The present invention refers to a device that is coupled to motorised tools whose consumable or implement rotates, preferably tools of the portable or swivelling type, supplying fluids either to the surface on which the consumable or implement acts, or to the consumable or implement itself so that it performs its function correctly, having a reservoir in which pressure is generated for its use and the device and the tool or consumable that is used being independent and interchangeable, and having conventional means of attachment that allow it to be used in conventional tools without having to adapt the tool, the consumable or implement.

A glass polishing device has a casing adapted for operative engagement with the exterior surface of a powered drill motor. The casing includes a handle extending from a second side opposite an opening in an opposite first side thereof from which a handle of the engaged drill motor projects. A triggerable fluid supply is coupled to the casing and projects fluid to a tool or a section of glass being resurfaced by the tool.

A water supply apparatus for the supply of water to a machine tool, including a water pump, a water accumulator device, a suction line, a supply line and a valve device reversibly adjustable into a first and a second position. The water pump is positioned downstream of the valve device. A first connecting line, a second connecting line and a return line are provided. Here, in the first position, the first connecting line, the second connecting line and the return line are connected to one another such that water can be conveyed from the water pump, from the first connecting line, from the second connecting line, from at least a part of the suction line and from at least a part of the supply line into the return line, and, in the second position, the first connecting line, the second connecting line and the return line are not connected to one another.

A fastener driving machine provided with a mechanism to lubricate pins or racks is realized. A fastener driving machine includes a driver blade, pins, and a lubricant feeding mechanism. The driver blade can reciprocate in a first direction and a second direction opposite to each other, and hits a fastener when the driver blade moves in the first direction. The pins respectively engage with racks provided on the driver blade to move the driver blade in the second direction. The lubricant feeding mechanism supplies lubricant to the racks and the pins.

A power tool comprising a body (110) arranged to support a rotatable work tool (120), the body comprising a front handle (130) and a rear handle (140), wherein the front handle is arranged between the rotatable work tool and the rear handle, the power tool comprising a liquid dispensing system (151,152, 153, 155) for adding a controlled amount of liquid to the rotatable work tool, the liquid dispensing system comprising a valve (153) for adjusting a flow of liquid in the liquid dispensing system, wherein the valve comprises a control member (154) arranged on the body adjacent to the front handle such that the control member is operable by a hand gripping the front handle.

A debris receptacle for a router table includes an enclosure configured to be attached to the router table. The enclosure defines an interior sized and shaped to receive a router. The enclosure defines a debris inlet aperture in fluid communication with a router bit aperture of the work platform so that the interior receives the debris from router bit aperture via the debris inlet aperture. The enclosure also defines a debris outlet aperture in fluid communication with a dust collector to remove debris from the interior. The enclosure further defines an air inlet aperture in fluid communication with air in an environment outside the enclosure. The debris receptacle also includes an air intake conduit for fluidly coupling the air inlet aperture to an air inlet of the router, thereby enabling the router to draw air into the router from the environment outside the enclosure to cool the router.

A driving tool includes a driver for driving a driving material and an elastic material for biasing the driver downward. The driving tool includes a lifter that is rotated by an electric motor. The lifter moves the driver to a top dead center against a biasing force of the elastic material. The driver includes a plurality of linearly arranged engaging teeth. The lifter includes a plurality of peripherally arranged engaging pins that are engageable with the plurality of engaging teeth. The lifter also includes a wheel that comprises a plurality of peripherally arranged pin supporting holes, each of which holds an end of the corresponding engaging pin. The lifter includes a grease groove and a recessed grease reservoir adjacent to the grease groove. The grease groove is formed in a pin supporting hole, such that the grease groove extends in a pin supporting hole extending direction.

A lubrication monitoring arrangement (1) is disclosed configured to monitor a supply of lubricant in a lubrication system (3) of a hand-held cutting tool (5). The arrangement (1) comprises a heating element (13) and a control unit (15). The heating element (13) is arranged to heat a portion (17′, 17″, 17′″, 17″″) of the lubrication system (3). The control unit (15) is configured to monitor the supply of lubricant in the lubrication system (3) by monitoring the change in temperature of the portion (17′, 17″, 17′″, 17″″) of the lubrication system (3). The present disclosure further relates to a hand-held cutting tool (5), and a method (100) of monitoring a supply of lubricant in a lubrication system (3) of a hand-held cutting tool (5).
