A cutting belt comprises a guide bar system that includes a guide bar. The guide bar has a first end section, a second end section, and a central section between the first end section and the second end section. A first upper fluid channel is defined through the guide bar. The first upper fluid channel has an entrance opening in the first end section of the guide bar and extends to the central section of the guide bar where it is in fluid communication with a bottom channel. The second upper fluid channel has an entrance opening in the second end section of the guide bar and extends to the central section of the guide bar where it is in fluid communication with the bottom channel.

A handheld band saw includes a housing assembly including a battery pack mounting portion for mounting a battery pack, a rotating wheel assembly at least partially disposed in the housing assembly and including a first rotating wheel and a second rotating wheel, where the first rotating wheel and the second rotating wheel are configured to be substantially symmetrical about a midplane, an electric motor disposed in the housing assembly and capable of driving one of the first rotating wheel and the second rotating wheel to rotate, a fan which is capable of generating at least one airflow in the housing assembly, and a control circuit board disposed in the housing assembly.

Embodiments of the innovation relate to a blade angle adjustment assembly, comprising a blade angle adjustment mechanism; a tooth load indicator; and a blade angle controller disposed in electrical communication with the blade angle adjustment mechanism and with the tooth load indicator. The blade angle controller is configured to receive a tooth load indication signal from the tooth load indicator and, the tooth load indication signal, provide a drive signal to the blade angle adjustment mechanism to adjust an angular positon of a bandsaw blade within a cut plane of a workpiece.

A band saw includes a first blade guide assembly and a second blade guide assembly which guide the band saw blade through a cutting zone. The first blade guide assembly and the second blade guide assembly are each supported for pivotal movement about a pivot axis between a first angular position and a second angular position. At the first angular position, the first and the second blade guide assemblies hold the band saw blade at a first angle with respect to the wheel contact plane. At the second angular position, the first and the second blade guide assemblies hold the band saw blade at a second angle with respect to the wheel contact plane, the second angle being different than the first angle.

A guide insert for a saw blade guide for guiding a saw blade, including at least two blade guiding elements held in the guide insert, at least one pair of side blade guiding elements disposed in parallel and at the same height being accommodated in the guide insert, a slot for laterally guiding the saw blade being formed between a first side blade guiding element and a second side blade guiding element in a use position, the blade guiding elements having a rotationally symmetrical shape with respect to an axis of symmetry, including a cylindrical friction surface, the blade guiding elements each being held clamped in a cylindrical recess of the guide insert in a force-fitting and/or form-fitting manner via a loosenable clamp in the use position, and the blade guiding elements being able to be placed from a first rotational position into other rotational positions.

A band saw kit including a band saw and an angle guide. The band saw includes at least one wheel for supporting a saw blade, a motor operable to drive the blade to cut a workpiece, a frame, and a workpiece bumper coupled to the frame. The workpiece bumper includes a slot configured to receive the blade, a first engaging surface defining a first plane, and is configured to be generally perpendicular to the blade as the blade passes through the slot. An angle guide is configured to be coupled to the workpiece bumper and includes a second engaging surface for engaging a workpiece. The second engaging surface defines a second plane. A cut angle is defined by an angle between the second plane and the first plane when the angle guide is coupled to the workpiece bumper.

A sample cutting assembly includes a base block, a saw pressure plate, an external blade guide, and an internal blade guide. The cutter can be used to conveniently remove samples for Material testing to determine serviceability or material condition. Apparatuses and techniques for using the sample cutting assembly are also disclosed.

A band saw vice assembly for securing a substrate for cutting includes a base that has a first plate coupled to and extending vertically from a first side. A first bar, which is hollow, is coupled to and extends perpendicularly from the first plate. A second plate is coupled to and extends perpendicularly from a sleeve that is positioned around the first bar. A first slot and a second slot, which are aligned and perpendicular to the base, are positioned in the first plate and the second plate, respectively. An actuator, which is operationally coupled to the sleeve, is coupled to and positioned in the first bar. The actuator is positioned to motivate the second plate toward the first plate to frictionally couple to a substrate to fixedly position the substrate. The first and second slots are configured to insert a blade of a band saw to cut the substrate.

Provided are a porous media bearing for a band saw, a band saw for cutting cant and a method of cutting cant using the band saw. The band saw has a continuous loop blade supported by a drive wheel and first and second support arms having porous media bearings. A location of a blade cutting section, an angle of the blade in relation to the cant being cut, and tension on the blade can be adjusted by moving the first and second support arms.

A band saw for sawing a rail of a track is configured for fastening to a vice which can be clamped onto the rail and is provided with a feed device. The band saw includes a frame in which four saw band rollers are mounted. A saw band is stretched around the four saw band rollers and, in a recess of the frame, the saw band is twisted into a sawing plane by guiding elements. Due to the utilization of four saw band rollers, there is little wear of the saw band, resulting in a longer service life.
