A cutting grinder for cutting through a rail of a track includes a detection device for detecting a proposed cutting position. The cutting grinder guarantees simple, user-friendly and efficient through-cutting of the rail.

The Table Saw Depth Gauge comprises a gauge, slide scale, or ruler, that is positioned onto a table saw so that the depth that the saw blade will cut into a piece of wood, or board, can be measured by the gauge, slide scale, or ruler prior to cutting, allowing a user of the table saw to confirm saw blade depth prior to making a final cut. The device also comprises a handheld gauge holder that holds the gauge, slide scale, or ruler into place onto the table saw, securing the gauge into the opening of the table insert/throat plate of the table saw. The gauge may be moved relative to the handheld gauge holder to calculate saw blade depth.

The invention relates to a panel saw (1) for cutting plate-shaped workpieces (2) into multiple sections, comprising: a machine base frame (3); a workpiece support (4) with a sawing slot (5); a saw aggregate (7), which is arranged below the workpiece support (4), wherein a circular saw blade (6) is arranged on the saw aggregate (7), which circular saw blade (6) in a sawing position (34) protrudes through the sawing slot (5) and is displaceable in a sawing direction (8); a holding-down device (9) for clamping the workpiece (2) on the workpiece support (4); a positioning device (12) for positioning the workpiece (2).

A handheld power tool (100) comprising at least one orientation sensor (150) is provided. The handheld power tool (100) is operatively connected to a controller (160; 210) and said controller (160; 210) is configured to receive orientation data from the at least one orientation sensor (150), wherein the orientation data comprises information associated with an orientation of at least a portion of the handheld power tool (100) and to determine operational data based on the orientation data, said operational data representing work performed using the handheld power tool (100). The operational data is determined by determining the orientation of the power tool based on the received orientation data from the at least one orientation sensor (150).

An oscillating blade for cutting or shaping sheet materials such as drywall, with a blade, a sharing portion, a depth gauge for determining depth of cut, a caliper portion for premarking sheet materials for a standard dimension cut, and a reverse direction blade.

A mobile machine tool including a guide element, having a guide surface, for guiding the machine tool and a workpiece surface of the workpiece to one another along a machining path. The machine tool includes a drive unit having a drive motor for driving a tool receptacle arranged on the drive unit for receiving a work tool and a detection device for detecting at least one workpiece reference which is associated, with respect to a machining path, with a machining start point where the work tool starts the machining of the workpiece or with a machining end point where the work tool ends the machining of the workpiece. The tool receptacle is designed for rotationally driving the work tool about an axis of rotation and for adjusting a penetration depth of the work tool into the workpiece by means of a depth adjustment device between depth adjustment positions.

A tree processing system may include a tree processing head and a controller. The tree processing head may include a header frame, a motor, a saw, an arm, and a sensor. The saw is used to cut a tree when the saw is driven by the motor. The saw engages with the tree from a first position and to a second position. The first position and the second position define a cutting zone therebetween. The sensor is used to detect a saw operation speed or current. The controller is coupled to the sensor and configured to determine whether the second position is reached based upon an increase of the saw operation speed or current detected by the sensor. When the second position is reached, the controller transmits a resting signal to the tree processing head to perform a resting operation.

An adjustable positioning structure for a feeding support plate of a circular sawing machine contains a magnetic element, a micro pneumatic cylinder, and a control button. The magnetic element is accommodated in a magnetic slider which is fitted with a guide column on a material feeding side of a table of the circular sawing machine and is configured to produce a change of a magnet value of the magnetic slider when the magnetic slider moves along the guide column reciprocately, such that a displacement value of the magnetic slider is calculated and is displayed by a display on the magnetic slider. The micro pneumatic cylinder is mounted on the magnetic slider and is configured to fix or release the magnetic slider relative to the guide column. The control button is arranged on the feeding support plate and is configured to control the micro pneumatic cylinder to operate.

Post notch forming tool mounted on a handheld saw blade for forming a notch in a post end. The tool has a base, a handle, and two L-shaped members with bolt assemblies for attaching the tool to the saw blade. The base has a first extended lip which slides downwardly along the post's outer surface to guide the tool to form a 3-inch notch. A spacer member is selectively attached to the L-shaped members and has a second extended lip which slides downwardly along the post's outer surface to guide the tool to form a 1½ inch notch. Method steps include using the power saw blade to form a transverse cut intersecting the longitudinal axis, using the extended lip of the base to form a 3-inch notch, or attaching the spacer member and using its extended lip to form a 1½ inch notch in the post's outer surface.

An example pipe cutting tool includes a plurality of actuators and a plurality of cutters. Each of the plurality of cutters is connected to at least one separate actuator of the plurality of actuators. The at least one separate actuator is configured to move the cutter between a pre-deployed and deployed position. The deployed position is beyond the pre-deployed position. The plurality of cutters may include a first and second cutter, with the at least one separate actuator connected to the second cutter moving based, at least in part, on one or more cutting conditions. An example method of cutting a pipe includes extending a first cutter to contact the pipe, cutting at least a portion of the pipe using the first cutter, detecting a cutting condition, extending a second cutter based, at least in part, on the cutting condition, and resuming the cutting using the second cutter.
