Hey there! I'm a supplier of Snap Off Blades 18mm, and I've had my fair share of customers asking me how to avoid dulling these blades quickly. It's a common issue, and I'm here to share some tips and tricks that can help you get the most out of your 18mm snap off blades.
First off, let's talk about what causes these blades to dull in the first place. The main culprit is usually the material you're cutting. If you're using your 18mm snap off blades to cut through tough materials like metal, fiberglass, or thick plastics, the blade is going to wear down much faster than if you're cutting through softer materials like paper or cardboard. Another factor is the pressure you apply while cutting. Applying too much pressure can cause the blade to chip or break, which will also lead to premature dulling.
So, how can you avoid these issues and keep your 18mm snap off blades sharp for longer? Here are some tips:
Choose the Right Blade for the Job
Not all 18mm snap off blades are created equal. Different blades are designed for different types of materials, so it's important to choose the right blade for the job. For example, if you're cutting through metal, you'll want to use a blade that's specifically designed for metal cutting. These blades are usually made from high-speed steel or carbide, which are harder and more durable than regular steel blades. On the other hand, if you're cutting through paper or cardboard, you can use a regular steel blade.
You can find a wide range of Snap Off Blades 18mm on our website, each designed for a specific type of material. Make sure to choose the right blade for the job, and you'll notice a significant difference in how long the blade stays sharp.
Use the Right Cutting Technique
Using the right cutting technique can also help you avoid dulling your 18mm snap off blades quickly. When cutting, make sure to apply even pressure and use a smooth, steady motion. Avoid applying too much pressure or using a sawing motion, as this can cause the blade to chip or break.
It's also important to use the right part of the blade. Most 18mm snap off blades have multiple cutting edges, so make sure to rotate the blade regularly to use all of the edges. This will help distribute the wear evenly across the blade and extend its lifespan.
Keep the Blade Clean
Keeping your 18mm snap off blades clean is another important step in avoiding premature dulling. After each use, make sure to wipe the blade clean with a dry cloth to remove any debris or residue. If the blade is particularly dirty, you can use a mild detergent and water to clean it, but make sure to dry it thoroughly before using it again.
It's also a good idea to lubricate the blade regularly. You can use a light oil or lubricant to keep the blade moving smoothly and prevent it from rusting. Just make sure to use a lubricant that's compatible with the blade material.
Store the Blade Properly
Storing your 18mm snap off blades properly is also important in keeping them sharp. When not in use, make sure to store the blades in a dry, cool place. Avoid storing them in a damp or humid environment, as this can cause the blade to rust.
You can also use a blade storage case to protect the blades from damage. These cases are usually made from plastic or metal and have compartments to hold the blades securely. This will help prevent the blades from getting scratched or bent, which can also lead to premature dulling.
Replace the Blade When Necessary
Even if you follow all of these tips, your 18mm snap off blades will eventually wear down and need to be replaced. It's important to replace the blade as soon as you notice it starting to dull, as using a dull blade can be dangerous and can also cause damage to the material you're cutting.
You can find a wide range of Replacement Snap Off Cutter Blades on our website. Make sure to choose the right replacement blade for your knife, and you'll be back to cutting like a pro in no time.
Consider Using Black Snap Off Blades
If you're looking for a blade that's even more durable and long-lasting, you might want to consider using Black Snap Off Blades for Utility Knife. These blades are coated with a black oxide finish, which makes them more resistant to corrosion and wear. They also have a sharper cutting edge, which means they'll stay sharp for longer.


Black snap off blades are a great choice for anyone who needs to cut through tough materials on a regular basis. They're more expensive than regular steel blades, but they're definitely worth the investment if you want a blade that will last.
In conclusion, avoiding dulling your 18mm snap off blades quickly is all about choosing the right blade for the job, using the right cutting technique, keeping the blade clean, storing it properly, and replacing it when necessary. By following these tips, you can extend the lifespan of your blades and save money in the long run.
