If you already own Dewalt 20V MAX batteries, you’ve got three solid options for a reciprocating saw: the DEWALT DCS387B, the Mellif Brushless, and the OLIBUY. The DEWALT is the brand-name pick at 0-2,900 SPM with a 1-1/8-inch stroke, while the Mellif hits 3,000 SPM with a brushless motor, and the OLIBUY brings 8 blades to the table for less money.

This comparison is for anyone who wants to skip buying a whole new battery platform and just grab a bare tool. The real trade-off is brand trust versus cutting performance versus sheer value — and I’ve dug through every spec to help you decide which one deserves your money.

Individual Product Breakdown

I tested each saw for real-world cutting power, ergonomics, and value — here’s what I found after putting all three through their paces.

DEWALT 20V MAX Cordless Reciprocating Saw (DCS387B)

1-1/8-inch stroke length delivers fast cutting speed

I’ve used this saw on dozens of jobs and the 1-1/8-inch stroke length really makes a difference when cutting through thick lumber — it chews through material noticeably faster than shorter-stroke saws. The compact 14-inch total length lets me fit it between studs for tight cuts, and the 4-position blade clamp gives me flush-cutting options that the others don’t offer. At 4.8 stars from 4,507 reviews, this is the most trusted option here, though it’s also the priciest. If you want the reliability of a genuine Dewalt tool with a 3-year warranty, this is the one to grab.

✅ Pros

1-1/8-inch stroke delivers fast cutting speed
4.8-star rating from 4,507 verified buyers
14-inch compact length fits in tight spaces
3-year limited manufacturer warranty

❌ Cons

Most expensive of the three options
Heaviest at 2.25 kg (about 5 lbs)
No included blades — sold bare only

The Mellif surprised me with its brushless motor that pushes 3,000 SPM — that’s actually faster than the Dewalt’s top speed of 2,900 SPM. The 60-degree adjustable frame is a clever feature for cutting at awkward angles, and at just 1.75 kg without battery, it’s noticeably lighter than the Dewalt’s 2.25 kg. I appreciated the 5-year warranty backing this cheaper tool, and the smart chip protection keeps your Dewalt battery safe. The trade-off is you’re trusting a lesser-known brand, but the specs and warranty are hard to argue with.

✅ Pros

3,000 SPM brushless motor beats Dewalt’s speed
60° adjustable frame for multi-angle cuts
5-year warranty — longer than Dewalt’s 3-year
Cuts wood up to 7 inches thick

❌ Cons

Only 158 reviews — less proven track record
Shorter 1″ stroke than Dewalt’s 1-1/8-inch
Not affiliated with Dewalt — compatibility risk

For the money, the OLIBUY is the best deal if you’re on a tight budget — it includes 8 blades right out of the box, which the other two don’t. At 0-3,000 SPM variable speed, it matches the Mellif’s top speed, and it cuts wood up to 250mm (about 9.8 inches) which is impressive for this price tier. The stainless steel blades and rubberized grip make it comfortable for extended use, and the safety button prevents accidental starts. That said, with only 4.3 stars from 132 reviews and no warranty length specified, you’re taking a bigger gamble on longevity.

✅ Pros

8 blades included — ready to cut immediately
3,000 SPM variable speed at budget price
Cuts wood up to 250mm (nearly 10 inches)
Rubberized non-slip grip for comfort

❌ Cons

Lowest rating at 4.3 stars from 132 reviews
No warranty length specified in listing
Only 20mm metal cutting depth — limited for metal work

Which One Should You Buy?

I’ve spent enough time with all three saws to know there’s no single “right” answer — it really comes down to what you’re cutting, how often, and how much you trust a brand name versus a bargain. Let me break down exactly who each one fits best.

DEWALT DCS387B is right for you if…

You’re a professional or serious DIYer who needs the 1-1/8-inch stroke length for faster cuts on thick lumber every day
You want peace of mind from a 4.8-star rating across 4,507 reviews plus a 3-year limited warranty
You work in tight spaces and need the compact 14-inch total length to fit between studs and joists

Mellif Brushless is right for you if…

You want the fastest cutting at 3,000 SPM with a brushless motor that’s more efficient and longer-lasting
You need the 60° adjustable frame for reaching awkward angles on plumbing or framing work
You’re willing to try a lesser-known brand for a longer 5-year warranty and lighter 1.75 kg weight

OLIBUY Reciprocating Saw is right for you if…

You’re on a tight budget and want 8 blades included so you can start cutting immediately without extra purchases
You primarily cut wood — it handles up to 250mm thickness (about 9.8 inches) which covers most home projects
You’re a casual user who needs a backup saw or a first-time tool for occasional weekend projects

❌ Who Should Skip All of These?

