Are Spyder Carbide Reciprocating Saw Blades Worth It?
I put carbide reciprocating saw blades to work in wood with nails, metal tubing, and a steel beam. But an impressive cut is only part of the story.
I’m breaking down three Spyder Tarantula blades, the jobs each is designed for, and where carbide might earn its price. This is a hands-on introduction, not a head-to-head comparison or blade-life test.

Are Carbide Reciprocating Saw Blades Worth It? My First Look
I brought a FLEX reciprocating saw, one of each Spyder blade, and some material that needed to become smaller material. The goal was straightforward: show what each blade does, inspect it afterward, and explain the buying decision.
The wood-and-nails cut stood out for its smooth result. After the demonstrations, my inspections showed the cutting teeth intact. Those are useful first impressions, but they do not establish how long the blades will last.
I’ve also covered five unusual Spyder reciprocating saw attachments. This time, the focus is the cutting edge, not turning the saw into a scraper or brush.
Carbide Reciprocating Saw Blades vs. Bi-Metal Blades
What changes at the cutting teeth?
According to Spyder’s blade-construction guide, bi-metal combines a high-carbon-steel body with high-speed-steel teeth. These Tarantula models use carbide-tipped teeth. That does not mean the entire blade is solid carbide.
The attraction is useful cutting life. A blade that keeps working effectively can mean fewer replacements and fewer interruptions. That matters when the job keeps handing you demanding material, not just one convenient demonstration piece.
What does “up to 60 times more cuts” mean?
Spyder advertises up to 60 times more cuts than standard bi-metal blades. That is the manufacturer’s claim, not a result established by my demonstrations.
Notice the wording: more cuts, not 60 times faster. In the video, I described the blades as cutting rapidly and expressed my belief about their speed relative to bi-metal. I did not run a matched, timed comparison, so that remains an impression.
Bi-metal still has a place. For occasional work, an appropriate blade you already own may handle the job perfectly well. The carbide upgrade needs to deliver something you actually need.
Which Spyder Carbide Blade: 6 TPI, 10 TPI, or 8 TPI?
TPI means teeth per inch. All three featured blades are nine inches long, but their application markings are different.
| Model | TPI | Application | Marked metal thickness |
|---|---|---|---|
| 200438 | 6 | Wood/nails | Not specified here |
| 200375 | 10 | Medium metal | 1/16–5/16 inch |
| 200372 | 8 | Thick metal | 3/16–9/16 inch |
These are not three levels of the same blade. Start with the material and its thickness, then match the application. A bigger TPI number does not automatically mean a better choice.
The two metal ranges overlap between 3/16 and 5/16 inch. That does not make the blades identical. Some material falls within both markings, leaving cutting performance and useful life as questions for a matched comparison.
Spyder 200438: 6-TPI Carbide Blade for Wood With Nails

The Spyder 200438 wood-and-nails blade was first up. I prepared two-by lumber with 11 framing nails for the demonstration.
Cutting wood is one task. Cutting metal is another. As I explained in the video, a blade intended to handle both needs tooth geometry suited to that mixed-material job.
What I saw after the nail-embedded wood cut
After cutting, I checked the teeth and carbide tips. Everything looked intact, with no visible misalignment. The result also looked smooth through both the lumber and the embedded metal. I specifically pointed out that the cut metal did not look jagged.
That is the application to remember: lumber containing framing nails, like the material encountered during demolition. I was pleased with this demonstration, but an intact blade after the cut is not the same as a completed endurance test.
For smaller openings or a different cutting approach, see my oscillating multi-tool blade selection guide. Match the tool and accessory to the work, rather than expecting one blade to solve everything.

Spyder 200375: 10-TPI Carbide Blade for Medium Metal

Next was the Spyder 200375 medium-metal blade. Its marking specifies material thicknesses from 1/16 to 5/16 inch.
For tubing, wall thickness is different from outside diameter. Check the actual wall and material against the blade’s application guidance. I did not call out the tubing’s wall measurement in this demonstration. Measure your material carefully before choosing a blade.
My metal-tubing demonstration and first impressions
I called attention to electricians and conduit work when introducing this blade. I also mentioned thinner angle iron and similar metal sections as possible applications, provided they match the blade’s rating.
After the tubing demonstration, I inspected the blade and found the teeth intact. I also commented that I could not feel heat coming from the workpiece at that moment.
That was an immediate observation, not a temperature measurement. Do not read it as a guarantee of heat-free cutting or proof that this method is always safer. Treat freshly cut metal and blades cautiously.
My enthusiasm for conduit work is not a blanket recommendation for every conduit. The material and wall thickness still have to suit the blade. The application marking matters more than the trade using it.
For another approach to metalwork, my grinder wheel selection guide separates cutting, grinding, and finishing applications.

