A Buyer S Guide To Sliding Compound Miter Saws

What is a Sliding Compound-Miter Saw?

Sliding compound-miter saws will work just like chop saws, but because their blades move back and forth on horizontal rails, they also can slice stock up to 15 inches wide in one stroke. In the years since Hitachi first introduced theirs in 1988, these sliding-head saws have undergone numerous refinements and upgrades, and now, with the availability of cordless versions, they’re even more useful for home-remodeling projects. Here’s the latest on this special class of tools.

Types of Miter Saws to Consider

Most Portable

Compact (71/4-, 71/2-, or 81/2-inch blades)

The takeaway: Relatively lightweight and easy to carry, these saws don’t need a lot of working room and don’t take up a lot of storage space. They’ll cut boards up to a 2×8, but their vertical cutting capacity is limited: They can’t cut most crown when nested (see p. 101) or baseboards standing on edge. Blade options are also limited, and there are fewer cordless offerings. With motor power typically in the 10- to 12-amp range, they can bog down in dense or wet wood.

Most Versatile

10-inch

The takeaway: Their larger blades allow you to crosscut stock up to a 2×12, and have enough vertical capacity to cut common trim sizes, both standing up and nested, or to slice through a 4×4 in one pass. Cutting power isn’t a problem; even a pressure-treated post won’t slow them down. A wide selection of models are available in this size, including cordless options, along with different blade styles and price points. But a bigger size means extra weight and a bigger footprint; they’re best used on a stand or benchtop. Shown: Milwaukee M18 Fuel Dual-Bevel Sliding Compound Miter Saw R4210

Pack Lots of Power

12-inch

The takeaway: These saws offer the largest cutting capacity, both vertically and horizontally; they can saw through a 6×6 in one pass, and just about any crown (in a nested position) or base molding (stood on edge). They’re also the most powerful saws of the bunch, and the most expensive. Park them on a bench and leave them there; they’re heavy and difficult to carry. There aren’t many cordless options in this size, as of yet. Shown: Makita Dual-Bevel Sliding Compound Miter Saw LS 1219L
