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.

A handle and a tool housing that includes features that matingly engage or receive portions of the handle. The handle is adapted to couple onto an exterior surface of the tool housing, and minimize damage caused to the tool when the tool is dropped with the handle attached. In an example, the handle includes a shaft and first and second clamping portions, where each of the first and second clamping portions includes a protrusion that engages a pocket or groove on the tool housing. The shaft extends through the first clamping portion and threads into the second clamping portion, and as the shaft is threaded into the second clamping portion the first and second clamping portions are moved closer together and clamp onto the tool housing.

The handle for a handheld power tool includes a grip portion which can be gripped by a user, a fastening portion by which the handle can be fastened to the handheld power tool, and an oscillation decoupling device which is designed to decouple oscillations acting on the fastening portion from the grip portion, wherein the oscillation decoupling device has a spring element with a settable spring stiffness.

Rotatable handles and related methods are disclosed herein. In one form, the handle has a first clamp member, a second clamp member connected to the first clamp member on one end and mating with the first clamp member at another end, and an actuator operable to drive the mated ends of the first clamp member and second clamp member together to create a clamping force between the first clamp member and the second clamp member and secure the rotatable handle into a fixed position with respect to an object to which the rotatable handle is connected. Various methods are also disclosed herein with respect to the rotatable handle.

A system includes: an add-on handle; and a hand-held power tool which includes a clutch setting ring, a chuck with clamping jaws and a handle fastening arrangement which is situated axially between a section of the chuck and the clutch setting ring. In at least one operating state the add-on handle fastened to the handle fastening arrangement and the clamping jaws of the chuck are situated in at least one plane which is oriented perpendicularly to a rotation axis of the chuck.

An installation tool for fastening a top plate to a roof support member and other structural connections is adapted to drive threaded fasteners at a pre-established angle. The tool preferably includes a rotary driver assembly and a telescopic tube assembly. A guide head assembly is mounted adjacent the outer end of the telescopic tube assembly. Locating or reference structures function to properly precisely set the drive angle of the fastener. Various indicators mounted to the guide head indicate the flush position of a locating surface or reference structure. The flush indicators may employ a projection, a flag, an LED or an audio module.

An accessory for a fastening gun includes a magazine assembly with a feed end and a discharge end and configured to support a series of staples in a pre-discharge orientation and with a feed mechanism for feeding the staples from the feed end to the discharge end. A drive member guide assembly is mounted on the magazine assembly and is configured so that a staple drive member can be mounted in the drive member guide assembly and can be driven and retracted along a predetermined path with respect to the magazine assembly, so that, when driven, the drive member can engage a staple to drive legs of the staple into respective components, the drive member guide assembly being configured for mounting on the fastening gun with the drive member connected to a piston or the like of the fastening gun.

A handle (200) for use with a power tool (100) having a coupling portion (204) and a gripping portion (206). a connector (228) for connecting the gripping portion (206) to the coupling portion (204), and a resilient deformable member (256) provided with and extended along the gripping portion (206). The coupling portion (204) is configured to detachably couple the handle (200) to the power tool (100). The gripping portion (206) is in connection with the coupling portion (204) for gripping by a user. The resilient deformable member (256) and the gripping portion (206) are integrated along length for simultaneous deformation.

A power tool includes an accessory and a reader. The accessory is configured to be attachable to and detachable from the power tool. The accessory includes a passive wireless tag. The reader includes at least one antenna and a reading part. The reading part is electrically connected to the at least one antenna. The reading part is configured to wirelessly communicate with the wireless tag via the at least one antenna and to read information stored in the wireless tag when the accessory is attached to the power tool.
