To cut nails and screws with a multi tool, use a metal-rated blade, not a standard wood blade. The best choice is usually a bi-metal blade for light nails and soft metal, or a carbide blade for tougher screws, bolts, and harder metal.
If you are choosing a multi tool blade for cutting nails, check three things first: blade material, tool fit, and the type of metal you need to cut. This helps you avoid broken teeth, overheating, and slow cuts.
A multi tool is useful because it can cut close to walls, floors, trim, and tight corners. That makes it helpful for renovation work, flooring, skirting boards, door frames, and old timber with hidden fixings.
This guide explains which blade to use, how to cut nails and screws safely, and what mistakes to avoid before buying blades.

What Is a Multi Tool Blade for Cutting Nails?
A multi tool blade for cutting nails is an oscillating blade made to cut metal fasteners. These include nails, screws, pins, staples, and small bolts.
These blades are usually made from bi-metal or carbide. A standard wood blade is not designed for metal. StarlockBlade.co.uk’s wood blade product page notes that wood blades are mainly for wood and soft materials, and that metal cutting should be done with a dedicated bi-metal or metal-rated blade.

Key Differences Explained
Fit and Mounting
The blade must fit your multi tool. Some tools use Starlock. Others use universal or brand-specific fittings.
A secure fit matters when cutting metal. If the blade wobbles, it can overheat, wear faster, or leave a rough cut.
If you are not sure which mount you have, read our guide on Starlock vs Universal Multi-Tool Blades.
Compatibility

Compatibility means the blade locks onto your tool correctly.
Do not buy a blade just because it says “metal cutting.” Also check whether it fits your tool. Look for words such as:
-
Starlock
-
Universal fit
-
OIS-compatible
-
Adapter required
-
Quick-release compatible

Cutting Performance
Bi-metal blades work well for many common fasteners. They are useful for nail-embedded wood, trim removal, and light renovation cuts.
Carbide blades are better when the metal is harder. In StarlockBlade.co.uk’s cutting guide, nail-embedded wood is matched with bi-metal blades, while screws and bolts are matched with carbide blades and light pressure.
Vibration and Control
Metal cutting creates more vibration than cutting clean wood. A loose blade makes this worse.
Hold the tool with both hands when possible. Keep the blade steady. Let the oscillating motion do the cutting.
If the tool starts to bounce, reduce pressure and check the blade.
Durability
Cutting nails and screws is hard on blades. Heat is the main problem.
A dull blade creates more friction. More friction creates more heat. Heat can damage the blade teeth and slow the cut.
Take short breaks during metal cuts. StarlockBlade.co.uk’s material guide recommends low-to-medium speed and regular pauses when cutting metal.
Price and Value
Bi-metal blades are often a good value for general DIY and renovation work.
Carbide blades may cost more, but they are useful when cutting harder screws or repeated metal fasteners. The best value is not always the cheapest blade. It is the blade that fits your tool and matches the material.
How to Cut Nails and Screws with a Multi Tool

Follow these steps for cleaner, safer cuts.
1. Check the Fastener
Look at what you need to cut. Is it a small nail, a screw head, a staple, or a bolt?
For small nails and pins, use bi-metal. For tougher screws or bolts, use carbide.
2. Choose the Right Blade
Do not use a wood-only blade. It can lose teeth quickly if it hits metal.
Choose a blade marked for:
-
Metal
-
Bi-metal
-
Carbide
-
Wood with nails
-
Screws or bolts
3. Check Tool Compatibility
Fit the blade onto your multi tool before starting. Make sure it locks in firmly.
Unplug the tool or remove the battery before changing blades.
4. Set a Lower Speed
Metal cutting works best at a lower speed than wood cutting. Too much speed creates heat.
Start low. Increase only if the cut stays smooth.
5. Start the Cut Slowly
Place the blade against the nail or screw. Start with light pressure.
Do not force the blade. Let the teeth or carbide edge grind through the metal.
6. Pause to Control Heat
Stop often during longer cuts. Let the blade cool naturally.
Do not touch the blade right after cutting. It may be hot.
7. Finish and Check the Area
Once the fastener is cut, check for sharp edges. Remove loose metal pieces before continuing the job.
Wear eye protection. Small metal pieces can fly during cutting.
Which Blade Should You Choose?
Beginners and Casual DIY Users
Choose a bi-metal blade first. It is the most useful option for light nails, old trim, staples, and nail-embedded wood.
If you also need to make clean timber cuts, use dedicated multi tool wood blades for the wood-only parts. Switch to a metal-rated blade before cutting nails or screws.
Budget-Focused Buyers
Do not choose price over fit. A cheap blade that does not fit well can vibrate, slip, or wear out fast.
Start with one bi-metal blade that fits your tool. Add carbide later if you cut tougher screws often.
Professionals and Frequent Users
Professionals should keep both bi-metal and carbide blades on hand.
Bi-metal is useful for general site work. Carbide is better for demanding cuts, hard fasteners, and repeated metal work.
Renovation and Mixed-Material Jobs
Use bi-metal or carbide when working on old timber, skirting, flooring, or door frames.
Old materials often hide nails, screws, pins, and staples. A wood-only blade may be fine at first, then fail as soon as it hits metal.
Users Who Need the Best Fit and Control
Choose blades that match your tool mount. A firm fit gives better control and less vibration.
This matters when cutting close to finished floors, painted trim, or visible wood.

FAQ
Is a bi-metal blade better than a carbide blade for nails?
A bi-metal blade is usually better for light nails, pins, staples, and nail-embedded wood. It is flexible and good for mixed renovation work. A carbide blade is better for harder screws, bolts, and tougher metal. Choose based on the fastener, not just the price.
Does a multi tool blade for cutting nails fit all tools?
No, a multi tool blade for cutting nails does not fit all tools. You still need to check the mount. Some blades use Starlock fittings, while others use universal fittings. Always check your tool model and blade listing before buying.
Can I use a wood blade to cut nails?
No, you should not use a standard wood blade to cut nails. Wood blades are made for timber, MDF, plywood, and similar materials. If they hit metal, the teeth can dull or break quickly. Use a bi-metal or carbide blade for nails.
Can I cut screws with a multi tool?
Yes, you can cut screws with a multi tool if you use the right blade. For small or soft screws, a bi-metal blade may work. For harder screws or bolts, use a carbide blade. Cut slowly, use light pressure, and pause often to control heat.
How long do blades last when cutting nails?
Blade life depends on the metal, blade type, speed, and pressure. Light nails may only cause minor wear. Hardened screws can wear blades much faster. If the blade cuts slowly, turns blue, smokes, or needs extra pressure, replace it.
What should beginners buy first?
Beginners should buy a metal-rated bi-metal blade that fits their tool. This covers many common jobs, including nails, staples, and nail-embedded wood. If you expect harder screws or bolts, add a carbide blade. For clean wood cuts, use a separate wood blade.
Are Starlock blades worth it for cutting nails and screws?
Starlock blades are worth considering if your tool supports Starlock. A secure mount can help reduce vibration and improve control during metal cuts. The blade material still matters most. Choose bi-metal or carbide for nails and screws, not a standard wood-only blade.
Conclusion
Choosing the right multi tool blade for cutting nails is simple once you know the material. Use bi-metal for light nails, staples, and nail-embedded wood. Use carbide for tougher screws, bolts, and harder metal.
Do not use a wood-only blade on nails or screws. It can dull quickly and make the cut harder. Keep wood blades for clean timber cuts, and switch to a metal-rated blade when fasteners are involved.
