The Essential Four: Tools You Cannot Build a Deck Without
1. Circular Saw — DeWalt DCS573B
Price: $225 | Why it’s essential: Every deck board, joist, and post needs to be cut to exact length. A circular saw is the only efficient way to do this.
The DeWalt DCS573B is a 7-1/4″ cordless circular saw running on the 20V MAX XR platform. It delivers 5,800 RPM with a brushless motor — enough to rip through 2x lumber, PT boards, and composite decking without bogging down. The left-blade design gives you a clear line of sight to your cut mark, which matters when you’re making 100+ cuts over a build weekend.
For deck work specifically: the bevel capacity goes to 57° for angled cuts at stairs and railings. The tool-free depth adjustment handles everything from 1-inch deck boards to 2×8 joists. At 6.8 lbs (bare), it’s manageable for a full day of cutting without shoulder fatigue.
Pros
- Left-blade design: cut line is clearly visible
- Brushless motor handles PT lumber without hesitation
- 20V MAX battery — shares with drills, impact drivers, jigsaws
- 57° bevel for stair and railing angles
Cons
- Bare tool only — need 20V battery separately (included in DCK299P2 kit)
- $225 is mid-range; budget option: DeWalt DCS565B (~$129) if cuts per charge isn’t critical
See our full Best Circular Saws 2026 guide for alternatives.
2. Drill/Driver — DeWalt DCD771C2
Price: $99 (kit with 2 batteries + charger) | Why it’s essential: Pilot holes prevent deck boards from splitting. You’ll drill hundreds of them.
The DCD771C2 is DeWalt’s entry-level 20V MAX drill, but “entry-level” undersells it for deck work. 300 UWO of power handles 3/8″ pilot holes in PT lumber all day. The 24-position clutch prevents overdriving when you switch from pilot holes to driving deck screws directly. Two-speed gearbox: use low speed (0-450 RPM) for controlled driving, high speed (0-1,500 RPM) for fast drilling.
The kit includes two 1.3Ah batteries and a charger — the only tool on this list that comes complete out of the box at $99. If you’re starting a DeWalt 20V MAX collection from scratch, this is where to begin. The batteries will also power the DCF850B impact driver and DCS334B jigsaw.
Pros
- $99 with two batteries and charger — best value entry point
- 24 clutch positions for precise torque control
- Starts the DeWalt 20V MAX ecosystem
Cons
- 1.3Ah batteries are small — heavy users should upgrade to 2.0Ah
- Brushed motor: less efficient than brushless, but fine for intermittent deck use

3. Impact Driver — DeWalt ATOMIC DCF850B
Price: $114.98 (bare tool) | Why it’s essential: Driving 3-inch deck screws through hardwood boards with a drill will destroy your wrist and strip every head. An impact driver does it effortlessly.
The DCF850B is DeWalt’s ATOMIC compact impact driver — 1,825 in-lbs of torque in a 4.1-inch body. That’s more torque than most deck screws will ever need, and the compact length means you can drive screws in tight joist bays where a full-size driver won’t fit.
The 3-speed electronic transmission is the key feature for deck work: Speed 1 (0-1,000 RPM) for precision driving near edges, Speed 2 (0-2,800 RPM) for standard work, Speed 3 (0-3,300 RPM) for max speed. The LED work light illuminates screw holes in shadowed joist bays. At 2.0 lbs bare, it won’t fatigue your wrist even after driving 500+ screws in a day.
Pros
- 3-speed electronic control prevents overdriving near board edges
- 1,825 in-lbs — more than sufficient for 3″ structural screws
- Compact body (4.1″) fits tight joist bays
- Uses same 20V MAX batteries as DCD771C2 and DCS573B
Cons
- Bare tool only — needs separate 20V MAX battery
- If you’re buying drill + impact driver separately, the DCK299P2 combo kit saves ~$50
See our Best Impact Drivers 2026 for head-to-head comparisons.
4. Tape Measure — Klein Tools 9225
Price: $29.98 | Why it’s essential: Measure wrong once, and you’ve wasted an $8 deck board and 10 minutes of your day.
The Klein 9225 is a 25-foot tape with a 1-1/4″ wide blade and 13-foot standout — it holds rigid long enough to span a 2×6 deck board without the blade buckling. The magnetic tip grabs metal framing connectors and joist hangers for one-person measurements. The mylar-coated blade resists the abrasion of concrete and PT lumber that destroys cheap tapes within a season.

