Quick Answer
If you mostly cut mild steel up to about 4-3/4 inches and want the cheaper evolution chop saw, the EVOSAW355 does the job. If you regularly cut larger profiles, work through higher daily volume, or want the bigger 15-inch blade and heavier base, the S380CPS is the one to buy. Both are dry-cut saws designed to replace abrasive chop saws, and both use Evolution’s tungsten-carbide-tipped blades instead of grit wheels.
How a Dry-Cut Chop Saw Differs from an Abrasive Saw
Traditional abrasive chop saws grind through metal at high RPM, throwing sparks, heat, and dust everywhere. An evolution chop saw spins a carbide-tipped blade at roughly 1,450–1,550 RPM — much slower — and shears chips off the steel instead of burning through it. The result is a cool-to-the-touch cut, almost no sparks, a finished edge that often needs no deburring, and a blade that lasts far longer than a $4 abrasive wheel.

The trade-off is blade cost: a replacement 14-inch Evolution steel blade runs in the $80–$110 range versus a few dollars for an abrasive wheel. But one carbide blade typically outlasts 20 or more abrasive wheels on mild steel, so the cost per cut still favors the dry-cut saw for anyone cutting metal weekly.
EVOSAW355 vs S380CPS: Spec Comparison
| Spec | EVOSAW355 | S380CPS |
|---|---|---|
| Blade diameter | 14 in (355 mm) | 15 in (380 mm) |
| Motor | 15 A, ~1,800 W | 15 A, ~1,800 W |
| No-load speed | ~1,450 RPM | ~1,550 RPM |
| Max square tube (mild steel) | ~4-3/4 in | ~4-3/4 in |
| Max rectangle (mild steel) | ~3-3/4 x 7-1/8 in | ~3-3/4 x 7-1/8 in |
| Max round tube | ~5-1/8 in | ~5-1/8 in |
| Angle iron | ~4-3/4 in | ~4-3/4 in |
| Miter range | 0–45° | 0–45° |
| Weight | ~53 lbs | ~62 lbs |
| Typical street price | $300–$400 | $450–$550 |
On paper the capacities look nearly identical — and they are, for standard profiles. The real differences show up in blade diameter (which affects gullets-per-cut and blade life on thick stock), the heavier cast base on the S380CPS, and a motor that holds speed better through repeated heavy cuts.
Where the EVOSAW355 Wins
The EVOSAW355 is the right evolution chop saw for most fabricators, hobby welders, and contractors cutting tube, angle, channel, and flat bar:
- Price gap is real money. At roughly $100–$150 less, the savings nearly covers a spare blade.
- Lighter to move. At about 53 lbs it’s still a two-hand lift, but manageable for a saw that goes between the truck and the bench.
- Blades are cheaper and everywhere. 14-inch Evolution blades (steel, aluminum, stainless, and multi-material variants) are the most widely stocked size in the lineup.
- Capacity covers 90% of jobs. 2×2 and 3×3 tube, 4-inch angle, and schedule-40 pipe up to about 4 inches all fit fine.
When the Bigger S380CPS Pays Off
- High daily volume. The heavier base, larger blade mass, and motor tuning keep cut quality consistent across dozens of cuts a day. In a fab shop cutting steel all morning, that stability matters.
- Thicker solid stock. The 15-inch blade runs a slightly higher RPM with more teeth engaged at the periphery, which helps it stay composed through solid bar and thick-wall tube where a 14-inch blade can start to labor near the end of its life.
- Multi-material blades. The S380CPS is commonly sold or paired with Evolution’s multi-material blade, which cuts steel, aluminum, wood with nails, and plastics. If you want one saw that also handles wood studs and aluminum extrusion without blade swaps, the 380 platform is the natural fit.
- Long-term blade economics. A 15-inch blade has more carbide and more sharpening life; per-foot of steel cut, heavy users often come out ahead.
Decision Matrix
| Your situation | Pick | Why |
|---|---|---|
| Weekend fabricator, occasional steel cuts | EVOSAW355 | Capacity is sufficient; save the difference |
| Mobile contractor, saw travels daily | EVOSAW355 | ~9 lbs lighter, same core capacity |
| Fab shop, 20+ cuts a day | S380CPS | Heavier base and blade longevity under load |
| One saw for steel, aluminum, and wood | S380CPS | Best platform for the multi-material blade |
| Cutting mostly solid bar / thick wall tube | S380CPS | More blade engagement, steadier cut |
| Tight budget, first metal-cutting saw | EVOSAW355 | Lowest entry cost into dry-cut cutting |
Blades, Consumables, and Ownership Reality
This is what a product listing won’t tell you. The blade is your ongoing cost, and how you use it determines whether it lasts months or weeks:
- Use the right blade. The mild-steel blade chews itself up fast on stainless — Evolution makes a dedicated stainless blade for a reason. The multi-material blade is a compromise: fine on thin steel and wood, slower on heavy plate.
- Let the saw feed itself. Forcing the cut is the #1 blade killer. Let the carbide do the work; a 2×2 tube in 11-gauge should take roughly 8–12 seconds.
- Clamp everything. The vise must hold stock tight. Vibration chips carbide teeth — chipped teeth mean a $100 blade is done early.
- Clear chips regularly. The chip tray fills fast; packed chips reflect back into the blade path and accelerate wear.
- Blade life reality. Expect roughly 1,000+ cuts in mild steel tube per blade with good technique, far fewer on solid stock. Budget one to three blades a year for regular use.
- What wears first: the blade, then the vise jaw faces, then the spark guard pivot. Brushes in the motor are a normal service item after a few years of shop use.
Verdict
For most buyers, the EVOSAW355 is the better value evolution chop saw — identical real-world capacity at a meaningfully lower price. The S380CPS earns its premium only if you’re a high-volume user, want the multi-material blade flexibility on a bigger platform, or routinely push through solid and thick-wall steel where the larger blade and heavier chassis keep cuts square all day.
