How to Build a Cordless Tool Wall Rack Storage

At a Glance: Cordless Tool Wall Rack Storage

This build takes 3 to 4 hours start to finish. You'll spend approximately $45–$65 on one sheet of plywood plus finish. Skill level is beginner-friendly; if you can run a circular saw and a drill, you're good. The result is a wall-mounted tool organizer with 4 tool bays and an integrated charging shelf.

What You're Building

Picture a wall-mounted shelf with a row of upside-down “T” shapes along the bottom. Each T has a flat piece that sits on the shelf (the T-Spacer) and an upright piece that sticks up (the Vertical Divider). The gaps between these upright pieces are your tool slots; your drills hang handle-down in those gaps.

Above the tool slots, there's a second shelf for your battery charger, with a hole in the back for the cord to drop through and stay hidden.

That's it. A box, two shelves, and four or five T-shaped dividers.

Why Build Your Own Cordless Tool Wall Rack?

Store-bought drill racks use oversized 3-inch slots designed to fit “any tool.” The problem is that 3 inches is too loose for most cordless drills. Your impact driver wobbles, slides forward, and eventually nose-dives onto your workbench.

This DIY drill storage rack uses a T-slat system with 2″ slots wide enough for any standard drill or impact driver, snug enough to eliminate wobble. Works with DeWalt, Milwaukee, Makita, Ryobi, or a mix of all four.

You'll also add a built-in tool charging station DIY style a dedicated shelf for your charger with a grommet hole for cord management. Batteries stay topped off without cluttering your bench.

Build Steps

Step 1: Cut and Sand
If you don't have a table saw, a circular saw with a straightedge guide works for all main cuts. Sand all edges with 120-grit sandpaper before assembly to remove splinters and help your paint stick.

Step 2: Build the T-Slat Assemblies
Lay one T-Spacer flat. Stand a Vertical Divider upright on the center point, apply wood glue, and drive two 1½” screws through the bottom of the spacer into the divider. Repeat for all five assemblies.

Screws are great for holding things in place, but glue is what actually makes a project like this last for a decade. I always reach for titebond because it gives me a few extra minutes of ‘wiggle room' to get those tool slots perfectly aligned before the glue hardens.

Optional improvement: Bevel or round the front edges of the T-Spacers with sandpaper or a router. This makes sliding tools in and out smoother.

Step 3: Assemble the Box

Build order matters. Attach pieces in this sequence:

1. Lay the Back Panel (19.5″ x 12.2″) flat on your workbench.
2. Attach the two Side Panels (9.8″ deep) to the left and right edges of the Back Panel using wood glue and 1½” screws (3 screws per side). The Side Panels should be flush with the back and extend forward 9.8″.
3. Measure 5½” up from the bottom inside edge of each Side Panel. Mark a line. This is where the top of your Bottom Shelf sits.
4. Install the Bottom Shelf at that line using wood glue and 1½” screws through the Side Panels into the shelf ends (2 screws per side).
5. Measure 5½” up from the top of the Bottom Shelf. Mark a line. This is where your Middle Shelf sits.
6. Install the Middle Shelf the same way.
7. You now have a box with two shelves inside.

Step 4: Drill the Cord Grommet Hole

Before the dividers go in, drill a 1½” hole in the back corner of the Middle Shelf. Position the hole about 2″ from the back edge and 2″ from one side for cord management.

Since you’re building a custom shelf for your chargers, you need a power source that’s as tough as your tools. I dig this metal strip because those big power tool chargers always take up more room than they should, and the wide spacing here actually lets you use every outlet without them blocking each other. Here's what I use:

Step 5: Install the T-Slat Assemblies

This is where your precision spacing matters to ensure a snug, “wobble-free” fit for your tools. Instead of a single 2″ jig, cut two scrap blocks: one exactly 1.4″ wide and one exactly 1.6″ wide.

