A battery pack connection system includes a first battery pack, a second battery pack, and a battery receptacle. Each of the first and second battery packs includes a first guide slot, a second guide slot, and an electrical connector slot. The second battery pack has a power capacity and a width greater than the first battery pack. The battery receptacle defines an elongate passage sized and shaped to separately receive each of the first and second battery packs therein. The battery receptacle includes an electrical connector rail, a first guide rail sized and shaped to cooperatively engage the first guide slot of each of the first and second battery packs, and a second guide rail sized and shaped to cooperatively engage the second guide slot of each of the first and second battery packs.

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.

A battery pack includes a housing, at least one battery cell enclosed within the housing, a printed circuit board (PCBA) enclosed within the housing, a gauge electrically connected to the PCBA and including at least one light, and an actuator that, when actuated, activates the gauge to illuminate the at least one light to indicate a charge level of the at least one battery cell. The housing has a main body and a handle extending from the main body, and the handle defines an aperture sized and shaped to receive one or more of a user's fingers therein. The gauge is located on an outer surface of the handle.

Systems for cutting cylindrical workpieces such as pipe are described. The systems include a clamping assembly and can be used in various methods. In one method, the clamping assembly and a cutting tool or saw is used on a rotating workpiece. In another method, the clamping assembly and a cutting tool or saw is used on a stationary workpiece. Also described are frames that can be secured to the clamping assembly.

Power drive tools are described. The tools include one or more threading pawls, one or more release pawls, and a drive ring selectively positionable relative to the tool and engaged with the pawls to selectively extend or retract the pawls. Also described are tools that include one or more lights to illuminate a workpiece. Also described are tools having distally located shoulder regions at which force may readily be applied. In addition, gear train assemblies for use in the power drive tools are described.

Pipe threading mechanisms and systems

Various methods are described for forming threads in a workpiece, and particularly for controlling and/or monitoring threading of workpieces. Also described are tools and a system used in performing the methods.

Algorithms and methods for controlling threading of pipe

A high output lamp is made with LED filaments (i.e., LED chips mounted on a long narrow substrate and encapsulated in silicone). High output is enabled by structurally minimizing thermal resistance between filaments and bulb. The bulb is generally tubular and contains a mount structure with longitudinally extended LED filaments electrically and mechanically connected between ring or disc shaped end connectors, and spaced apart around the structure's perimeter. An outer surface of the LED filaments defines a mount structure perimeter that is held adjacent to an inner surface of the bulb, separated by a total diameter difference gap of substantially zero to three millimeters maximum. End connectors may have a cut out portion enabling resiliently compressible diameter. The bulb may be filled with pure helium, or pure hydrogen, or a mixture of the two. A contaminant cleaner inside the bulb may be an oxygen dispenser.
