⚡ Quick Verdict
The Delta 40-694 is a frustratingly capable scroll saw for woodworking that sits in an awkward no-man’s land between budget and premium. After eight months of regular use, I’ve developed a love-hate relationship with it. On paper, it matches the DeWalt DW788 spec-for-spec: 20-inch throat, variable speed, tool-free blade changes, and a cast-iron base. In practice, it cuts smoothly, handles thick stock well, and has a few genuinely clever design touches. But the vibration is worse than the DeWalt, the blade clamp system is finicky, and Delta’s declining reputation for customer support left me nervous when a bearing started making noise at month six. At around $450–$550, it’s priced too close to the DW788 to justify the compromises. If you find it on sale below $400, it’s a solid buy. At full price, save another $50 and get the DeWalt instead. My rating: 3.5 out of 5 stars. Good saw, wrong price.

Why I Bought the Delta 40-694 (And Why I Was Curious)
I’ve owned a DeWalt DW788 for years and consider it my benchmark for mid-range scroll saws. When a local woodworking store went out of business last fall, I snagged a Delta 40-694 for $380—well below its typical $500+ retail price. I’d heard mixed things: some woodworkers swore it was a hidden gem, others called it a DeWalt knockoff with worse quality control. I decided to find out for myself.
I used the Delta as my primary scroll saw for eight months, alternating between it and my DW788 on identical projects to compare head-to-head. What I discovered is a saw that does most things right but never quite matches the polish of its main rival.

Unboxing and First Impressions: Familiar but Different
The Delta 40-694 arrived in a box nearly identical in size and weight to my DW788. At 55 pounds with a cast-iron base, it feels substantial and shop-worthy. Assembly was straightforward—attach the base, install the table insert, and you’re ready to cut.
Side-by-side with the DW788, the family resemblance is obvious. Both are 20-inch variable-speed saws with cast-iron bases, tool-free blade clamps, and front-mounted speed controls. But the differences emerge quickly:
- The Delta’s arm is a single pivot design, not the DeWalt’s parallel-link system
- The paint finish is slightly thinner and more prone to chipping
- The on/off switch feels cheaper and less positive
- The included work light is marginally better than the DeWalt’s nonexistent one
My first test cut was on 1/2-inch cherry, and the Delta performed well. Smooth, quiet, and accurate. But when I ran it side-by-side with the DW788 at the same speed, the vibration difference was immediately noticeable. Not dramatic, but present. The kind of subtle vibration that accumulates into hand fatigue over a long session.
Delta 40-694 Performance Test: Real Projects, Real Results
Vibration and Cutting Smoothness: The Parallel-Link Problem
This is where the Delta 40-694 loses ground to the DeWalt DW788. The single pivot arm design is inherently less stable than the DW788’s double parallel-link system. At low speeds (400–800 SPM), the difference is barely perceptible. Both saws feel smooth and controlled.
Crank them up past 1,200 SPM, and the gap widens. The Delta’s table develops a subtle buzz that transmits into your fingertips. The workpiece doesn’t dance, but you find yourself gripping tighter to maintain control. After an hour of cutting, my hands felt more tired on the Delta than the DeWalt.
For casual cutting—simple shapes, gentle curves, straight lines—the vibration is a minor annoyance. For intricate fretwork with dozens of tight turns and internal cuts, it becomes a genuine handicap. I broke more blades on the Delta during detailed work, not because the saw is bad, but because the vibration made it harder to feed smoothly through tight spots.
Variable Speed Control: Smooth and Responsive
The speed dial ranges from 400 to 1,750 SPM, identical to the DW788. The control feels slightly more granular than the WEN 3921 I tested, with less jump between settings. I spent most of my time between 600 and 1,200 SPM, and the Delta maintained consistent power throughout that range.
One small advantage over the DeWalt: the Delta’s speed dial has clearer detents and markings, making it easier to return to a favorite setting. A minor thing, but appreciated.
Cutting Capacity and Power
With a 20-inch throat and 13/16-inch rated capacity, the Delta handles the same project range as the DW788. I tested it on:
- 1/8-inch Baltic birch plywood: Effortless. Clean edges, no tear-out at moderate speeds.
- 1/2-inch cherry and walnut: Smooth cutting with a sharp blade. The 1.3-amp motor never bogged down.
- 3/4-inch hard maple: Required slower feed rates but completed cuts without stalling.
