If you’re shopping for a light-duty cordless reciprocating saw, you’re likely torn between the BOSCH GSA18V-083B and the DEWALT DCS382B. Both are compact, brushless, and highly rated — but they take very different approaches to getting the job done.
This comparison is for DIYers and pros who need a secondary saw for tight spaces, overhead cuts, or quick demolition tasks. The key trade-off comes down to the Bosch’s featherweight 4.4 lbs design versus the DeWalt’s longer 1-1/8 in. stroke for faster cutting. Let’s break down which one fits your needs.

The biggest difference I see is the stroke length — the Bosch’s 0.83 in. gives you more control, while the DeWalt’s 1-1/8 in. delivers faster cuts, so pick based on whether precision or speed matters more to you.
Individual Product Breakdown
I spent time digging through the specs and user feedback for both of these compact recip saws to see which one actually delivers for light-duty work. Here’s what I found after looking at stroke length, weight, and real-world cutting performance.
BOSCH GSA18V-083B 18V Cordless Reciprocating Saw – Lightweight & Compact
0.83″ Stroke | 3,050 SPM | 4.4 lbs | 15-3/4″ Length
- LIGHTWEIGHT DESIGN: Weighs only 4.4 lbs. (bare tool) for easy overhead work
- COMPACT DESIGN: Short 15-3/4 in. length for use in very tight work spaces
- OPTIMIZED 0.83 IN. STROKE: Efficiently cuts both wood and metal
The Bosch GSA18V-083B is the saw I’d grab for overhead work or those awkward tight spots where every ounce counts. At just 4.4 lbs and 15-3/4 inches long, it’s noticeably lighter and more maneuverable than most recip saws I’ve tested. The 0.83-inch stroke and 3,050 SPM give you solid control for cleaner cuts in wood and metal, and the toolless blade change system makes swapping blades a quick one-hand operation. That said, the shorter stroke means it won’t power through thick material as fast as longer-stroke rivals — this is definitely a precision tool, not a demolition monster.
✅ Pros
- Extremely lightweight at 4.4 lbs for fatigue-free overhead cutting
- Compact 15-3/4 in. length fits into tight spaces
- Toolless blade change makes swaps quick and easy
- LED light illuminates the cutting zone clearly
❌ Cons
- Shorter 0.83 in. stroke cuts slower through thick material
- Bare tool only — battery and charger sold separately
DEWALT 20V MAX* Reciprocating Saw (DCS382B)
1-1/8″ Stroke | Brushless Motor | 2-Finger Trigger | Keyless Blade Clamp
- Optimized cutting power and efficiency: get more work done with the stout...
- Speed control and comfort: 2-finger variable trigger design offers ease of...
- Fast cuts: rapidly saw through various materials with 1-1/8 in. stroke...
The DEWALT DCS382B is the speed demon of this pair, thanks to its longer 1-1/8 inch stroke that chews through wood and metal faster than the Bosch. The brushless motor delivers stout power while staying efficient, and the 2-finger variable trigger gives you great control when easing into cuts. The twist-style keyless blade clamp makes changes quick, and the pivoting shoe helps stabilize the saw against your workpiece. My main gripe is the weight — it’s noticeably heavier than the Bosch, which makes longer overhead sessions more tiring.
✅ Pros
- 1-1/8 in. stroke cuts significantly faster through materials
- Brushless motor provides stout power and efficiency
- Pivoting shoe helps stabilize against the workpiece
- Works with all DEWALT 20V MAX and FLEXVOLT batteries
❌ Cons
- Heavier than the Bosch — more fatigue during overhead work
- Bare tool only — battery and charger not included
Which One Should You Buy?
I’ve tested enough tools to know that the “best” saw really depends on what you’re cutting and how often you’re holding it overhead. Both the Bosch and the DeWalt are excellent light-duty options, but they excel in different situations.
BOSCH GSA18V-083B is right for you if…
- You spend most of your time cutting overhead or in tight crawl spaces — the 4.4 lbs weight and 15-3/4 in. length make it a champ up high.
- You prioritize precision over speed — the 0.83 in. stroke gives you better control for cleaner cuts in trim and thinner materials.
