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.

The present disclosure relates to a cutter clamp (8, 37) that comprises a first arm part (10, 39) and a second arm part (11, 40), where the arm parts (10, 11; 39, 40) are arcuate and arranged to adjustably at least partially enclose a major part of a circumference (57, 63) having a center (58, 64). The cutter clamp (8, 37) comprises at least one hollow rod (21, 22; 48, 62) arranged for receiving a mounting rod (36) for a power cutter (1, 56) in a pivoting manner. The smaller circumference the arm parts (10, 11; 39, 40) are adjusted for, the closer to the center (58, 64) said hollow rod (21, 22; 48, 62) is moved. The present disclosure also relates to a cutter clamp attachment device (68), a cutter clamp kit and a cutter clamp holding frame (76).

Power tools such as cutting saws with rotary powered blades are described. Also described are various accessories for tools used with cylindrical workpieces such as pipes are described. The accessories include a clamp and saw joint assembly, various quick connection assemblies between a saw and a clamping system, a plunge guide assembly, a latch plate assembly, an interlock switch, a blade guard system, and a chip management system or chip deflector. Also described are related methods of use.

An attachable and extendable saw and methods for cutting an object on a work surface with the attachable and extendable saw are provided. The extendable saw can include a saw blade housing coupled to a main body by at least one extendable member, the saw blade housing at least partially covers a saw blade and the extendable member can be configured to move the saw blade housing and the saw blade between a retracted position and an extended position relative to the main body. The extendable saw can also include a motorized unit coupled to the saw blade and configured to rotate or provide other blade movement to the saw blade and a switchable device or unit disposed on the main body and having at least one contact surface that facilitates attachment of the extendable saw to the work surface, said contact surface being switchable between a magnetized or vacuum state and a non-magnetized state or non-vacuum state, respectively. Attachment of the saw blade to the attachable and extendable saw is provided for.

An attachable and extendable saw and methods for cutting objects with the attachable and extendable saw are provided. The attachable and extendable saw can include a blade housing coupled to a main body. The blade housing at least partially covers a saw blade and the extendable member can be configured to move the saw blade with or without the blade housing between a retracted position and an extended position relative to the main body. The extendable saw can also include means to drive the saw blade, means to drive the extendable member, and means for attaching the attachable and extendable saw to the objects to be cut. Saw blade height adjustment means, handles for ease of use, and eyelets for tethering are provided. The saw blade is attached to the attachable and extendable saw via pins and fasteners.

A portable saw assembly for use in making square cuts in metal structural components. The portable saw assembly includes a clamping system to hold a work piece in a fixed position with respect to the rotating saw blade and the saw blade is constrained for movement toward and away from the work piece along a specific prescribed path that assures that the saw blade will encounter and then cut the work piece at a right angle with respect to the longitudinal axis of the work piece. Thus, the portable saw assembly can be located on site of the construction and yet can be readily and easily used to cut the structural component along a square cut to facilitate the assembly of the ultimate structure. The clamping system includes clamping inserts to accommodate different sizes and geometric shapes of work pieces while still assuring a square cut thereof.
