on curves.
Intended Materials
This is where their purposes really diverge:
- Hacksaw: Primarily designed for cutting metals (steel, aluminum, copper), hard plastics, and pipes. With the right blade (lower TPI), it can also cut through thicker woods, but it’s not its specialty.
- Coping Saw: Best suited for cutting curves, intricate shapes, and internal cutouts in softer materials like wood, plywood, MDF, and thin plastics. It can cut very thin metals with the appropriate blade, but it’s not efficient for straight, heavy-duty cuts.
Cutting Action and Precision
How they cut and what kind of results you can expect:
- Hacksaw: Employs a push-stroke action, where the cutting happens as you push the saw forward. The rigid blade and frame allow for a powerful, straight cut. It’s not designed for intricate curves.
- Coping Saw: Uses a pull-stroke action, meaning it cuts on the pull stroke, though many modern blades are designed to cut on both push and pull. The thin, flexible blade allows for excellent maneuverability, making it ideal for detailed work and tight turns.
Blade Tensioning
How you set up the blade is important for performance:
- Hacksaw: Blades are tensioned by tightening a wingnut or screw at the end of the frame. You want the blade to be taut, like a guitar string, to prevent it from bending or breaking.
- Coping Saw: Blades are tensioned using a mechanism on the frame, often a screw or a lever. The key here is to tension the blade so it’s straight and firm enough to cut cleanly, but not so tight that it snaps under the stress of a curve. Some coping saw blades can also be rotated to change the cutting direction relative to the frame.
When to Use Which Saw: Practical Applications
Knowing the differences is one thing, but seeing them in action is another. Here are some common DIY scenarios where one saw clearly shines over the other.
Hacksaw in Action
Think of the hacksaw when you need to:
- Cut metal pipes for plumbing or DIY projects.
- Trim threaded rods to length.
- Cut through plastic tubing or conduit.
- Make straight cuts in thicker, harder materials where precision isn’t paramount.
- Remove old, rusted bolts or metal components.
For instance, if you’re installing a new shelf and need to cut a metal bracket to size, the hacksaw is your tool. Its sturdy frame and blade can handle the resistance of the metal, giving you a clean, straight cut with the right technique.
Coping Saw in Action
Reach for the coping saw when your project demands:
- Cutting decorative curves or intricate shapes into wood.
- Making internal cutouts, like for a sink in a countertop or a decorative inlay.
- Creating precise joints in molding or trim work.
- Cutting tight-radius curves in plywood or thin hardwoods.
- Fretsaw work or detailed model making.
Imagine you’re building a custom birdhouse and need to cut out a small, arched doorway. The coping saw, with its ability to turn on a dime, is perfect for this kind of detailed, curved work. You can guide the thin blade precisely through the wood to achieve the desired shape.
Choosing the Right Blade: The Secret to Success
We’ve touched on blades, but it’s worth emphasizing. The blade is the cutting edge, and its TPI (Teeth Per Inch) is critical. A general rule of thumb for hand saws is:
- High TPI (18-32 TPI): For harder materials like metal and hard plastics. More teeth per inch mean smaller, finer teeth that create a smoother cut and remove less material, which is good for dense substances.
- Low TPI (14-18 TPI): For softer materials like wood. Fewer, larger teeth remove material more aggressively, preventing the saw from clogging and binding.
When selecting a blade, always consider the material you’ll be cutting. For a hacksaw, if you’re cutting wood, opt for a lower TPI blade. For a coping saw, even when cutting thin metal, you’ll want a fine-toothed blade designed for that purpose.
You can find excellent guides on blade selection for various materials from reputable sources like Popular Mechanics, which often cover the nuances of TPI and blade materials.

Tips for Using Each Saw Effectively
Using the right saw is only half the battle. Proper technique ensures safety, efficiency, and a clean finish.
Hacksaw Tips
- Tension the Blade Correctly: Ensure the blade is taut. A loose blade will wander and break easily.
- Choose the Right Blade: Match the TPI to your material. For metal, use a fine-toothed blade (24-32 TPI). For wood, use a coarser blade (14-18 TPI).
- Grip Firmly: Hold the handle with one hand and the front of the frame with the other for stability.
- Use the Full Blade Length: Don’t just saw with the middle of the blade. Let the entire blade do the work by using long, smooth strokes.
- Let the Saw Do the Work: Apply steady pressure on the push stroke, but don’t force it. Excessive force can break the blade or damage your workpiece.
- Start the Cut Slowly: Especially with metal, start with a few gentle strokes to create a small groove before applying more pressure.
- Secure Your Workpiece: Use a vise or clamps to hold your material firmly in place.
Coping Saw Tips
- Tension the Blade Appropriately: The blade should be tight enough to cut cleanly but not so tight that it snaps. You’ll learn the feel for this with practice.
- Orient the Blade: For cutting curves, you can often rotate the blade within the frame (if your frame allows) so the teeth face away from you, making it easier to see your cut line.
- Support the Workpiece: Use clamps to keep your material stable, especially when cutting intricate shapes.
- Saw on the Pull Stroke: For most coping saw blades, the cutting action is on the pull stroke. This allows you to see your cut line better and control the blade.
- Gentle Pressure: Let the fine teeth do the work. Apply light, steady pressure.
- Follow Your Line: Guide the saw smoothly along your marked line. For tight curves, you might need to make small, rocking motions.
- Relieve Blade Strain: When making very tight turns, you might need to slightly lift the frame or make small adjustments to prevent the blade from binding or breaking.

Frequently Asked Questions (FAQ)
Can I use a hacksaw to cut wood?
Yes, you can, but it’s not ideal. If you need to cut wood with a hacksaw, use a blade with a lower TPI (around 14-18 TPI). A standard metal-cutting hacksaw blade (24-32 TPI) will be very slow and may clog easily when cutting wood.
Can I use a coping saw to cut metal?
A coping saw can cut very thin metals, like sheet metal or thin wire, if you use a blade specifically designed for metal (finer teeth). However, it’s not suitable for thicker metal stock or for making long, straight cuts through metal. A hacksaw is far more appropriate for most metal cutting tasks.
Which saw is better for making curved cuts?
A coping saw is significantly better for making curved cuts. Its thin, flexible blade can easily navigate tight turns and intricate patterns, which is impossible with the rigid blade of a hacksaw.
How do I prevent a hacksaw blade from breaking?
Ensure the blade is properly tensioned in the frame. Use steady, even pressure on the push stroke, and avoid forcing the saw. Also, make sure you’re using the correct TPI blade for the material you’re cutting.
How do I prevent a coping saw blade from breaking?
The most common reasons for breaking coping saw blades are improper tensioning (too tight or too loose) and forcing the saw through the material, especially on tight curves. Let the fine teeth do the work, and support your workpiece well.
What’s the difference in the teeth of the blades?
Hacksaw blades generally have coarser, more robust teeth designed for efficient material removal from harder substances. Coping saw blades are much finer and more delicate, allowing them to cut intricate patterns without snagging or breaking.
Can I replace a hacksaw blade with a coping saw blade, or vice versa?
No, you cannot interchange blades between a hacksaw and a coping saw. They are designed for different frame types, blade lengths, and tensioning mechanisms.
Conclusion: Your Cutting Confidence Starts Here
So there you have it! While both are essential hand tools, the hacksaw and the coping saw are designed for very different jobs.
