12″ 5TPI High Carbon Steel Blades
Strengths
- 12-inch deep cutting reach
- Heat-treated HCS steel
- Good chip removal
Trade-offs
- Still wears in gritty soil
- Not carbide-tipped
- Slight flex in hard roots
The 12-inch length here is the real story, offering deeper reach than 9-inch blades without the flex issues of 15-inch models. That makes it a smart middle ground for cutting through deep-set roots, especially in landscaping or trenching jobs. The 5TPI dual-angle tooth design cuts fast, and the HRC50–54 heat-treated HCS steel gives it better durability than basic pruning blades.
Owners using this for root excavation appreciate the blend of depth and control. It’s not as long-lasting as carbide in dirty soil, but for moderate jobs where you need more reach than a 9-incher provides, this is one of the few well-built options. The included storage case is a nice touch, though the blade material still limits its lifespan in abrasive conditions.

15″ Japanese Teeth Arc Edge Blades
Strengths
- Long 15-inch reach
- 6TPI fleam-ground teeth
- Universal shank (most brands)
Trade-offs
- Not for Ryobi saws
- Flex risk in hard-packed soil
- Slower in dirty roots
At 15 inches long, these blades are built for reach, ideal when you’re dealing with thick roots buried deep in soil and need maximum stroke depth. The 6TPI Japanese tooth design with fleam grinding stands out for clean, fast wood removal, and owners consistently report less binding when cutting through tangled or fibrous roots. On paper, the chromium-vanadium steel offers solid durability, though it’s not quite in the same league as carbide when grinding through dirt-encrusted material.
Still, their length gives them a niche advantage over shorter blades, few competitors even offer 15-inch options. That said, the extra length can flex more in dense material if your saw lacks sufficient control, and the incompatibility with Ryobi saws is a real limitation for some users.

Goshine 9″ Fleam Ground Teeth Blades
Strengths
- Smooth, controlled cuts
- Dual-angle tooth design
- 0.05-inch thick for stability
Trade-offs
- Still HCS, not carbide
- Not for gritty conditions
- No storage case included
Goshine’s 5TPI blades stand out for delivering notably smoother cuts in green wood and softer roots, thanks to their dual-angle tooth drive and double-sharpened teeth. On paper, the 0.05-inch thickness provides extra stiffness, helpful when pushing through fibrous material without wandering. Owners report less vibration and cleaner results compared to standard HCS blades, making these a strong contender if precision matters.
That said, they’re still high-carbon steel, so they won’t match carbide in abrasive, dirt-heavy root cutting. Where they shine is in clean, wet wood, ideal for pruning near lawns or gardens where roots aren’t heavily compacted with soil. Compared to the B07KXCP2Y1 pack, these feel more refined, though at a slightly higher cost.

