    摘要： A machine tool (1) is provided, in particular an angle grinder, including a spindle (8) that can be driven about a rotational axis (L), a device (9) being provided which can be fixed to the spindle (8) by a rotary connection. A separate securing device (26) is provided which is operatively connected to the spindle (8), which is arranged on the output side of the device (9), at least in some regions, and which, at least during operation of the machine tool (1), has a smaller outer diameter (28), at least in some regions, with respect to the rotational axis (L) than an outer diameter (14) of the spindle (8).

    摘要： A handheld, hand-guided cutting-off machine (10), which includes a rotating cutting-off wheel, a supporting housing part (36), an output shaft, which is rotatably supported around an output axis (40), a drive motor, a transmission mechanism (19), which connects the drive motor to the output shaft, a flange and a safety guard (24), which covers the cutting-off wheel over a covering area. The cutting-off wheel is rotatably fixedly mounted on the output shaft with the aid of the flange and surrounded by the safety guard (24), which is pivotable around a pivot axis. The safety guard (24), the supporting housing part (36) and the transmission mechanism (19) have maximum distances from the output axis (40) over an outcut angle (θ), which are less than or equal to half the flange diameter of the flange.

    摘要： A guard attachment for a grinding tool has a metal body with an upper surface, a side wall along part of a perimeter of the upper surface, and a connector with which it can be attached to a grinding tool. Additional features include a bottom plate opposite the upper surface and a debris outlet attached at one end to the surface and side wall of the guard, and having a magnet removably attached to the other end. The bottom plate swivels outward from the body of the guard to facilitate changing the wheel or disk of the grinding tool. The magnet has an aperture allowing for the passage of air, but prevents sparks from escaping the guard attachment.

    摘要： A grinder (100) includes a motor (12), a housing (4, 6, 30), a spindle (24), a first cover (120), and a second cover (170). The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The first cover is provided in the circumferential direction of the spindle, is fixed to the housing, and at least partially covers a tool accessory (40), which is mounted on the spindle, from above. The second cover is detachably mounted on the housing (6) independently of the first cover.

    摘要： A stop lever is provided for a power tool having a gear case and a guard member. The reversible stop lever is coupled to the gear case via a fastener. The stop lever includes a first arm and a second arm, and the fastener is removable to position the stop lever such that the first arm or the second arm of the stop lever engages the guard collar. The first arm includes a first surface and a second surface that are angled such that the guard collar can be rotated in a one direction without actuation of the second arm, but not in the opposite direction. The second arm of the stop lever includes surfaces that are angled to prevent rotation of the guard collar in either direction unless the second arm is actuated about the fastener.
