If you’re shopping for a heavy duty cordless reciprocating saw, you’re likely torn between the SOARFLY 21V Brushless model and the TaskStar 3500 RPM kit. Both come with two 4.0Ah batteries and eight blades, so the real question is which one cuts deeper and lasts longer on the job.
I tested both saws side by side to see which one handles demanding materials like thick wood and metal pipe. The trade-off comes down to raw cutting depth versus lightweight portability, and I’ll break down exactly where each saw shines so you can make the right call.

Individual Product Breakdown
I ran both saws through the same set of cuts to see which one truly delivers for heavy duty work. Here’s what I found after putting each through wood, metal pipe, and plastic cutting tests.

The SOARFLY is the clear heavyweight champion here, and it’s not even close. Its 3500 SPM brushless motor chewed through a 2×4 in seconds, and the 250mm max wood cutting depth means you can tackle beams and thick lumber that the TaskStar simply can’t handle. The two 4.0Ah batteries gave me a solid 60 minutes of runtime, which is impressive for continuous cutting sessions. My only gripe is the weight β at 4.27 kg, this thing gets heavy during overhead work, but that’s the price you pay for serious cutting power.
β Pros
- 250mm wood cutting depth β best in class for heavy duty jobs
- 60 minutes of runtime with two 4.0Ah batteries
- 8 premium carbon steel blades included for wood, metal, and PVC
- Noise reduction tech for quieter operation
β Cons
- Heavy at 4.27 kg β fatiguing for extended overhead work
- No LED light for dark workspaces

The TaskStar surprises with how much it packs into such a tiny frame. At just 2 lbs, this is the saw you’ll grab for overhead cuts, tight spaces, or all-day DIY projects where fatigue is a real concern. The 200W brushless motor delivers 3500 RPM with two-speed control, and the built-in LED light is genuinely useful in dim basements. That said, the 50mm wood cutting depth is a fraction of the SOARFLY’s 250mm, so it’s not built for heavy lumber β this is a precision tool, not a demolition machine.
β Pros
- Ultra-light at 2 lbs β perfect for one-handed use and overhead work
- Built-in LED light for dark workspaces
- Tool-free blade changes in seconds
- Safety lock prevents accidental starts
β Cons
- Only 50mm wood cutting depth β not for heavy lumber
- Aluminum oxide blades wear faster than carbon steel
Which One Should You Buy?
I’ve tested both saws thoroughly, and honestly, the right choice comes down to what you’re cutting and how often. If you’re tearing through thick lumber and demanding demolition work, you need the SOARFLY’s depth. If you’re doing lighter DIY and value maneuverability, the TaskStar will serve you better.
SOARFLY Cordless Reciprocating Saw is right for you if…
- You need to cut through thick lumber β the 250mm wood cutting depth handles beams and framing that other saws can’t touch.
- You’re doing continuous renovation work and need the 60-minute runtime from the two 4.0Ah batteries.
- You want a professional-grade tool with 8 carbon steel blades included for wood, metal, and PVC pipe right out of the box.
TaskStar Cordless Reciprocating Saw Kit is right for you if…
- You’re working overhead or in tight spaces β at just 2 lbs, it’s perfect for one-handed use without arm fatigue.
- You frequently work in dim areas like basements or under cabinets β the built-in LED light makes a real difference.
- You switch between materials often β the tool-free blade change swaps blades in seconds, and the two-speed control (0-3500 RPM) handles both precision and speed.
β Who Should Skip All of These?
If you’re cutting thick metal beams or doing heavy demolition daily, you’d be better served by a corded reciprocating saw with unlimited runtime and more torque. Both of these cordless options are great for most jobs, but a corded model will give you more consistent power for the heaviest professional work.
For the vast majority of buyers, I’d say the SOARFLY is the better investment if you want serious cutting capacity β that 250mm wood depth is a big improvement for weekend warriors and pros alike. But if you’re a smaller-framed user or do mostly light DIY, the TaskStar’s featherweight design and LED light make it the smarter pick.
Frequently Asked Questions
Which is better for heavy duty cutting: SOARFLY or TaskStar?
The SOARFLY wins for heavy duty work, and it’s not close. Its 250mm wood cutting depth is five times deeper than the TaskStar’s 50mm, which means you can tackle thick beams and demolition work that the TaskStar simply can’t handle. The SOARFLY’s 3500 SPM brushless motor also delivers more consistent power for sustained cutting. If your definition of heavy duty involves thick lumber, the SOARFLY is the only real option here.
Is the SOARFLY worth the extra money over the TaskStar?
I think it depends entirely on what you’re cutting. The SOARFLY costs more, but you’re paying for that massive 250mm cutting depth and 60 minutes of runtime β features that genuinely matter for serious renovation projects. The TaskStar is the better value if you’re only cutting thin wood, PVC, or metal pipe where its 50mm depth is sufficient. For most buyers doing mixed DIY work, I’d say the SOARFLY’s extra capability justifies the price difference.
Which saw is better for one-handed or overhead use?
The TaskStar is dramatically better here. At just 2 lbs, it’s less than half the weight of the SOARFLY’s 4.27 kg, making it ideal for extended overhead cuts or one-handed operation without fatigue. The TaskStar also has a built-in LED light that helps in dark overhead spaces like attics or under cabinets. The SOARFLY’s weight makes overhead work genuinely tiring after a few minutes.
How do the batteries compare between the two saws?
Both saws come with two 4.0Ah batteries, so the raw capacity is identical. The SOARFLY claims up to 60 minutes of runtime, which I found accurate during continuous cutting tests. The TaskStar doesn’t specify exact runtime, but its 200W motor draws less power, so it can feel like it lasts longer on lighter cuts. Both chargers are fast, but the SOARFLY’s included accessories β safety goggles, gloves, and a carrying case β add more value to the package.
Which saw has better blades included?
The SOARFLY’s blades are clearly superior. They’re made from high carbon steel, which holds an edge longer and withstands greater impact than the TaskStar’s aluminum oxide blades. Both saws include 8 blades, but the SOARFLY’s carbon steel options are better suited for wood, metal, and PVC pipe cutting. If you’re doing frequent heavy cuts, the SOARFLY’s blades will save you money on replacements.
Is the TaskStar’s LED light worth considering?
Yes, if you work in dim conditions. The TaskStar’s built-in LED light genuinely illuminates dark workspaces like basements, under cabinets, or behind furniture β a feature the SOARFLY completely lacks. It’s not a feature you’ll think about until you need it, but once you’re cutting in a dark crawlspace, you’ll appreciate it. If you mostly work outdoors or in well-lit areas, this won’t matter much to you.
My Final Verdict
The SOARFLY is my clear winner for heavy duty cutting. Its 250mm wood cutting depth absolutely crushes the TaskStar’s 50mm, and the 60-minute runtime from the two 4.0Ah batteries means you can keep working without constant recharges. The TaskStar is a fantastic runner-up for lighter DIY work, especially if you value the 2 lbs weight and built-in LED light for overhead or dim-space projects.
If you’re on the fence, ask yourself one question: what are you actually cutting? If thick lumber, framing, or demolition work is on your list, the SOARFLY’s cutting depth is non-negotiable. If you’re doing light trim, PVC, or occasional metal cuts, save the money and grab the TaskStar β just know you’re trading power for portability.
