Lots of capacity, but at a cost.
Prized by carpenters for its amazing versatility, a sliding compound miter saw is also great to have in a woodworking shop. The blade swivels for miter cuts and the head tilts for bevel cuts. To make compound miter cuts, you simply swivel the blade and tilt the head. Compared with a nonsliding compound miter saw, the big difference is capacity: A typical sliding saw easily cuts 12-in.-wide boards. That’s 3 to 4 in. wider than the largest nonsliders can cut.
A sliding compound miter saw easily makes cuts that are difficult on a tablesaw. For example, accurately mitering the end of a long, wide board on your tablesaw is virtually impossible, because the miter gauge is too small and the saw table isn’t big enough to support the angled board during the cut. With a sliding miter saw, just position the board, swivel the blade, line up the laser guide and go. Switching from crosscutting big timbers to cutting compound miters in delicate trim takes only seconds. Making 60-degree cuts for an equilateral triangle is simple and cutting exotic compound miters for complex assemblies is no sweat.
Sliding miter saws are available in many sizes, which are determined by blade diameter. We tested 12-in. saws because they have the largest capacity and are available in the widest variety of models. We also compared different sizes of saws (see “Choosing a Sliding Compound Miter Saw,”).
Digital Display
What looks like an alien eyeball on top of an insect’s body is actually a welcome step by Hitachi toward precision woodworking: a digital display of miter and bevel angles. |
Maximum Capacity Has a Price
The Ridgid and DeWalt saws feature the largest crosscut capacity, 1 in. to 1-1/2-in. more than any other saw we tested. (The DeWalt crosscuts up to 16 in. with modifications). Both saws achieved this, in part, by dropping the blade deep into the bed of the saw so it cuts closer to its full diameter. The downside of this design is that during a sliding cut, the teeth on the blade’s back edge rotate directly up into the board. If the board isn’t firmly clamped in place, especially during wide compound miter and bevel cuts, the blade can violently kick it up. Owner’s manuals for both these saws strongly urge using the hold-downs for all cuts. We second that. |
The $180 Sliding Compound Miter Saw: In a Class by ItselfIntrigued by its astonishingly low price, we also tested the 12-in. Chicago Electric 91852-2VGA saw. Although this saw isn’t engineered as precisely or built as heavily as the expensive saws, it still makes most of the cuts they make, just not as easily or as accurately. If you only want to construct a deck, frame the basement or do rough crosscutting, the price—one-third the cost of the other saws we tested—makes this saw a real contender. |
Makita-LS1214F- $600
|
Bosch-5412L, $650
This saw has many user-friendly features.
Pros– Front-mounted bevel controls are – Bevel scale is large and readable. – Quick-release hold-down is tenacious. – Built-in extension wings are perfectly level with the saw bed. – Handle adjusts to horizontal, vertical and diagonal (45-degree) positions. – We liked the viewing slot in the blade guard; some editors preferred it over the laser for lining up cuts.
Cons– The factory-supplied blade required – Hold-down isn’t particularly user-friendly. – Dust collection is average. – Saw requires a lot of space. |
Craftsman-21206, $600
This saw appears similar to the Bosch 5412L, especially regarding several user-friendly features.
Pros– Front bevel controls on this saw are – Bevel scale’s readablity is above-average. – We liked the quick-lock lever for setting miter angles. – Handle adjusts to horizontal and
Cons– Cut quality is average. – Blade guard catches on 45-degree – Built-in extension wings sit below the saw bed. – Bevel range is limited to 45 degrees. – Dust collection is average. |
DeWalt-DW718, $660
If you need big cutting capacity, this is an excellent choice.
Pros– Removing the main fence and adding a 1-1/2-in.-thick subbase increases crosscut capacity to 16 in. and miter capacity to 11-5/8 in. – We like this saw’s unique, simple system for truing the miter settings: Instead of aligning the fence with the saw blade, you loosen a few Allen nuts and shift the saw bed into alignment with the fence. – This saw is light in weight and very compact. – We like the front-mounted laser,
Cons– Blade makes rough, splintery cuts. – Saw head jumps on start-up more than any other tested saw, so can drop down and nick a board if you’re not prepared. – Dust collection is average. – Hold-down is difficult to securely tighten. |
Hitach-C12LSH, $650
|
Metabo-KGS305, $650
This saw has minimal side-to-side play and
Pros– Widely spaced rails minimize its side-to-side play. – Dust collection is better than average. – Quick-release hold-down is effective; an adjustable arm extends its reach by 1-1/2 in. – Has a wide bevel range.
Cons– The factory-supplied blade cut smoothly, but left slightly curved faces. However, with the Makita blade installed, this saw cut straight and true. – Requires a lot of space. – Awkwardly placed bevel lock doesn’t work well enough. It’s finicky to adjust; we never got it to securely lock the saw head without being impossible to operate. – Right-tilt bevels are hard to set accurately because you can’t see the scale when you reach around and under to lock the saw head. – Built-in extension wings sag below the saw bed. – Bevel scale is tiny; the bubble-style plastic indicators were difficult to read. |
Ridgid-MS1290LZ, $570
This saw features large capacities, big,
Pros– Has the widest miter range, second-widest bevel range and second-widest crosscut capacity. – Has the biggest bevel scale. – Locking miter handle and detent release are combined into a smooth, user-friendly control. – Bevel lock is convenient and easy to use. – Cam wheel design makes blade-depth adjustments easy.
Cons– Dust collection is average. – Quick-release hold-down was difficult to securely tighten. – Bubble-style bevel-scale indicator traps sawdust, making it hard to read. (We had to remove the indicator to clean it.) – Bed is smaller than most, only 10-1/2 in. from the blade to the edge, and extension supports aren’t available. – Requires a lot of space. |
