Can I use a regular concrete diamond blade on asphalt?

You can, but it will wear out much faster. Concrete blades use a soft bond that wears quickly in abrasive, soft material like asphalt. You'll burn through blades at 2-3 times the rate. Use a hard-bond asphalt blade instead — it's cheaper in the long run.

What RPM should I run for asphalt cutting?

Follow your saw manufacturer's recommended RPM. For most 14-inch high-speed saws, that's around 4,400 RPM. Never exceed the blade's rated speed — it's printed on the blade or packaging. Running over-speed creates a safety hazard and voids the warranty.

How deep can a 14-inch blade cut in asphalt?

A 14-inch blade on a standard high-speed saw cuts approximately 4.5 to 5 inches deep. That's enough for most asphalt pavement, which is typically 2-4 inches thick over a base layer. For thicker commercial asphalt, you may need a walk-behind saw with a larger blade.

Best Diamond Blades for Cutting Asphalt (2026)

Cutting asphalt is nothing like cutting cured concrete. Asphalt is softer, stickier, and full of aggregate that can clog the wrong blade in seconds. If you grab a standard concrete blade and try to cut an asphalt driveway, you’ll burn through it fast — and the cuts will be ugly.

The fix is simple: use a blade built specifically for asphalt. These best diamond blades for asphalt use a harder bond that resists premature wear in soft material, and wider gullets that clear the gummy debris. Below are the blades that get it right.

Why Asphalt Needs a Different Diamond Blade

Diamond blade performance depends on the match between blade bond and material hardness. In cured concrete (hard material), you use a soft bond so fresh diamonds are exposed as the bond wears. In asphalt (soft material), the opposite applies — you need a hard bond so the blade doesn’t wear out before the diamonds do their work.

Asphalt also generates a lot of sticky debris — the tar binder softens during cutting and can gum up blade segments. Good asphalt diamond blades have wider gullets (the gaps between segments) to flush this material out instead of clogging.

Best Diamond Blades For Asphalt: Our Top Picks

1. Virginia Abrasives 14″ BD Asphalt / Green Concrete Blade — Best Overall

Check price on Amazon

The Virginia Abrasives BD Asphalt / Green Concrete blade is purpose-built for exactly these materials. It uses a hard bond formulation that holds up in soft, abrasive material without wearing prematurely. The segment design clears debris effectively, even in the thick, gummy slurry that asphalt cutting creates.

What we like most: this blade pulls double duty. It handles both asphalt and green (uncured) concrete equally well. If your crew does road work, parking lot repairs, and early-entry saw cutting on fresh pours, one blade covers both applications. That simplifies your inventory and means fewer stops to swap blades.

Best for: Asphalt patching, road cuts, parking lot work, green concrete saw cutting, and any application in soft or abrasive material.

Specs:

Diameter: 14 inches
Arbor: 1 inch (includes 20mm bushing)
Bond type: Hard (designed for soft/abrasive materials)
Application: Asphalt, green concrete, soft aggregate
Made in the USA

Pros: Hard bond lasts in soft material. Handles both asphalt and green concrete. Wide gullets clear debris well. US manufacturing consistency.

Cons: Not suitable for cured concrete — the hard bond won’t expose new diamonds fast enough. Limited to soft/abrasive materials.

2. Husqvarna Elite-Cut S45 14″ Asphalt Blade

The Husqvarna S45 is designed specifically for asphalt and abrasive materials. Husqvarna’s brand reputation and dealer network make this a popular choice among contractors who already run Husqvarna saws. The blade performs well in standard asphalt cutting and delivers clean edges on road patches.

In our experience, the S45 matches the VA BD on cut quality but costs more per blade. If you need to buy the best diamond blades for asphalt at a local dealer today and can’t wait for shipping, the Husqvarna availability advantage matters. Otherwise, the VA option provides similar performance at a better price.

Best for: Husqvarna saw owners, contractors who need immediate blade availability through dealer networks.

Pros: Purpose-built for asphalt. Strong dealer network. Consistent performance.

Cons: Premium pricing. No significant performance advantage over the VA BD blade.

3. MK Diamond 159108 MK-303D 14″ Asphalt Blade

The MK-303D has been an industry staple for asphalt cutting. MK Diamond has a long track record in the saw blade business, and this blade reflects that experience. It uses a hard bond with a segment design optimized for abrasive materials.

The MK-303D cuts clean in standard asphalt and holds up reasonably well on long runs. Where it falls behind the VA BD: blade life per dollar. MK blades tend to be priced higher without delivering proportionally more cuts. But the MK name carries weight with some crews, and dealer support is solid.

Best for: MK Diamond saw owners, crews with existing MK blade commitments.

Pros: Proven track record. Established brand. Decent cut quality in asphalt.

Cons: Higher price point than VA without proportional performance gain. Availability can vary by region.

How to Get the Most Life from Your Asphalt Blade

Even with the best diamond blades for asphalt, technique matters. Here’s how to maximize blade life when cutting asphalt.

Use Water Whenever Possible

Asphalt cutting generates heat, and heat is the enemy of blade life. Wet cutting keeps the segments cool and flushes debris from the cut. If your saw has a water attachment, use it — you’ll see significantly longer blade life and cleaner cuts.

Don’t Force the Cut

Let the blade do the work. Pushing too hard into asphalt causes the segments to overheat and can actually slow the cut down. A steady, consistent feed rate produces better results than brute force. If the blade is slowing down, you’re probably pushing too hard or the blade is glazed.

Sharpen a Glazed Blade

If your asphalt blade stops cutting efficiently, the segments may be glazed — the bond has smeared over the diamond crystals. The fix is simple: make a few cuts in abrasive material like a cinder block or sandstone. This wears away the glazed surface and exposes fresh diamonds. It’s a quick trick that can bring a “dead” blade back to life.

Asphalt vs. Green Concrete: Same Blade?

Yes — in most cases, the same hard-bond blade works for both. Asphalt and green concrete are both relatively soft and abrasive. A blade like the VA BD Asphalt / Green Concrete is specifically designed to handle both. This makes it ideal for crews who do early-entry saw cutting on fresh pours and also do road patch or parking lot work.

The exception: once concrete cures past about 48-72 hours, it starts hardening. At that point, you need to switch to a soft-bond blade. Not sure which blade to use? Check out our Best Diamond Blades for Concrete roundup. For more information, see National Asphalt Pavement Association.
