6 Best Keyhole Saws for Woodworking
A keyhole saw is essential for intricate, irregular cuts. Discover the top 6 models that professional woodworkers swear by for precision and control.
Sometimes you need to cut a hole right in the middle of a board, far from any edge. A circular saw can’t do it, and a handsaw is useless until you have a starting point. This is where a keyhole saw, also known as a jab saw, proves its worth, turning an impossible cut into a simple task.

Why Every Woodworker Needs a Keyhole Saw
A keyhole saw is a tool of surgical precision, not brute force. You don’t grab it to break down a sheet of plywood; you grab it to cut a small, precise opening for a pipe in a shed wall or a vent in a chicken coop roof. Its narrow, pointed blade allows you to start a cut anywhere on a surface by simply "jabbing" it through.
Think of it as the key that unlocks interior cuts. A jigsaw needs a pilot hole drilled first, which is an extra step. A larger handsaw is too wide and clumsy for tight curves. The keyhole saw bridges that gap perfectly, giving you control for cutting circles, squares, or any other odd shape your project demands.
Its utility extends beyond wood, too. Most keyhole saws will chew through drywall, PVC, and plastic with ease. For anyone managing a small property, a tool that handles multiple materials is invaluable. It solves problems that other, more powerful saws simply can’t touch.
DeWalt DWHT20540: A Versatile Workshop Staple
The DeWalt jab saw is the ultimate pragmatist’s tool. Its standout feature isn’t a fancy handle or a special tooth design, but its clever use of a standard tool-less blade clamp. This allows it to accept any standard reciprocating saw blade.
This interchangeability is a game-changer. Snap your wood blade? No problem, just grab a new Sawzall blade. Need to cut a piece of metal flashing or a PVC pipe? Swap in the appropriate blade in seconds. This feature alone can save you a trip to town and keep a project moving forward.
While the handle is sturdy and functional, it’s built more for durability than for all-day comfort. This is a tool designed to be tossed in a truck toolbox and relied upon to work every time. It’s a versatile, no-nonsense problem-solver that leverages the blades you likely already own.
Milwaukee 48-22-0304: Rasping Edge for Smoothness
Milwaukee’s approach to the jab saw shows a deep understanding of the actual work involved. After you plunge-cut a hole in drywall or a soft wood like pine, the edge is often fuzzy and uneven. This is where the Milwaukee saw shines with its integrated rasp.
The top edge of the blade features a series of rasping holes. After making your cut, you can use the blade itself to quickly smooth and flatten the edges of the hole. This eliminates the need to grab a separate file or sandpaper, saving a surprising amount of time and frustration. It’s a small detail that makes a huge difference in workflow.
The blade itself is typically thicker and stiffer than many competitors, which provides excellent stability during a plunge cut. This rigidity prevents the blade from buckling or wandering, giving you more confidence and a more accurate starting point for your cut.
Klein Tools 31737: The Best Folding Jab Saw
This durable folding jab saw cuts quickly in both directions with its triple-ground teeth. The lockback mechanism secures the carbon steel blade at 125° and 180°, while the comfortable grip and tether hole add convenience.
Safety and portability are the driving forces behind the Klein folding jab saw. A fixed-blade saw with a sharp, pointed tip is a menace in a crowded tool bag, ready to poke holes in the bag or your hand. Klein, with its deep roots in making tools for tradespeople on the move, solves this problem elegantly.
The blade folds securely into the handle, much like a pocketknife. A robust locking mechanism keeps it firmly in place when open and safely tucked away when closed. This makes it the ideal choice for anyone who carries their tools from one job to the next, whether it’s from the workshop to the barn or out to a fence line.
While designed with electricians cutting drywall in mind, its precision and safety features are a boon for any woodworker. The triple-ground teeth cut aggressively on both push and pull strokes, making quick work of wood panels and other materials. It’s a specialized design that proves incredibly useful for general work.
Stanley 20-556 FatMax: Ergonomic Comfort Grip
If you anticipate using a keyhole saw for more than a few minutes at a time, the Stanley FatMax should be at the top of your list. Its defining feature is its oversized, rubber-molded handle. This isn’t just for looks; it’s about reducing fatigue and increasing control.
A comfortable grip allows you to apply firm, consistent pressure without your hand cramping. When you’re sawing through thick subflooring or trying to make a careful cut overhead, that comfort translates directly into a cleaner, more accurate result. The anti-slip texture ensures a secure hold even with dusty or sweaty hands.
The blade is sharp and durable, with an aggressive tooth pattern that removes material quickly. But the real reason woodworkers favor this model is the handle. Stanley recognized that for a hand tool, the interface between you and the steel is just as important as the steel itself.
LENOX Tools 20997-TFHS6: Superior Blade Durability
LENOX built its reputation on one thing: making exceptionally tough, long-lasting blades. Their keyhole saws are a direct reflection of that legacy. If you’re tired of blades that dull quickly or snap under pressure, this is the brand to look at.
They often utilize bi-metal construction, which bonds a flexible spring-steel back to a high-hardness cutting edge. This combination delivers the best of both worlds. The blade can bend and flex in a tight spot without shattering, while the hardened teeth hold their sharpness through countless cuts in tough material.
This durability means you get a more consistent, predictable cut for the life of the tool. A sharp saw is a safe and efficient saw. Investing in a LENOX often means buying one saw that will outlast several cheaper alternatives, making it a smart choice for anyone who values performance and long-term value.
Bahco 319 Professional: Classic Swedish Steel
For those who appreciate classic, high-quality tools without unnecessary frills, the Bahco 319 is a benchmark. Bahco has been making saws for over a century, and their expertise is evident in the simple, effective design of this tool. The quality starts and ends with the blade.
Made from high-quality Swedish steel, the blade is known for its exceptional sharpness and edge retention. The tooth geometry is often optimized for a fast, clean cut, allowing the saw to power through wood with surprising speed. It’s a pure cutting instrument designed to perform its one job flawlessly.
The handle is a simple, two-component design that provides a solid grip without being overly bulky. There are no folding mechanisms or rasping edges here. The Bahco saw is a testament to the idea that when you perfect the fundamentals—excellent steel and a well-designed cutting edge—you don’t need anything else.
Choosing Your Saw: Blade, Handle, and Features
There is no single "best" keyhole saw for everyone. The right choice depends entirely on how you plan to use it. Your decision ultimately comes down to balancing three key elements: the blade’s performance, the handle’s comfort, and any special features that suit your workflow.
Start by thinking about the job at hand. A few key questions can guide your decision:
- Blade: Will you be cutting mostly soft pine and drywall, or dense hardwoods? Look for bi-metal construction for durability and check the Teeth Per Inch (TPI)—a lower TPI means a faster, rougher cut, while a higher TPI is slower but smoother.
- Handle: Is this for a quick, one-off cut or for a project requiring hours of sawing? An ergonomic handle like the Stanley FatMax will save your hands on larger jobs.
- Features: Do you need maximum portability and safety? The Klein folding saw is the clear winner. Do you value versatility above all else? The DeWalt’s ability to use reciprocating saw blades is unmatched.
Don’t get caught up in finding the one perfect saw. Instead, match the tool to your primary need. If your saw lives in a toolbox that gets bounced around, a folding model is a wise investment. If it hangs on a workshop wall, a fixed blade with a comfortable grip might serve you better. The best tool is the one that makes your specific work easier.
A keyhole saw isn’t the most glamorous tool on the wall, but its ability to make difficult cuts simple makes it one of the most valuable. By choosing one that fits your hands and your work, you’re not just buying a saw; you’re buying a solution to a whole class of woodworking problems.