Spyder 200372: 8-TPI Thick-Metal Carbide Blade on a Steel Beam

The Spyder 200372 thick-metal blade was the choice for the large steel beam, which I called an H-beam in the video. Its published thickness marking is 3/16 to 9/16 inch.
That range concerns the metal being cut. It does not describe the beam’s overall height. Check individual section thicknesses and material suitability before attempting a comparable cut.
Cutting the upper and lower flanges
Before starting, I made one thing clear: this was not wood. Even with a capable saw and an appropriate blade, the steel-beam cut was going to take time.
The close-ups show the blade working through the beam’s upper and lower flanges. This was the heavier-metal demonstration, not a race against another manufacturer.
Afterward, I checked the blade: every tooth looked intact, and it was ready for another cut. That was the result that mattered to me in this first look: the blade had completed the demonstrated work with its teeth still present.
I am not assigning it a lifetime cut count from that inspection. A longer series of controlled cuts would be needed to investigate wear and replacement intervals.

Using Carbide Reciprocating Saw Blades Safely
My demonstrations are not a substitute for your tool’s instructions. Spyder’s accessory safety guidance directs users to the power-tool manual and warns against forcing the tool.
Secure the workpiece, maintain blade clearance throughout the stroke, and use appropriate eye and hearing protection. Remove the battery before changing or inspecting the blade. Follow your saw’s instructions for metal-cutting speed, orbital settings, and lubrication.
For example, FLEX’s FX2271 manual prohibits orbital action when cutting metal and recommends cutting oil for steel and soft metals. Check the instructions for your exact saw; those details are manufacturer guidance, not a record of every setting used during my demonstration.
A cool-feeling workpiece in one demonstration does not eliminate heat, sharp-edge, or chip hazards. Stop if the blade is damaged or control deteriorates. The beam demonstration concerns a separate supported workpiece, not an invitation to cut an installed structural member.
Carbide Reciprocating Saw Blade Prices and Value
In the video, I referenced Acme Tools listings at approximately $17 for the 6-TPI blade, $25 for the 10-TPI blade, and $22 for the 8-TPI blade. Those were filming references, not guaranteed current prices. Use the product links above to check current pricing, availability, and package quantities. Compare the cost per blade, because a discounted multipack can change the calculation for frequent users.
For someone cutting a few pieces occasionally, an appropriate bi-metal blade may be enough. For repeated demanding work, longer useful life could justify the upgrade, especially when it means fewer stops to replace blades.
Blade cost per useful cut equals purchase price divided by useful cuts before replacement. My demonstrations did not establish that final cut count, so I cannot give you a verified cost-per-cut winner.
Here’s a simple example, not a test result: a blade that costs three times as much must deliver three times the useful cuts to tie on blade cost alone. Any time saved changing blades is a separate benefit that would also need measuring.
My separate Milwaukee, Diablo, and Spyder demolition circular saw blade comparison illustrates a different comparison format. Those results do not transfer to these reciprocating saw blades.
My Takeaway: Choose the Blade, Then Judge the Value
The wood-and-nails blade gave me a smooth result, and my post-cut inspections were encouraging. The bigger lesson is selection: wood/nails, medium metal, and thick metal are different jobs.
Should I bring these back against traditional bi-metal or another brand’s carbide blades? Tell me the brand, blade type, and material, plus whether speed, lifespan, or value matters most.
For that follow-up, I would use matched stock, suitable comparison blades, and repeat cuts rather than one dramatic moment. I would want to show starting performance, how that performance changes, and why a blade is finally replaced. That would answer a different question from this introduction: not simply whether it can cut, but what useful work it delivers.

Carbide Reciprocating Saw Blades FAQ
Are carbide reciprocating saw blades worth it?
They can be, when they deliver enough useful work to justify the purchase price. My demonstrations showed suitable applications and intact teeth afterward, but not complete blade life. Consider your material, workload, existing blades, and actual replacement frequency before deciding whether the upgrade makes financial sense.
Is carbide better than bi-metal for a reciprocating saw?
Not automatically for every job. These Spyder blades use carbide-tipped teeth, while traditional bi-metal combines a steel body with a high-speed-steel cutting edge. The task and blade design matter. This introduction did not include a matched comparison establishing that carbide was faster or cheaper per cut.
Can carbide reciprocating saw blades cut thick steel?
An appropriately selected blade can handle thick-metal applications. I used Spyder’s 200372 on the steel beam. Its marking lists 3/16–9/16-inch material thickness. That is not an overall beam-size rating, and it does not establish suitability for every alloy, geometry, or installed structural cutting situation.
What TPI reciprocating saw blade should I use for metal?
Check the specific blade’s application and thickness rating rather than choosing TPI alone. Here, the 10-TPI 200375 is marked for medium metal from 1/16–5/16 inch. The 8-TPI 200372 is marked for thick metal from 3/16–9/16 inch. Those are model-specific examples, not universal tooth-count rules.
Can carbide reciprocating saw blades cut wood with nails?
Some are designed for that job. The featured 6-TPI Spyder 200438 is marked wood/nails. I demonstrated it in lumber prepared with 11 framing nails and reported smooth cutting and intact carbide tips afterward. Do not assume every carbide metal-cutting blade is equally suited to mixed demolition materials.
How long do carbide reciprocating saw blades last?
There is no lifespan established by this first look. Spyder advertises up to 60 times more cuts than standard bi-metal blades, but that is not my measured result. Material, blade selection, operating conditions, and the point at which you replace a worn blade all matter.
