Best 12-inch sliding miter saw

DeWalt DWS780

DeWalt's 12-inch compound miter saws top the list

Owners say the biggest drawback of a 10-inch chop saw is its small capacity. However, if you only need to cut an occasional oversized board, it's not necessarily worth shelling out $400 or more for a sliding miter saw. For owners in this position, a 12-inch compound miter saw is a good compromise. In the Journal of Light Construction, Andy Beasley explains, "Sliding miter saws are more versatile, but they're expensive and bulky. If you can get by without the wide horizontal cutting capacity afforded by a slider, a 12-inch chop saw can save you a pile of money."

With one of the largest capacities of a non-sliding saw, the DeWalt DW715 (Est. $220) can chop up to 6.5-inch baseboard placed vertically against the fence. Like the smaller DeWalt DW713 (Est. $220) (described in our discussion of the best 10-inch compound miter saws), this 15-amp, single-bevel saw can make mitered cuts of up to 50 degrees in either direction and beveled cuts of up to 48 degrees. It has three firm bevel stops and 11 miter stops, plus a detent override that lets you lock in a custom angle.

Reviews say the DW715 is accurate right out of the box and delivers first-class performance. In his comparison, Beasley says the DW715 has the best miter lock of the bunch; "(the saw's) cam-style lever is faster and easier to use than the screw knobs that are on the other machines." It also has more vertical capacity and cuts more smoothly than any other saw. Owners at Amazon.com and Lowes.com describe the DW715 as durable, accurate, and easy to adjust. Users' main complaint is that, like the DW713, this saw comes in multiple versions, some of which do not work with DeWalt's optional laser or LED work light. Dust collection is also unimpressive, though no worse than on most other saws.

Users who need to make a lot of compound cuts will save time with a dual-bevel miter saw, which can tilt the saw head in two directions. The DeWalt DW716XPS (Est. $360) has the same convenient features and accurate performance as the DW715 and can bevel left or right. "Although pricey, it cuts superbly, operates easily, boasts the greatest cutting capacity, and is easy to carry," says Beasley, who tests both DeWalts in his review. Users at Amazon.com give the DW716XPS slightly higher marks than the DW715, mostly because of its built-in XPS system: an LED work light that also serves as a cutting guide. Owners say it's worth paying an extra $15 or so for the DW716XPS rather than the DeWalt DW716 (Est. $350), which, though otherwise identical, does not include the LED light and it can't be added on.

Both the DW715 and the DW716XPS include DeWalt's three-year warranty, a one-year free service contract and a 90-day money-back guarantee. Users need only consider whether the dual-bevel convenience and the XPS system are worth the extra cost.

12-inch sliding compound miter saws have the biggest cutting capacity

Stepping up to the larger cut capacity of a 12-inch sliding compound miter saw means a jump in overall size, weight and price as well. However, it can be a worthwhile investment for serious woodworkers and professional craftsmen. We didn't find any professional comparison reviews for this type of saw, but there are several single-product reviews available on the Tools in Action website, as well as plenty of feedback on retail sites like Amazon.com and Lowes.com.

Out of all these reviews, we found the strongest feedback for the 12-inch sliding DeWalt DWS780 (Est. $600). This giant dual-bevel saw can cut baseboard molding up to 6.75 inches in size vertically against the fence (or up to 7.5 inches of nested crown molding), as well as making 45-degree bevel cuts in lumber up to 2x16 at 90 degrees and 2x12 at 45 degrees. It can make mitered cuts up to 60 degrees to the right and 50 degrees to the left and can bevel up to 45 degrees in either direction. Dan Maxey of Tools in Action says this saw offers "dead on" "accuracy, combined with power and a sturdy build.

One feature both professionals and homeowners love about this sliding miter saw is its built-in LED light system, which casts light on both sides of the blade so you can use its shadow to trace the path of your cut. Reviewers also say the saw is well balanced, easy to adjust, and surprisingly quiet. They disagree about dust collection, however. While Maxey says the system "works great at capturing most of the dust," users tend to complain that the small dust collector bag is useless. Attaching a vacuum to the dust collection tube works somewhat better, but some owners note that the tube is too narrow and can become choked with sawdust. They also find the built-in clamp hard to adjust. A final problem noted in many Amazon.com reviews is that the sliding mechanism is very rough and sticky, especially on first use. However, some owners say the motion gets smoother over time, especially with the aid of a little machine oil. DeWalt backs this saw with the same 90-day/one-year/three-year warranty offered on its chop saws.

Feedback is also good, though not as uniformly positive, for the Bosch GCM12SD (Est. $620). Unlike most sliding miter saws, which glide along rails, the Bosch has a complex articulated arm that moves the saw head back and forth. Eric Jopp of Tools in Action says this design saves you as much as 12 inches of workbench space, and the head provides "consistent precision cutting" with "one heck of a smooth glide." For those who don't like the motion to be quite that free-flowing, Jopp notes that the tension on the arm can be adjusted to make it stiffer.

The Bosch has a miter angle range of 60 degrees to the right and 52 degrees to the left – just a hair more than the DeWalt – and its bevel range is 48 degrees on either side. It can cut boards up to 14 inches wide laid flat and 6.5 inches standing upright. Users also says it's powerful, easy to adjust, and very solidly built. Its biggest drawbacks are price and weight. At 65 pounds, this saw is the heaviest we've seen, as well as the most expensive. We also saw complaints about the hefty saw being damaged during shipping, often in ways that impair its accuracy. So unless you really need those extra few inches of benchtop space, we see no compelling reason to choose this Bosch saw over the DeWalt.