Installation sequence:

1. Start at the left side of the Bottom Shelf.
2. Measure 3.3″ from the left exterior edge of the rack and make a pencil mark.
3. Place your first T-assembly with the left edge of its Vertical Divider on that mark. The Vertical Divider must face up.
4. Apply wood glue to the bottom of the T-Spacer and screw it down with two 1½” wood screws.
5. Place your 1.4″ spacer block against the right side of the Vertical Divider.
6. Butt the next T-assembly's Vertical Divider against that spacer block.
7. Remove the spacer, then glue and screw the assembly down.
8. Switch to your 1.6″ spacer block for the next three middle gaps.
9. Finish with the 1.4″ spacer block for the final slot on the right side.
10. Repeat until all five T-assemblies are installed.
11. You should end with a 3.3″ section on the far right side of the rack.

Check your work: You should have two 1.4-inch gaps on the ends and three 1.6-inch gaps in the middle. If a gap looks off, remove and reposition it before the glue dries.

Step 6: Add Compact Battery Storage (Optional)

If you use stick-style batteries (common on 12V compact tools), drill two or three 1″ holes into the left exterior Side Panel. Space them about 3″ apart vertically. Batteries slide in and stay put.

Finish the Rack

Do this before mounting it to the wall. It's easier to paint a rack on your workbench than on the wall.

1. Sand any rough spots with 120-grit sandpaper.
2. Prime with one coat of spray primer. Let dry 1–2 hours.
3. Paint two light coats of spray paint. Let dry between coats.
4. Label your slots with a paint pen if desired: DRILL, IMPACT, DRIVER.

I know it’s tempting to jump straight to driving screws, but I always regret it if I don't sand the plywood edges first. I use a high-quality 120-grit paper to knock down splinters and bevel the front edges of the tool slots.

Mount the Cordless Tool Wall Rack

Critical: Anchor into at least two wall studs. Cordless tools plus batteries can exceed 30 pounds. Drywall anchors alone will fail.

How to mount:

1. Use a stud finder to locate two studs. Mark them with painter's tape.
2. Hold the rack against the wall at your desired height. Have a helper hold it or use a temporary cleat.
3. Drive one 3″ screw through the Back Panel into a stud. Don't tighten fully.
4. Check level. Adjust the rack until it's straight.
5. Drive a second 3″ screw into the other stud.
6. Drive two more screws (4 total) for security.
7. Tighten all screws.

Mounting height tip: Position the rack so your tool handles hang at roughly chest height. This makes grabbing tools comfortable and keeps heavy items at a stable height.

Safety Notes

• Wear safety glasses when cutting and drilling.
• Use hearing protection with power saws.
• Wear a dust mask as plywood dust irritates the lungs.
• Ensure your rack is anchored into studs. Drywall-only mounting will fail.

FAQs About Cordless Tool Wall Rack

How much weight can this cordless tool wall rack hold? Mounted into two studs with 3″ screws, this rack safely holds 40+ pounds enough for 4 cordless tools plus batteries and a charger.

Will the 2″ slots fit my tools? Yes. The 2″ slot width fits standard drills and impact drivers from DeWalt, Milwaukee, Makita, and Ryobi. If you have a high-torque impact or angle grinder with a larger handle, measure the neck and widen your end slot to 2½”.

Can I make this bigger for more tools? Yes. Extend the Back Panel width to 36″ or 48″ and add more T-assemblies. Keep the 2″ slot gaps and 3″ center-to-center spacing throughout.

Do I need a table saw? No. A circular saw with a straightedge guide works for all the main cuts. For the ½” T-Spacers, ask the hardware store to rip a ½” strip for you, or cut carefully with a circular saw and clamped guide.

What's the best way to mount the charger? Most chargers have keyhole slots on the back. Drive two pan-head screws into the back edge of the Middle Shelf, spaced to match the slots. Slide the charger onto the screws so they'll lock in place and won't lift off when you pull a battery.

How do I keep batteries from draining while stored? Modern lithium batteries have built-in discharge protection. Storing them at 30–50% charge extends lifespan. An auto-off power strip prevents chargers from cycling unnecessarily when batteries are full.