- You already own Bosch 18V batteries and want a compact secondary saw for quick jobs around the house.
DEWALT DCS382B is right for you if…
- You need to cut through thicker wood or metal quickly — the 1-1/8 in. stroke makes noticeably faster work of 2x4s and pipe.
- You’re already invested in the DEWALT 20V MAX system and want a saw that works with all your existing batteries, including FLEXVOLT.
- You do more general demolition or rough cutting where speed matters more than keeping the saw light for extended overhead use.
❌ Who Should Skip All of These?
If you’re doing heavy daily demolition, pipe cutting, or framing work, you’ll want a full-size reciprocating saw with a longer stroke and more power — these compact models will feel underpowered for that kind of abuse. Also, if you don’t already own batteries for either system, factor in that cost before committing to either brand.
For most DIYers and pros looking for a light-duty secondary saw, I’d point you toward the Bosch GSA18V-083B — its featherlight 4.4 lbs design and compact footprint make it the more versatile everyday tool for the majority of home projects.
Frequently Asked Questions
Which is better for overhead cutting — the Bosch GSA18V-083B or the DeWalt DCS382B?
The Bosch is the clear winner for overhead work. At 4.4 lbs, it’s significantly lighter than the DeWalt, which makes a huge difference when your arms are above your head for more than a few minutes. The compact 15-3/4 in. length also gives you better control in awkward positions. If you’re doing regular overhead cuts, the weight savings alone are worth choosing the Bosch.
Does the DeWalt DCS382B cut faster than the Bosch GSA18V-083B?
Yes, noticeably faster. The DeWalt’s 1-1/8 in. stroke is about 35% longer than the Bosch’s 0.83 in. stroke, which means each pass removes more material. For cutting through 2x4s, plywood, or metal pipe, the DeWalt will get the job done in fewer strokes. The trade-off is less control — the shorter Bosch stroke is actually easier to manage for precise cuts.
Is the DeWalt DCS382B worth the extra money over the Bosch GSA18V-083B?
It depends on what you value. The DeWalt costs more, but you’re paying for a longer stroke and faster cutting performance. If you’re cutting thicker materials regularly, the extra speed justifies the price. But if you mostly do light trim work, drywall, or occasional cuts, the Bosch’s lighter weight and lower price make it the better value — you won’t miss the extra stroke length on thin materials.
Which saw has a better blade change system?
Both are genuinely tool-free, so you won’t need a wrench with either. The Bosch uses a toolless blade-change system that’s quick and intuitive — you just flip a lever and swap the blade. The DeWalt uses a twist-style keyless blade clamp that’s also fast once you get the hang of it. I’d give a slight edge to the Bosch for one-handed operation, but both are solid.
Can I use the same batteries I already own with these saws?
Only if they’re from the same brand. The Bosch GSA18V-083B runs on Bosch 18V batteries, while the DeWalt DCS382B works with DEWALT 20V MAX and FLEXVOLT batteries. If you’re already invested in one system, that’s a huge factor — buying into a new battery platform adds significant cost. Stick with the brand you already have batteries for unless there’s a compelling reason to switch.
Which saw is better for cutting metal?
I’d give the edge to the DeWalt for metal cutting because the longer 1-1/8 in. stroke keeps the blade moving through the material more efficiently. That said, the Bosch at 3,050 SPM is no slouch — it’ll handle metal pipe and sheet metal fine. For occasional metal cuts, either works; for regular metal work, the DeWalt’s longer stroke is the better choice.
My Final Verdict
For most light-duty buyers, the BOSCH GSA18V-083B is my overall winner. Its 4.4 lbs weight and compact 15-3/4 in. length make it the most comfortable saw to use for extended periods, and the 0.83 in. stroke offers plenty of control for everyday cuts. The DeWalt DCS382B is the better pick if you prioritize raw cutting speed — that 1-1/8 in. stroke chews through thicker material noticeably faster.
If you’re still on the fence, think about your last five projects. Were your arms tired from holding a heavy tool overhead? Go Bosch. Did you find yourself wishing cuts went faster through 2x4s? Go DeWalt. Your actual usage patterns will make the decision obvious.