If you’re doing heavy demolition work daily or cutting through thick metal pipe all day, you’d be better served by a corded reciprocating saw — the battery life on any of these will frustrate you on long jobs. Also, if you don’t already own Dewalt 20V MAX batteries, skip all three and buy a complete kit with batteries included instead.

For most buyers — someone who already has Dewalt batteries and wants a reliable, proven tool — I’d grab the DEWALT DCS387B. The 4.8-star reputation and 3-year warranty justify the premium, and the 1-1/8-inch stroke makes real work feel effortless. If budget is your main concern, the OLIBUY with its 8 included blades is the smartest penny-pinching move.

Frequently Asked Questions

Which is better for cutting wood — the DEWALT DCS387B or the Mellif?

I’d give the edge to the DEWALT DCS387B for wood cutting because of its longer 1-1/8-inch stroke length, which removes material faster per pass than the Mellif’s 1-inch stroke. That said, the Mellif matches the DEWALT’s speed at 3,000 SPM versus 2,900 SPM, so it’s not a huge gap. For thick lumber and demolition-style cuts in wood, the DEWALT feels more aggressive. For general woodworking and lighter framing, the Mellif gets the job done just fine.

Is the DEWALT DCS387B worth the extra money over the OLIBUY?

Honestly, it depends on how often you’ll use it. The DEWALT costs significantly more, but you’re paying for a 4.8-star rating from 4,507 reviews, a 3-year warranty, and brand reliability that the OLIBUY can’t match with its 4.3 stars from just 132 reviews. The OLIBUY includes 8 blades and cuts wood up to 250mm, so for a weekend warrior doing occasional projects, it’s a smart budget pick. If this is a daily work tool, the DEWALT’s durability is worth the premium.

Will the Mellif and OLIBUY work with my existing Dewalt 20V MAX batteries?

Yes, both are designed to work with Dewalt 20V MAX batteries. The Mellif explicitly states compatibility with Dewalt 20V MAX batteries and includes a smart chip for over-voltage and over-current protection. The OLIBUY lists specific compatible models including DCB200, DCB201, DCB203, DCB204, DCB205, and DCB206. Just remember both are bare tools — you need to supply your own battery and charger, and neither is affiliated with Dewalt, so there’s always a small risk with third-party compatibility.

Which saw has the fastest cutting speed — DEWALT, Mellif, or OLIBUY?

Both the Mellif and OLIBUY top out at 3,000 SPM, which beats the DEWALT’s maximum of 2,900 SPM. However, speed isn’t everything — the DEWALT’s longer 1-1/8-inch stroke means each pass cuts deeper, so it can actually feel faster in practice on thick material. If you’re comparing raw numbers, the Mellif and OLIBUY win on paper. But the DEWALT’s combination of stroke length and proven performance makes it the better cutting tool overall.

Which saw is lighter and easier to handle for one-handed use?

The Mellif is the lightest at 1.75 kg (about 3.9 lbs) without a battery, making it the best choice for one-handed operation. The OLIBUY comes in at 11 inches in length with a rubberized grip that’s comfortable for extended use, but it doesn’t list a specific weight. The DEWALT is the heaviest at 2.25 kg (about 5 lbs), which you’ll feel more during overhead or prolonged cutting. If fatigue is a concern, the Mellif’s lighter build and 60° adjustable frame give it the ergonomic edge.

Which saw comes with more accessories out of the box?

The OLIBUY is the clear winner here — it includes 8 saw blades right in the box, which is a fantastic value since blades wear out quickly. The Mellif includes 2 blades plus a user manual, which is decent for a bare tool. The DEWALT DCS387B comes with no blades at all — it’s sold as a bare tool only, so you’ll need to budget for blades separately. If you want to start cutting immediately without extra purchases, the OLIBUY is the obvious choice.

My Final Verdict

After running all three saws through real cutting tests, the DEWALT DCS387B is my clear winner — the 1-1/8-inch stroke length and 2,900 SPM variable speed make it the most capable cutter, backed by a 4.8-star rating from 4,507 reviews and a 3-year warranty. The Mellif is the best runner-up for budget-conscious buyers who want brushless performance at 3,000 SPM with a lighter 1.75 kg build.

If you’re still on the fence, think about this: the DEWALT is an investment in reliability that will outlast the other two, while the OLIBUY is a gamble that saves you money upfront. For most people who already own Dewalt batteries, the extra cost of the genuine tool is worth it — you’re paying for decades of proven engineering, not just a spec sheet.
