Expert 9″ 8TPI Carbide Sawzall Blades
Strengths
- Carbide-tipped teeth
- TiAlN + ICE coating
- 8TPI aggressive cut
- Long lifespan on hard metals
- Universal fit
Trade-offs
- High price per blade
- Only 3 per pack
- Overkill for soft metals
Carbide-tipped and coated with TiAlN + ICE, these Expert blades are built for the worst metals, stainless, hardened steel, thick bolts. The 8TPI design is aggressive, clearing material fast and resisting clogging. While bi-metal blades dull quickly on stainless, owners report these lasting significantly longer, which justifies the higher cost over time.
The 100x lifespan claim is marketing exaggeration, but real-world feedback suggests they do outlast bi-metal by a wide margin in tough jobs. The downside? Only three blades per pack and a higher upfront cost. But if you’re cutting hardened steel or thick iron pipe regularly, this is the smarter buy. Compared to the HORUSDY, it’s in a different class, not for general use, but for when bi-metal just won’t survive.

Trade-offs
- 6-inch length limits deep cuts
- TPI combo may not excel in very thick steel
This 25-pack gives you serious volume for the money, and the 9% cobalt content in the M42 steel stands out on paper. That extra cobalt should translate to better heat resistance and edge retention when slicing through thick steel pipe or rebar, a claim backed by owners who report fewer dulling cycles compared to standard bi-metal blades. The 14/18 TPI combo makes sense for mixed-metal jobs, tackling both thinner sheet metal and thicker sections without constant blade swaps.
Where it really shines is in durability. The four-level heat treatment process seems to deliver, with multiple reviewers noting these blades resist snapping under aggressive use. For a DIYer running frequent demolition or a pro who hates changing blades every few cuts, this pack offers real value. It’s not the longest blade here, but for medium-thickness metals up to 5/16 inch, it holds its own against pricier names like Milwaukee.

Our Testing Process
Rather than a hands-on lab test, my research focused on a detailed comparison of published specifications and features across numerous reciprocating saw blades marketed for metal cutting. I weighed owner reviews from major retailers alongside expert opinions found in trade publications and tool-focused websites. This allowed me to build a ranking based on real-world user experience and technical capabilities, applying my years of experience with power tools to assess which blades consistently perform well.
For blades designed for steel pipe and rebar, cutting speed and durability are paramount. I gave the most weight to blades featuring high cobalt content in their bi-metal construction, as this directly translates to increased wear resistance when tackling tough materials. Equally important was the tooth pitch; understanding teeth per inch explained is crucial for matching the blade to the material thickness and desired cut quality.
Specifications reliably indicate material composition (bi-metal, carbide, etc.) and physical dimensions like blade thickness and shank type. However, I found owner feedback to be invaluable for gauging real-world durability and how well a blade holds its edge. Reputational factors – brands consistently praised for quality – also played a role, offering a degree of confidence beyond the listed features. Knowing TPI for metal cutting helps interpret those user reports.
What To Look For In reciprocating saw blades for cutting steel pipes and rebars
Selecting the right blade is critical for clean, efficient cuts – especially when working with steel pipe and rebar.
A quality reciprocating saw blade for metal work features a robust bi-metal construction, a tooth pitch (TPI) suited to the material thickness, and a shank designed for universal compatibility. Users should prioritize blades with heat-treated teeth and reinforced bodies to resist wear and breakage during demanding applications. Consider the specific metal being cut and the desired cutting speed when selecting a blade.
Tooth Pitch (TPI) Matters
The number of teeth per inch (TPI) is probably the most misunderstood aspect of blade selection. Lower TPI counts (6-8) are aggressive and excel at quickly cutting through thicker materials, but leave a rougher finish. Higher TPI counts (14-18) produce cleaner cuts in thinner materials, but cut more slowly and are more prone to binding if forced. Don’t assume more teeth are always better. For steel pipe and rebar, a 14 TPI blade is a good starting point, offering a balance between speed and finish. However, thicker rebar often benefits from an 8 TPI blade.
Bi-Metal Construction & Cobalt Content
Bi-metal blades are the standard for metal cutting, combining a high-speed steel tooth edge with a flexible backing steel body. This resists breakage better than all-steel blades. But not all bi-metal is created equal. Look for blades that specifically mention cobalt content in the tooth edge. Cobalt significantly increases wear resistance and allows the blade to maintain its sharpness longer. Blades with 8% or higher cobalt content, like those from Goshine and LOZAGU, are noticeably more durable. If you’re frequently cutting abrasive materials, this is where you’ll see a real return on investment.
Value and Usability: Shank Type & Pack Size
Most reciprocating saws use a standard 1/2-inch shank, and thankfully, nearly all blades on the market adhere to this standard. However, the convenience of a blade doesn’t stop there. Consider the pack size. Buying a single blade is fine for occasional use, but if you’re tackling a large project, a bulk pack like the 25-pack from Goshine can save you money and keep you cutting without interruption. Also, make sure you’re comfortable with the reciprocating saw blade replacement process; a quick change can be a lifesaver on the jobsite.
A dull blade isn’t just inefficient, it’s dangerous. If you find yourself forcing the saw or the blade is heating up excessively, stop and install a fresh blade.

Frequently Asked Questions
What TPI blade is best for very thick rebar?
An 8 TPI blade is generally best for very thick rebar, as the lower tooth count allows for faster material removal and reduces binding compared to higher TPI blades. While a 14 TPI blade is a good all-around choice, extremely dense or large-diameter rebar demands the more aggressive cut of a coarser tooth.
Are carbide reciprocating saw blades really better for steel?
Carbide blades offer exceptional durability when cutting highly abrasive materials, but for straightforward steel pipe and rebar, high-cobalt bi-metal blades typically provide a better balance of speed, cost, and cut quality. You’ll likely only see a benefit from carbide if you’re cutting heavily alloyed or extremely hard steel.
How can I tell if a reciprocating saw blade is worn out?
A dull blade will require excessive force to cut, and the blade itself may become hot during use. If you notice these signs, it’s time to replace the blade; continuing to use a dull blade is inefficient and can be dangerous.
Do I need different blades for different types of steel?
While a high-quality bi-metal blade with appropriate TPI can handle most steel types, harder alloys or those with high tensile strength may benefit from blades with higher cobalt content. For consistently thick metal cutting performance, a blade specifically designed for tougher materials will last longer and perform more reliably.
What’s the advantage of buying reciprocating saw blades in a bulk pack?
Buying blades in a bulk pack, like a 25-pack, significantly reduces the cost per blade and minimizes downtime during large projects. Having multiple blades on hand ensures you always have a sharp blade ready to go, improving efficiency and safety, and ultimately saves you money over time.
The Bottom Line
Choosing a reciprocating saw blade always comes down to balancing how much you want to spend with how much abuse the blade will take. For most homeowners and DIYers facing occasional metal cutting, the Goshine 25-Pack offers a fantastic combination of performance and value.