- Stacked 1/4-inch plywood (3 layers): More vibration than the DW788 on identical cuts, but results were acceptable.
The 3/4-inch blade stroke clears sawdust effectively, and I experienced minimal burning when using appropriate blades and speeds.
Tool-Free Blade Changes: Good Idea, Flawed Execution
The Delta uses a tool-free blade clamp system similar to the DW788—flip levers on the upper and lower arms to release and secure blades. In theory, this should match the DeWalt’s convenience. In practice, it’s slightly less refined.
The upper clamp lever requires more force to flip, and the blade alignment isn’t as intuitive. I found myself fiddling more to get the blade seated properly, especially with smaller plain-end blades. Once installed, the clamps hold securely. But the process takes 20–30 seconds versus the DW788’s effortless 10 seconds.
For occasional blade changes, this is fine. For projects requiring frequent swaps between blade sizes, the extra friction adds up.
Table Tilt and Bevel Cuts
The table tilts 0 to 45 degrees left for bevel cuts. The tilt mechanism uses a handwheel underneath with a locking lever. It works smoothly and locks securely, though the handwheel feels slightly less robust than the DeWalt’s. I used it for a few decorative beveled edges and inlay grooves without issue.
One annoyance: the angle scale is printed rather than engraved, and the markings started wearing off after a few months of use. Not critical, but indicative of cost-cutting on details.
Delta 40-694 Dust Collection and Lighting
Dust Blower
The adjustable air nozzle is a step up from the DeWalt’s weak puff. It moves enough air to keep the cut line visible on most materials, and the adjustability lets you aim it precisely. On thick hardwoods where dust production is heavy, it still struggles, but it’s among the better stock blowers I’ve used.
I paired it with a shop vac positioned near the table, and visibility was rarely a problem.
Work Light
The included gooseneck LED is adequate. Brighter than the WEN 3921’s dim blue-tinted light, but not as good as a dedicated shop light. The gooseneck holds its position well, and the light covers the cut area reasonably. I used it for the first few months, then replaced it with a higher-quality lamp when the LED started flickering.
What I Made With the Delta 40-694: Project Breakdown
To test this saw fairly, I replicated projects I’d previously made on my DW788:
Intarsia Wall Art (Multiple Wood Species)
Result: Very good. The Delta’s smooth low-speed operation shined here. Cutting small, irregular pieces from different hardwoods requires patience and control, and the Delta delivered. Final fit was tight and required minimal sanding.
Wooden Puzzle (1/4-inch Baltic Birch, Interlocking Pieces)
Result: Good. Tight internal curves were manageable, though I broke two blades on sharp direction changes—more than I typically break on the DW788. The finished puzzle looked professional.
Decorative Fretwork Panel (1/2-inch Cherry, Intricate Pattern)
Result: Acceptable. The vibration became noticeable on long cutting sessions. I completed the panel, but my hands were more fatigued than usual. Edge quality was slightly less crisp than the DW788 equivalent.
Stack-Cut Ornaments (1/8-inch Walnut, 4 Layers)
Result: Good. The cast-iron base provided enough stability for clean stack cutting. Results were nearly indistinguishable from the DW788.
Custom Signage (3/4-inch Pine, Script Lettering)
Result: Very good. The motor handled thick softwood easily, and the tool-free blade changes made switching between roughing and detail blades tolerable.
Delta 40-694 Pros and Cons: The Full Picture
✅ What I Liked
- 20-inch throat handles large workpieces and wide patterns
- Solid cast-iron base provides stability and reduces vibration
- Tool-free blade changes (once you get the hang of them)
- Smooth variable speed from 400–1,750 SPM
- Better-than-average dust blower with adjustable nozzle
- Included work light is functional if not exceptional
- Strong motor that doesn’t bog down on thick stock
- Competitive price when found on sale
❌ What I Didn’t Like
- More vibration than the DeWalt DW788 due to single pivot arm design
- Blade clamp system is finicky compared to the DW788’s effortless design
- Paint and finish quality is thinner and chips more easily
- Angle scale wears off with use
- Customer support concerns — Delta’s brand has changed hands multiple times
- My unit developed a bearing noise at month six (more on this below)
- Priced too close to the DW788 to justify the compromises
The Bearing Issue: A Concerning Development
At approximately six months of moderate use (maybe 40–50 hours of cutting time), my Delta 40-694 developed a faint grinding noise from the upper arm area. It started subtle—easy to miss over the sound of cutting—but grew more noticeable over the following weeks.
