A drilling operation is assisted to form an intended hole in a drill target. An attachment is attachable to an earth auger. The earth auger includes a motor housing accommodating a motor, a handle housing located behind the motor housing and including a grip portion receiving a trigger switch operable to activate the motor, a gear housing located in front of the motor housing and accommodating a gear, and a rotation output unit protruding downward from the gear housing to receive a drill bit. The attachment includes an auxiliary pole to be located adjacent to the drill bit and extendable in a vertical direction.

An impact tool includes a housing extending along a longitudinal axis. The housing includes a motor housing portion, a first handle extending from the motor housing portion, and a front housing coupled to the motor housing portion opposite the first handle. The impact tool also includes a motor supported within the motor housing portion, an anvil extending from the front housing, an impact mechanism supported within the front housing, and an auxiliary handle assembly. The auxiliary handle assembly includes a mount coupled to the housing, an auxiliary handle coupled to the mount and spaced from the first handle, and an adjustment mechanism. Loosening the adjustment mechanism permits rotation of the auxiliary handle assembly about the longitudinal axis relative to the housing, and tightening the adjustment mechanism secures the auxiliary handle assembly in a selected rotational position.

A removable attachment assembly for a ninety degree drill assembly, which includes a base member and a securement assembly secured to the base member for releasably securing the base member to a housing of the ninety degree drill assembly. The removable attachment assembly further includes a cushion member releasably securable to the base member.

A power tool includes a handle detector that is less susceptible to vibrations and is highly durable and reliable. A grinder includes a brushless motor, an inner housing accommodating the brushless motor, a rubber cylinder, a spindle driven by the brushless motor, and an outer housing enclosing the inner housing and holding the inner housing with the rubber cylinder in between. The outer housing includes a handle mount and at least one handle detector that detects a side handle attached.

A handle device for releasable fastening on a hand-held power tool (10), wherein the handle device has a clamping ring (41) with a clamping mount (42) for receiving a fastening portion (20) of the hand-held power tool (10) and also has a handle (60), which projects from the clamping ring (41), wherein a clamping-actuation grip (78), which can be activated manually by the operator (BE), can be used to adjust the clamping mount (42) between a clamping position (K), and a release position (L), and wherein the handle device has an axial-form-fitting body (80), which is mounted in a movable manner in relation to the clamping mount (42) and has an axial-form-fitting contour (81) for engagement in a mating axial-form-fitting contour (25) of the fastening portion of the hand-held power tool. Provision is made for the handle device to have a form-fitting-actuation grip (90), which is separate from the clamping-actuation grip (78), can be activated manually by the operator (BE), independently of the clamping-actuation grip, and is intended for adjusting the axial-form-fitting body (80) between an engagement position, and a freeing position.

A tool includes a first accessory, at least two first attachment portions for detachably and selectively attaching the first accessory, and a single first intermediate member provided in common for the at least two first attachment portions. The first intermediate member includes at least one pressed portion configured to, when the first accessory is attached to one first attachment portion arbitrarily selected from the at least two first attachment portions, be directly or indirectly pressed by the first accessory. The first intermediate member is configured to be displaced when the at least one pressed portion is pressed. The tool further includes a single first sensor configured to detect that the first intermediate member is displaced.

An impact tool (1) includes: a motor (10); an impact mechanism (15), which is rotatable about an output rotational axis (BX) and is driven by the motor; an anvil (16) having an anvil shaft (113) disposed forward of the impact mechanism; and at least one anvil projection (114) protruding radially outward from a rear-end portion of the anvil shaft and configured to be impacted by the impact mechanism in a rotational direction; a hammer case (6) housing the impact mechanism; a main-body housing (2) disposed rearward of, and fixed to, the hammer case; a grip housing (3) having at least a portion disposed rearward of the main-body housing, the grip housing being coupled to the main-body housing so as to be movable relative to the main-body housing; and at least one vibration-isolating member (138, 139) disposed between the main-body housing and the grip housing.

A side handle can be toollessly positioned on a tool body, and is attachable to power tools of multiple models and is highly versatile. A side handle is attachable to a side surface of a tool body included in a power tool. The side handle includes a rotation locking member attachable to the tool body in a manner of being restricted from rotating, and an operable portion operable to lock and unlock a position of the side handle relative to the rotation locking member.

A power tool includes a side handle that can be toollessly positioned and also attached to or detached from a tool body. The power tool includes a tool body having a side surface, a side handle on the side surface of the tool body, and an operable portion operable to attach or detach the side handle to or from the tool body and to position the side handle being attached to the tool body.

A tool includes a prime mover, switch, operation member for the switch, first accessory, second accessory, third intermediate member moved in conjunction with displacement of the operation member, first intermediate member configured to be displaced from a first blocking position of blocking a displacement route of the third intermediate member to a first non-blocking position of not blocking the displacement route by attachment of the first accessory, and second intermediate member configured to be displaced from a second blocking position of blocking the displacement route to a second non-blocking position of not blocking the displacement route by attachment of the second accessory. Only when the first intermediate member is located at the first non-blocking position and the second intermediate member is located at the second non-blocking position, the third intermediate member is permitted to be displaced so that the operation member is permitted to be displaced to the ON position.
