摘要： A grinder includes a brake mechanism configured to brake a spindle and an electrical actuator (a solenoid) that actuates the brake mechanism. The solenoid actuates the brake mechanism in conjunction with a turning OFF of a switch from a driving state of a motor, and releases an actuation of the brake mechanism after a lapse of a predetermined period of time from the turning OFF of the switch.

摘要： A dressing blade for finishing and reconditioning new and used abrasive grinding and cutting tools has a slab-shaped shank with an extension protruding longitudinally from the shank. Superabrasive grains are disposed on the surface of the extension and held in place by a brazed metal composition. This composition is formed by brazing a powdered mixture of brazing metal components and active metal components. Specific extension configurations are provided which allow aligning the superabrasive grains in single layer arrangement for precise dressing and simple fabrication of the tool. The novel dressing tool exhibits excellent wear characteristics.

摘要： An output shaft of a motor is divided into a front shaft (first or second front shaft) and a rear shaft. The first front shaft is to be rotatably supported by a first shaft support plate connected directly to a motor housing. The second front shaft is to be rotatably supported by a second shaft support plate connected to the motor housing with a spacer provided between the second shaft support plate and the motor housing. A braking mechanism including a flange plate, a braking member and a biasing member is mounted to the second shaft support plate and the second front shaft. The first front shaft is used with the first shaft support plate to realize a power tool without the braking mechanism. The second front shaft is used with the second shaft support plate and the spacer to realize a power tool without the braking mechanism.

摘要： A back-up pa supporting and releasably engaging an abrasive article. The back-up pad comprises: a body including a front surface and a back surface in which the front surface comprises a first attachment component thereon and the back surface comprises a second attachment component thereon, and each of the attachment components is adapted for releasable engagement with an abrasive article; a reinforcing plate located within the body between the front surface and the back surface; and tool securing means on the body for securing the back-up pad to a power tool and for selectively orienting the back-up pad in one of a first orientation and a second orientation. When the back-up pad is in the first orientation, substantially the entire front surface is exposed for contacting a workpiece, and when the back-up pad is in the second orientation, substantially the entire back surface is exposed for contacting a workpiece.

摘要： A pneumatic power tool includes: a housing with a pressure air inlet passage, a rotation motor, a working implement carrying output shaft, and an over-speed safety device including: a valve element located in the inlet passage and shiftable between open and closed positions, a motor speed responsive actuating mechanism which can shift the valve element from an open to a closed position as motor speed reaches an accepted maximum limit, and a retaining unit which maintains the valve element in an open position at normal motor speed levels and releases it toward the closed position when actuated by the actuating mechanism. The retaining unit includes: a latch spindle having varying width in an axial direction and coupled to the actuating mechanism for displacement between valve element locking and releasing positions at the maximum speed limit, and a support surface and axially adjacently located one or more waist portions.
