1. Types of Jigsaws
Various jigsaw models depend on multiple uses. Understanding the differences between gas, corded, and cordless jigsaws will guide you in the correct blade change processes and help you select the most suitable jigsaw for your project.
Gas-Powered Jigsaws
Description
Gas jigsaws are typically used in industrial or construction settings with limited or no access to electricity. A combustion engine powers these devices, making them highly portable and raw-powered. They are perfect for use in outdoor or remote work sites, but require more maintenance compared to electric ones.
Use Cases:
Site heavy work
- Long-distance construction Works
- Framing and woodwork outdoors
Their power level will enable users to penetrate solid materials, although this may result in louder and heavier devices. Blade replacement is different due to its combustion nature.
Corded Jigsaws
Description
The corded jigsaws are electrically powered jigsaws and can be directly plugged into a wall socket. They deliver uninterrupted power, making them very useful for extended periods of work without the need for recharging.
Use Cases:
- Workshop projects
- Furniture making
- Home renovations
Professionals and hobbyists alike love using these jigsaws because it is very reliable. They are generally lighter than gas-driven counterparts, and many models feature tool-free blade-changing systems, depending on the specific model and brand.
Cordless Jigsaws
Description
Cordless jigsaws operate on rechargeable batteries, and they provide optimum flexibility of motion. New cordless jigsaws, such as those manufactured by ONEVAN, have brushless motors that run more efficiently and longer, according to the manufacturers.
Use Cases:
- Mobile jobs
- Home fixes in a hurry
- Furniture assembly IKEA
Now, you must be clear, what is a jigsaw blade? DIYers particularly appreciate using cordless models due to their lightweight and portability. Mostly, they will also have user-friendly, quick-change blade mechanisms that are tool-free.
2. How to Change a Jigsaw Blade
The correct way to change a jigsaw blade implies preparation, safety, and caution. The general idea is as follows: the old blade is removed, and a new one gets put in, yet the procedure varies depending on the jigsaw. Keep reading to learn how to change the jigsaw blade.

3. How to Change a Jigsaw Blade
Step-by-Step Guide to Changing a Gas-Powered Jigsaw Blade
Compared to gas-powered jigsaws that are engine-driven, they are more demanding in maintenance.
Step 1: Safety Precautions
Find the spark plug and lead wire, and remove them to prevent accidental starting of the jigsaw while changing the blade.
Step 2: Loosen the Clamp
You may need a screwdriver to loosen screws and attach the clamps, depending on your jigsaw. There are models with a lever-type clamp.
Step 3: Remove the Old Blade
Take a firm hold of the blunt end of the old blade and remove it from the clamp. Dispose of it properly, especially if it is broken or bent.
Step 4: Insert the New Blade
Insert the new blade so that the teeth are facing downward and outward. Force it in place until it won't go any farther or you hear a click.
Step 5: Reassemble and Confirm Lock
Put the spark plug lead back in after making sure that the blade is locked.
Step 6: Cleaner After Blade Replacement
Areas to be cleaned:
- Blade clamp
- Exhaust port
- Spark addition space
- Engine housing
Cleaning Method:
Use a dry brush to remove dust and debris from the jigsaw's components.. On hard stains, apply a cloth that has a mild solvent. With the above step-by-step method, you can easily understand how to remove the jigsaw blade.

Step 3: Take Out the Old Blade
Pull out the blade by lifting the release lever.
Step 4: Insert the New Blade
Fit the new blade into the clamp with the teeth pointing forward, towards the front of the jigsaw. Free the lever to lock it.
Step 5: Lock the blade
Pull out the blade slightly to ensure that it is well fastened.
Step 6: Washing of Cordless Jigsaw
Places to clean:
- Battery contacts
- Blade holder
- Air vents

4. Common Mistakes When Changing Jigsaw Blades
Indicators of common mistakes to prevent optimal tool performance:
Failure to adhere to Safety Measures
Failure to unplug the tool or remove the battery may lead to accidental starts, which can be dangerous..
Applying Wrong Blades
Different jigsaws require specific types of shanks, and using an incorrect blade can lead to poor performance and potential damage. Most modern tools use T-shank blades, and all ONEVAN models as well.
Badly secured blades
This may happen when the blade is not well held, causing an unsteady movement of the blade, bad cuts, and even breaking.
Neglecting Cleaning
Blade seating may be affected, as well as the life of the motor, due to the buildup of dust and debris in the clamp or vents.
Implementing the Change too fast
Spend time plugging and fixing the blade. Hurrying may lead to being out of focus or damaging tools.
5. How to Pick a Jigsaw Blade
Selecting an appropriate blade is similar to learning how to replace it. The quality of cutting, its speed, and safety depend on blade selection.
Blade Materials
- HCS (High-Carbon Steel): Ideal for cutting softwood and plastic; not recommended for harder materials.
- High-speed steel (HSS): Harder materials such as metal
- Bi-Metal: Offers flexibility and durability, making it suitable for cutting both wood and metal without breaking easily.
- Carbide Grit: Ceramics, glass, and masonry
Shank Types
T-Shank: Accepted as a standard of the jigsaw of today; changed more easily
U-Shank: Antique model; needs a tool to replace
TPI (Teeth per inch)
- 6-10 TPI: Suitable for rough cutting
- 10–20 TPI: Suitable for medium finish cuts
- Plastic or Metal 20+ TPI: Thin metal cuts
Use the different blade types to match the material that gives the most effective results, together with the jigsaw model.