Our Testing Process
Rather than a hands-on lab test, my research focused on comparing published specifications and features of various sawzall blades designed for wood and root cutting. I weighed owner reviews from multiple retailers and reputable tool sites, looking for patterns in performance and durability. Ultimately, I ranked blades based on their suitability for the specific task of cutting roots, considering material, tooth design, and shank compatibility.
For this category, tooth material and teeth per inch (TPI) were the most heavily weighted factors. Carbide teeth offer significantly longer life when encountering abrasive materials like dirt and roots, and a lower TPI is generally better for thicker, tougher material. Blade thickness also mattered – thicker blades resist bending during aggressive cuts. Understanding teeth per inch guide is critical when choosing the right blade.
Specifications reliably indicate blade dimensions, shank type (ensuring universal compatibility), and material composition. However, I relied on owner feedback to assess real-world durability and cutting speed. Reports on how well a blade holds an edge and whether it bends or breaks during use were particularly valuable, as these aren’t always apparent from manufacturer claims. Owners also provided insights into suitability for different root sizes, helping to refine the rankings.
How To Pick The Right sawzall blade for cutting roots in dirts
Choosing the right sawzall blade for root cutting can make a huge difference in how quickly – and how easily – you finish the job.
A quality sawzall blade for this application prioritizes tooth geometry suited for dense, abrasive materials. Look for blades with carbide teeth for extended life, a TPI (teeth per inch) appropriate for the root diameter, and a shank compatible with your saw. Blade thickness and material also impact performance and durability.
Tooth Material: Carbide vs. Bi-Metal
The material a blade is made from is arguably the biggest factor in its performance and longevity when tackling roots. While bi-metal blades are versatile, for serious root cutting, carbide tipped blades are the way to go. They hold an edge significantly longer – up to 50 times longer, according to some manufacturers – because carbide is much harder than the high-speed steel used in bi-metal blades. This is vital for abrasive materials like roots which will quickly dull a standard blade. You’ll pay more upfront, but the reduced downtime from frequent blade changes will save you time and money in the long run.
Teeth Per Inch (TPI) and Root Diameter
The TPI determines how aggressively a blade cuts. Lower TPI blades (like 3 or 5) remove more material per stroke, making them faster for thicker roots and branches. Higher TPI blades (6 or more) offer finer cuts, better suited for smaller diameter roots or cleaner finishes. However, packing too many teeth into a root can lead to clogging and increased friction.
Here’s a quick guide:
- For roots under 2 inches: 5-6 TPI.
- For roots 2-6 inches: 3-5 TPI.
- For roots over 6 inches: A coarser 3 TPI blade, and be prepared to potentially replace Sawzall blade multiple times during a large job.
Blade Length and Shank Type
Blade length needs to match the task. A 9-inch blade is good for general pruning and smaller roots, but you’ll need a 12-inch or even 15-inch blade to reach deeper or thicker roots. Beyond length, shank compatibility is crucial. The vast majority of sawzalls use a 1/2-inch universal shank, but it’s always best to double-check your saw’s manual. Ensuring a snug fit prevents slippage and ensures efficient power transfer. If you are looking for specialized options, explore reciprocating saw blades for trees or even root-cutting sawzall blades designed specifically for these materials.
Don’t skimp on blade quality; a dull blade requires more force, is more dangerous, and ultimately takes longer to complete the task.

Frequently Asked Questions
What blade length is best for most root cutting jobs?
A 9-inch blade handles smaller roots well, but for deeper cuts or larger diameter roots, a 12- or 15-inch blade is typically needed. Remember to consider the accessibility of the root when selecting a length.
Can I use a standard wood-cutting blade to cut roots?
While possible, it’s not ideal. Standard blades lack the durable tooth material needed for abrasive roots and will dull quickly, while also increasing the risk of breakage. Consider wood-cutting sawzall blades for other tasks, but use carbide for roots.
What TPI should I use if I encounter roots of varying sizes?
A 3-5 TPI blade provides a good balance for different root diameters. If you regularly face a wide range of sizes, having both a 3 TPI and a 5 TPI blade on hand will optimize cutting speed and efficiency.
Are carbide blades really worth the extra cost?
Yes, they are. Carbide blades last significantly longer, sometimes 50 times longer, when cutting through abrasive materials like roots. This reduces downtime and the overall cost of blade replacement for larger projects.
What should I do if my sawzall blade keeps bending during root cutting?
Blade bending indicates you may be using a blade that’s too thin or made of an insufficient material. Switch to a thicker gauge blade with carbide teeth designed for tougher materials, and ensure you aren’t applying excessive pressure.
The Bottom Line
Choosing a sawzall blade for root cutting often comes down to balancing upfront cost with long-term efficiency. While bi-metal blades have their place, for consistent performance against abrasive roots, the 9″ 3TPI Carbide Tipped Sawzall Blades stand out as the strongest overall choice. They offer a good balance of carbide durability, aggressive cutting action, and a reasonable price point for a multi-pack, minimizing downtime during larger projects.
If you’re on a tighter budget, the Goshine 9″ Fleam Ground Teeth Blades are a solid starting point, offering decent cutting ability for smaller roots. For those needing greater versatility for pruning and occasional root cutting, the 15″ Japanese Teeth Arc Edge Blades provide extended reach and a finer tooth pattern. Remember to review reciprocating saw techniques before starting your project.
Ultimately, the best blade isn’t about a single specification; it’s about matching the tool to the task and prioritizing quality. Don’t underestimate the value of carbide teeth for longevity, and always ensure a secure fit with the correct shank type. Mastering cutting roots with reciprocating saw and prioritizing safety will deliver the best results, no matter which blade you select.
