DeWalt TrackSaw T-Square

What it is and who it’s for

The TrackSaw T-square is a simple accessory that solves a very specific problem: making fast, dead-square crosscuts off the edge of sheet goods and panels with a track saw. If you already rely on a track saw to break down plywood or trim doors, this little add-on turns the long guide rail into a reliable 90-degree fence. It’s not a flashy tool—no knobs to twiddle, no digital readouts—but it fills a gap between freehand layout and full-blown panel saw setups.

I put it to work on cabinet carcass parts, shelves, toe kicks, and door trims—any task where I needed repeatable square cuts without rolling a table saw into the middle of the room. It shines for jobsite carpentry and small shops where space and time matter.

Setup and first impressions

Out of the box, the T-square is compact and light (just over a pound), with a clean, silver finish and a straightforward profile. It attaches to the DeWalt TrackSaw rail and engages with a self-aligning mechanism that sets the rail square to the workpiece edge. Installation is tool-less and takes a few seconds. There’s nothing to calibrate or chase; the whole point is you don’t need to square it yourself each time.

On my rails, the fit was snug and positive—no rattling or slop—so once I pushed it home, it seated consistently. The footprint of the “T” against the panel edge is modest but sufficient. It doesn’t feel like a long framing square; it’s more of a compact reference block. I like that it doesn’t interfere with the anti-slip strips or the underside clamp channels on the rail.

Accuracy and repeatability

The critical question: does it actually produce square cuts? In use, yes. It’s easy to trust the registration—press the T-square against the panel’s reference edge, place the rail, and you’re ready to cut. I checked results with a machinist’s square over repeated cuts and found no measurable drift. For cabinet parts that need to stack up perfectly, it gave me the consistency I need.

There’s no micro-adjustment for “almost square” rails or out-of-true material. That’s by design. If the reference edge is true, the cut is true. If the edge is dinged or bowed, the T-square will faithfully register to that imperfection. That’s not a downside so much as a reminder to prep the edge you’re registering against. I often kiss an edge with a jointer plane or clean it up with the track saw freehand before relying on the T-square for final, dimensionally critical cuts.

In the shop: practical use cases

• Breaking down plywood: I used it to square off factory edges and then cut repeated shelf lengths. Not having to pencil and align square lines made the process much faster.
• Trimming doors: For shaving a clean, square end off a solid or hollow-core door, the T-square provides a confident reference without wrangling a door against a miter gauge or fence.
• Cabinet carcass parts: Side panels and stretchers were quick to batch—register, cut, repeat—without cumulative error creeping in.
• Squaring after glue-ups: For panels that needed a true corner post-glue, I could trim a whisker off and know I was bringing the corner to 90.

In practice, I relied less on clamps than I expected. The anti-slip strips on the rail and the positive registration of the T-square are often enough for short cuts. For long panels or slick melamine, I still use low-profile track clamps in the underside channel. The T-square sits at the end of the rail, so it doesn’t fight the clamps.

Ergonomics and build quality

It’s a tidy piece of machined and formed metal, with no flex or rough edges. DeWalt typically nails the interface design on its TrackSaw ecosystem, and this follows suit. There aren’t many moving parts to fail, which I appreciate in an accessory that’ll live in a tool bag.

At 13.1 inches long and just over five and a half inches wide, it packs easily alongside the rail or in a systainer-style box. The light weight is a plus on-site, and it doesn’t tip the rail out of balance or make setup awkward.

If I have a nitpick, it’s the short warranty window (90 days). Accessories like this aren’t high-risk items, but I’d like to see a longer tail, especially when accuracy is the value proposition. That said, the simplicity of the design leaves very little to go wrong.

Compatibility and workflow

The T-square is designed for DeWalt’s TrackSaw system. On my rails, compatibility was a non-issue; it seats correctly and indexes reliably. I wouldn’t expect it to cross over to non-DeWalt rails without buyer’s remorse. The accessory is purpose-built to engage specific profiles and tolerances.

For workflow, the biggest gain is speed. Traditional layout involves marking a square line, aligning the rail to the line, and verifying. With the T-square, I skip most of that: register to the edge, bring the rail to the mark, and cut. Over a day of cutting, that time adds up. More importantly, the lack of manual alignment reduces the chance of introducing small errors that accumulate over a run of parts.

Limitations and things to know

• It’s 90 degrees only: If you need 45s or compound angles, this isn’t the tool. It’s a single-purpose square reference for perpendicular cuts.
• Edge quality matters: The T-square is only as true as the edge it registers against. If the panel edge is out, the cut will be out by the same amount.
• Rail straightness is still king: The accessory doesn’t correct a bent rail. Make sure your guide is straight and your splinter guard is clean and intact.
• No fine adjustment: There’s no dial to “nudge” the angle. If your workflow demands tuning to a specific reference square beyond what the accessory provides, you’ll need to adjust the process rather than the tool.
• Space at the edge: On narrow stock, the T registration may not have enough material to bear against. It really excels on sheet goods and wide panels.

Tips to get the most out of it

• Establish a true reference edge first. One quick cleanup pass makes the T-square’s precision pay off.
• Keep the underside of the rail clean. Dust and chips under the anti-slip strips can throw things out.
• Use clamps for slick surfaces or long rips that risk rail movement. The T-square plays nicely with underside clamps.
• Check square occasionally with a reliable reference. Not because the T-square drifts, but because it’s good practice in any precision workflow.
• Mark from a consistent edge throughout a project. By always registering the T-square to the same reference edge, you avoid compounded errors.

Bottom line

The TrackSaw T-square is an unassuming but genuinely useful addition to a track saw kit. It turns your rail into a repeatable 90-degree fence that speeds up layout, reduces chances for error, and delivers square cuts with minimal fuss. Setup is essentially instant, accuracy is dependable, and the build quality inspires confidence. It doesn’t try to be more than it is, and that’s precisely why it works so well.

Recommendation: I recommend it for anyone already invested in DeWalt’s track saw system who regularly breaks down sheet goods or trims panels on site. The time saved in layout and the repeatability it brings to square cuts is worth it. If your work is heavy on angled cuts or you primarily use a table saw sled for panels, you’ll see less value here. But for cabinet installers, finish carpenters, and small-shop woodworkers who want square, fast, and repeatable crosscuts off a rail, this accessory earns its keep.
