A drill for installing mine roof bolts is also disclosed. A method for installing mine roof bolts is also disclosed.

A drilling end effector is provided for drilling a workpiece having a workpiece surface. The drilling end effector includes a chuck configured to hold a drilling tool, and a nosepiece configured to at least partially surround the drilling tool when the drilling tool is held by the chuck. The nosepiece includes an end portion. The nosepiece includes at least one suction cup and at least one suction feed line. The at least one suction cup is fluidly connected to the at least one suction feed line. The at least one suction feed line is configured to be fluidly connected to a suction system. The at least one suction cup is configured to be engaged in physical contact with the workpiece surface and pulled under suction by the suction system such that the at least one suction cup adheres to the workpiece surface to thereby hold the end portion of the nosepiece on the workpiece surface.

A method for treating an interior weld joint located along an inner surface of a pipe includes the steps of: (a) advancing an internal grinder device within the pipe to the interior weld joint, wherein the internal grinder device includes a hollow housing that has a first open end and a first grinding implement that is disposed within the hollow housing and coupled thereto with a first biasing member; and (b) controllably rotating the hollow housing to at least a threshold speed at which time and under centrifugal force, the first grinding implement moves from an at rest retracted position to a deployed position in which the first grinding implement extends radially beyond the first open end for contacting and grinding the interior weld joint as the hollow housing and the first grinding implement are rotated.

The invention relates to a suction device for suctioning off wood chips and/or dust generated during the cutting machining of a workpiece, in particular for a chuck (10) for receiving a rotationally driven cutting tool (12), particularly a cutting tool for machining CFK materials or other short-chipping materials, comprising a hub portion (14) that can be rotationally driven, which supports a plurality of radial blades (16) that are evenly distributed in a circumferential direction. In each case, a blade entering edge (20) of the blade (16) extends axially away from the hub portion (14) and radially outwards to a ring portion (18) that stabilizes the blades (16) and is concentric with respect to the hub portion (14). The invention further relates to a production method for producing the suction device.

A shroud for a dust extractor comprises: a body portion including a tubular housing forming a passageway and having a first and second inlets defining first and second openings; an engaging portion including a tubular housing forming a passageway, the tubular housing connecting to a third opening formed through a wall of the body portion to connect the passageway of the engaging portion with the passageway of the body portion on one end, and including a third inlet defining a fourth opening on another end; and a seal mounted in the second inlet of the body portion, the outer edge of the seal being attached to the periphery of the second inlet, the seal projecting radially inwardly towards the longitudinal axis of the tubular body.

A dust-proof drilling apparatus and method are disclosed which includes a body having a motor, a drill bit, a handgrip, and a power switch; an air suction unit, directly connected to the front of the body, designed to create an axial flow of air from the drill bit toward the body; and a dust collecting unit, directly and removably connected to the front of the air suction unit, designed to collect dusts and materials from the drilling operation of the drill bit, wherein the body, the air suction unit, and the dust collecting unit are connected sequentially along the axis of the drill bit.

Wall sealing and penetrator apparatus for use in penetrating walls in dangerous conditions. An example wall sealing and penetrator apparatus includes a first portion comprising: a first housing, a first sealing element, a first vacuum port; and a second portion comprising, a second housing, a second sealing element, a second vacuum port, and a cutting element.

A suction device for a hole saw of a hand-held power tool oscillatingly driven about an oscillation axis. A substantially disk-shaped base body has a first side that faces the hand-held power tool and a second side that faces the hole saw. A fastening section detachably fastens the suction device to an oscillatingly driven hand-held power tool; and a connecting piece connects the suction device to a suction apparatus.

A dust collector includes body, a dust-storing part, a sliding part, a dust-transfer passage, and a biasing member. The sliding part is held by the body to be slidable in a specified axial direction and has a suction port. The dust-transfer passage connects the suction port and the dust-storing part. The biasing member biases the sliding part in a first direction of the axial direction. The sliding part is configured to be normally held in an initial position in which the sliding part protrudes from the body by a specified length in the first direction, and to be moved in a second direction opposite to the first direction against the biasing force when pressed in the second direction. The dust collector includes a cushioning member configured to be interposed between the body and the sliding part in the axial direction when the sliding part is placed in the initial position.

A machining support configured to reduce spring back of a sheet following a machining operation on the sheet is presented. The machining support comprises a porous material with a plurality of surfaces including a support surface having a contour configured to contact and support the sheet; sealing material covering each of the plurality of surfaces except the support surface; and a vacuum port configured to provide a vacuum to the porous material.