I contacted Delta customer support, and here’s where things got uncomfortable. Delta Power Equipment Corporation has gone through ownership changes and restructuring in recent years. Getting through to a human took multiple attempts. When I finally did, the representative was helpful but vague about parts availability. They suggested I take the saw to an authorized service center, but the nearest one was 90 miles away.
I ended up opening the upper arm myself and found a slightly dry bearing. A shot of quality bearing lubricant quieted it down, and it’s been fine since. But the experience left me uneasy. If a major component fails in year three, will I be able to get parts? Will Delta still be around in its current form? These questions wouldn’t nag me with DeWalt, which has stable corporate backing and ubiquitous service networks.
For a hobbyist who can do their own maintenance, this is manageable. For someone relying on warranty service, it’s a gamble.
Delta 40-694 vs. Competitors: Where It Fits
Delta 40-694 vs. DeWalt DW788
This is the comparison that matters most, and the Delta comes up short. The DW788’s parallel-link arm delivers measurably less vibration. Its blade changes are faster and more intuitive. Its fit and finish feel more refined. And DeWalt’s support network is more reliable.
The Delta’s advantages? A slightly better dust blower, an included work light, and occasionally lower sale prices. For me, those don’t outweigh the DW788’s smoother operation and peace of mind.
Winner: DeWalt DW788
Delta 40-694 vs. WEN 3921
No contest. The Delta is heavier, smoother, more powerful, and better built in every dimension. The WEN is a budget starter saw; the Delta is a serious tool. If you can afford the Delta, skip the WEN.
Winner: Delta 40-694
Delta 40-694 vs. Excalibur EX-21
The Excalibur is a step up in price and performance. Its tilt-head design (instead of tilting the table) is genuinely useful for large workpieces, and the build quality is a notch above. But at $800+, the Excalibur targets a different buyer. The Delta offers reasonable value for those who can’t stretch that far.
Winner: Excalibur EX-21 (if budget allows)
Who Should Buy the Delta 40-694?
Buy the Delta 40-694 if:
- You find it on sale for under $400
- You want a 20-inch throat and tool-free blade changes without paying DeWalt prices
- You do mostly moderate-detail work rather than ultra-fine fretwork
- You’re comfortable doing your own maintenance and minor repairs
- You prefer the included work light and better dust blower over the DW788’s smoother operation
- You already own other Delta tools and want brand consistency
Skip the Delta 40-694 if:
- You can afford the DeWalt DW788 at regular price — the extra $50–$100 is worth it
- You do intricate, vibration-sensitive work regularly
- You rely on robust warranty and customer support
- You change blades constantly and value the fastest possible swaps
- You want a buy-it-for-life tool with guaranteed long-term parts availability
Delta 40-694 Accessories and Upgrades
If you buy this saw, consider adding:
- Quality plain-end blades — Flying Dutchman, Olson, or Pegas. The included blades are mediocre.
- A better work light — The included LED flickered on me after a few months.
- Bearing lubricant — Keep those arm bearings happy. I use a light machine oil monthly now.
- A heavy stand or bench — The 55-pound base helps, but a solid mounting surface still matters.
- Shop vac or dust collector — Even the decent blower needs backup for thick cuts.
Final Thoughts: The Middle Child Syndrome
The Delta 40-694 reminds me of a talented athlete who never quite made the starting lineup. It’s capable, well-equipped, and performs adequately in most situations. But it lives in the shadow of the DeWalt DW788, which does everything the Delta does slightly better for a marginally higher price.
If Delta had priced this saw at $350, it would be a no-brainer recommendation for budget-conscious buyers wanting serious capacity. At $500, it asks too much when the DW788 hovers around $550–$600. The vibration, the finicky blade clamps, the quality control concerns, and the bearing issue on my unit all add up to a tool that doesn’t inspire the same confidence as its rival.
That said, I made good work on this saw. The intarsia pieces came out beautiful. The puzzles fit together perfectly. The signs sold at craft fairs. The Delta didn’t hold me back from creating—it just made the process slightly less enjoyable than my DW788.
If you find a Delta 40-694 for $380 like I did, grab it. It’s a steal at that price. But at full retail, do yourself a favor and save for the DeWalt. Your hands, your ears, and your future self will thank you.
