A miter saw has a base assembly and a rotatable table disposed on the base assembly. The rotatable table is rotatable about a substantially vertical miter axis and has a substantially horizontal workpiece-supporting plane. A saw assembly is connected to the table and includes a blade. The blade is movable downwardly from a first position where the blade is above the workpiece-supporting plane to a second position where a portion of the blade is below the workpiece-supporting plane. The base assembly has a top surface and a first handle disposed on the top surface, with a first hole on the top surface extending through the base assembly, the first hole being configured to allow a user to extend the user's hand therethrough and grip the first handle.

A cold saw module may be a rail saw module that includes a cold saw configured to cut a railway rail along a cutting path, a rail alignment clamp configured to grip the railway rail near the cutting path, a feed actuator to drive the cold saw along the cutting path, and a module coupling element configured to selectively couple to a mating module coupling element of an articulated arm and/or a tool adapter. Cold saw modules may be used to cut metal workpieces such as a railway rail. Cutting a railway rail may include positioning the cold saw module at a cutting site along the railway rail installed in a railway, clamping the cold saw module to the railway rail, and cutting the railway rail at the cutting site with the cold saw module while the cold saw module is clamped to the cutting site.

An apparatus for cutting a window covering comprises a saw for cutting the window blind. A clamp assembly moves the window covering relative to the saw. A controller moves the clamp assembly to automatically position an end of the window covering relative to the saw. The saw is moved into engagement with the window covering to cut the window covering. A dust collection system comprises a shroud substantially surrounds the bottom of the saw blade where the shroud is connected to a vortex dust collector.