The Upgrade Tools: Worth Getting If You’re Doing It Right
5. Jigsaw — DeWalt DCS334B
Price: $140.95 (bare tool) | Best for: Stair stringers, post notches, angles around obstacles
You’ll need a jigsaw the moment you hit stair stringers, curved railing sections, or cuts around existing posts and structural elements. The DCS334B delivers variable speed (0–3,000 SPM) with tool-free bevel adjustment to 45° in both directions. The brushless motor maintains speed through composites and pressure-treated lumber that bog down cheaper saws. For a deck build, the jigsaw is the “sometimes” tool — but when you need it, no other tool substitutes.

6. Laser Level — Fanttik D2
Price: $39.99 | Best for: Leveling ledger boards, laying out post positions, checking deck frame square
A deck that isn’t level from the start will never be level. The Fanttik D2 is a self-leveling cross-line laser with ±4° self-leveling range and ±1/8″ accuracy at 33 feet. At $39.99, it’s one of the highest-ROI tools in this guide — catching a 1/4″ out-of-level ledger before you frame the whole deck prevents a complete teardown later.
The magnetic base mounts to any metal framing member. Battery-powered (AA batteries, no recharging required on site). The red laser is visible in shaded areas but loses visibility in direct sunlight — plan your layout work for morning or overcast conditions.

7. Orbital Sander — Optional for Hardwood Decks
If you’re building with composite decking (Trex, TimberTech), skip the sander. If you’re using hardwood or cedar, a random orbital sander removes mill glaze and opens the grain for better stain penetration. See our Best Sanders 2026 guide for current picks.
Kit vs Individual Tools: The Math
If you don’t own any 20V MAX tools, the DeWalt DCK299P2 combo kit ($368.50) gives you the DCD996 hammer drill and DCF887 impact driver with two 5.0Ah batteries and a charger — for less than buying those tools and batteries separately. You’d then add the DCS573B circular saw and DCS334B jigsaw as bare tools, sharing the batteries.
The Best Cordless Combo Kits 2026 guide covers what’s included at each price point.
| Path | Cost | Best for |
|---|---|---|
| DCK299P2 kit + DCS573B bare + DCS334B bare | ~$649 | Starting from scratch — best battery ROI |
| DCD771C2 kit + DCF850B bare + DCS573B bare + DCS334B bare | ~$580 | Budget build — works, but small batteries |
| Individual bare tools + 1x 5.0Ah battery | ~$600+ | Expanding existing 20V MAX collection |
Battery Platform: Why Your First Tool Choice Matters
Every tool on this list runs on DeWalt 20V MAX batteries. That’s intentional — deck work requires 3–4 tools running simultaneously, and shared batteries mean you never stop to hunt a charger. Milwaukee M18, Makita 18V LXT, and Ryobi ONE+ all work the same way, but DeWalt 20V MAX offers the widest tool selection on Amazon at consistent pricing.
If you already own Milwaukee M18 or Makita 18V tools, buy bare tools from that platform instead. The battery compatibility is more valuable than any specific model recommendation. See our Battery Platforms Compared 2026 guide for the full breakdown.

Frequently Asked Questions
What tools do I need to build a deck?
The minimum set is: circular saw, drill/driver, impact driver, and tape measure. For stairs and curves, add a jigsaw. For accurate post layout, add a laser level. All six tools can be had for under $650 in 2026 starting from scratch.
Do I need both a drill and an impact driver?
Yes — they serve different purposes. The drill handles pilot holes (critical for preventing split boards). The impact driver drives the deck screws with high torque and no cam-out. Using one tool for both jobs is slower and harder on your wrist. See our Impact Driver vs Drill guide for the full comparison.
What’s the best cordless circular saw for deck work?
The DeWalt DCS573B ($225 bare) is the best all-around choice for 2026. Left-blade design keeps the cut line visible, brushless motor handles PT lumber without bogging down, and it runs on 20V MAX batteries shared with the rest of your tool set.
Combo kit or individual tools?
Starting from scratch: get the DeWalt DCK299P2 combo kit (~$368) for drill + impact driver + 2 batteries, then add the DCS573B and DCS334B as bare tools. You’ll spend about $650 total and own a full battery-compatible cordless set.
How many deck screws does a typical project need?
A 12×16 deck uses 400–600 deck screws plus framing hardware. This is why an impact driver is non-negotiable — driving that many screws through PT lumber with a drill will fatigue your wrist and strip heads. The DCF850B handles this workload without effort.
