This comparison is as much about the cordless-versus-corded question as it is about these two specific saws. The Bosch GTS18V-08N is an 18V cordless table saw that costs more than the DeWalt DWE7491RS — a 10-inch corded contractor saw that has been a jobsite standard for a decade. You are paying more for the cordless Bosch to get less blade size and less sustained cutting power. The question is whether the cord elimination justifies that trade-off for your specific work, and the honest answer is: only sometimes.

Specs Comparison

The Fundamental Trade-Off: Blade Size and Power

The DeWalt DWE7491RS uses a 10-inch blade running at 4,800 RPM from a 15-amp motor — the same power specification as most professional contractor table saws. A 10-inch blade provides 3-1/8-inch cutting depth at 90 degrees, enough for 3x dimensional lumber and full ripping of 3/4-inch sheet goods in a single pass. The 32-1/2-inch rip capacity on the DWE7491RS handles a full 4x8 sheet ripped to 24-1/2 inches without moving the fence or repositioning the stock.

The Bosch GTS18V-08N uses an 8-1/4-inch blade running on 18V PROFACTOR lithium batteries. The 8-1/4-inch format limits cutting depth to 2-1/2 inches at 90 degrees — which means doubled 2x4 assemblies are at the limit, not the center of the capability. Rip capacity is 24-1/2 inches — adequate for most sheet goods work but achieved only at the blade size limitation.

The corded motor has no runtime constraint. On a busy cabinet shop day cutting 50 sheets of 3/4-inch plywood, the DWE7491RS doesn't slow down, doesn't need battery swaps, and doesn't throttle under sustained load. The Bosch GTS18V-08N on a pair of PROFACTOR 8.0Ah packs gets approximately 60-70 ripping cuts per charge in 3/4-inch plywood — meaningful for site work, limiting for production.

When Cordless Actually Wins

The Bosch GTS18V-08N earns its place in specific scenarios where a cord creates a genuine constraint. Finish work on upper floors of a building under construction, where running an extension cord up two flights while managing material and saw weight creates actual friction. Renovation work in older buildings without accessible 20-amp circuits — the GTS18V-08N doesn't require one. Remote job sites without power access where a generator adds cost and noise.

In these situations the cordless premium ($399-449 vs the DWE7491RS's $499-599 with stand — actually comparable) buys real workflow freedom that translates to time savings on the job. The math changes when cord management is genuinely expensive or impossible.

For a permanent shop setup, a weekend woodworker's garage, or any application with reliable power access: the DWE7491RS's 10-inch blade, 15-amp motor, and rolling stand with 32-1/2-inch rip capacity make it the better tool without qualification.

Fence Quality, Rolling Stand, and Accuracy

The DeWalt DWE7491RS ships with a rolling stand — one of the better mobile contractor saw stands available as an included accessory. The rack-and-pinion telescoping fence with front-and-rear locking is accurate to within 1/32-inch over 32 inches with proper calibration. For a contractor saw at this price, the fence quality is genuinely good.

The Bosch GTS18V-08N's fence system is adequate but receives mixed field feedback on consistency over time. The smaller saw body means a shorter fence rail, which limits accuracy-over-distance. For precision furniture-grade work, the DWE7491RS's fence setup is more reliable.

The Bosch doesn't include a stand — it's designed to be set up on a workbench or job box. Add a stand and the price approaches the DWE7491RS with rolling stand. Factor this into your all-in cost comparison.

Price, Platform, and Honest Advice

The DeWalt DWE7491RS with rolling stand runs $499-579 — a complete, production-capable setup including stand. The Bosch GTS18V-08N tool-only runs $349-399, but requires Bosch PROFACTOR 18V batteries ($129-179 each for 8.0Ah packs) that are separate from Bosch's standard 12V and 18V Bluetooth lines. All-in with two batteries and a charger, the Bosch costs $607-757 — more than the corded DeWalt with stand.

The Bosch PROFACTOR platform is separate from Bosch's standard Professional 18V (PS/GSR) line — the batteries are not cross-compatible. This is a critical purchasing detail: if you own Bosch 18V PROFACTOR tools (which use the same Starlock battery interface), the GTS18V-08N adds to an existing investment. If you don't own any PROFACTOR tools, you're starting a new battery platform for one tool.

The honest summary: buy the DWE7491RS if you have reliable power access at your primary work location. Buy the GTS18V-08N only if cordless access is a genuine daily constraint — and factor the PROFACTOR battery investment into your real cost. The cordless premium has a legitimate use case; it's just smaller than the marketing suggests.

Best For

• Bosch GTS18V-08N (18V Cordless) Finish carpenters and site workers who genuinely lack reliable power access and already own PROFACTOR batteries
• DeWalt DWE7491RS (Corded 10-in) Any contractor with regular power access who wants a production-capable 10-inch jobsite saw that doesn't require platform investment
