Our verdict

A strong choice for trim and framing work that needs double bevel capacity and wide crosscuts, at the cost of being a larger, heavier saw than compact 10-inch alternatives.

ASIN: B01ESCU5WSModel: DWS779Category: Miter Saws

Overview

A 12-inch double bevel sliding compound miter saw powered by a 15 amp, 3,800 RPM motor, built for crosscutting dimensional lumber and trim work with dual bevel angles up to 49 degrees in each direction.

The DWS779 is aimed at trim carpentry as much as general framing: its tall sliding fences support crown molding up to 7-1/2 inches nested and base molding up to 6-3/4 inches vertically, and they slide out of the way for bevel cuts. Dual horizontal steel rails and linear ball bearings are what let the saw slide smoothly for the wider crosscuts a 12-inch blade allows.

  • 12-inch double bevel sliding compound miter saw
  • 15 amp, 3,800 RPM motor
  • Miters 60 right / 50 left, bevels 49 both ways
  • Tall sliding fences fit crown molding to 7-1/2 in

Who it's for

Suits finish carpenters and serious DIYers cutting crown molding, base molding, or larger dimensional lumber who need both left and right bevel without flipping material. It is heavier and larger than a compact 10-inch saw, so it suits a shop or job trailer more than tight, portable use.

Pros and cons

Pros
  • Double bevel up to 49 degrees each direction, no flipping stock
  • Tall sliding fences fit crown and base molding
  • 10 positive miter stops for repeatable angles
  • Dust collection captures over 75 percent of debris
Cons
  • Larger and heavier than compact 10-inch miter saws
  • Sliding rail design needs more bench or floor depth

Performance notes

The dual horizontal steel rail system with linear ball bearings lets the saw head slide forward and back for crosscuts up to 2x14 lumber at 90 degrees and 2x10 at 45 degrees. The cam lock miter handle with detent override, plus a stainless steel miter detent plate with 10 positive stops, are what keep repeat miter angles accurate, and the dust collection system is rated to capture over 75 percent of generated dust.
