摘要： A powered hammer includes a housing having a proximal end and a distal end. The distal end includes an opening for a tool to pass through. The powered hammer further includes a shroud member coupled to the housing and configured to surround an outer surface of the distal end of the housing. The shroud member includes an opening on a lower surface thereof. The opening is configured to allow the tool to pass through. The shroud member is made from a ceramic material with a layer of fiber glass disposed adjacent to the outer surface of the distal end of the housing. The shroud member is configured to reduce heat transfer to the housing from an ambient environment proximate the distal end of the housing.

摘要： Device and method for milling of materials including a milling cutter body including a first end portion and an opposite second end portion. The first end portion is connected to a rotatable spindle and the second end portion is provided with at least one cutting edge. The milling cutter body defines a longitudinal axis and is provided with an axial recess, wherein at least one mass element is arranged in the recess. The axial position of the mass element in relation to the milling cutter body is tuned by use of tuning members included in the device for the tuning of the natural frequency of the device. The mass element is axially locked in relation to the milling cutter body by use of lock members included in the device, in order to optimize the natural frequency of the device for the milling operation in question.

摘要： A chisel bit of a percussion tool for penetrating hard surfaces includes a shaft having a mounting end, a working end and upper and lower protuberances formed along its length. The upper protuberance provides for retaining the mounting end of the shaft within a body of the percussion tool. The lower protuberance forms a retaining collar beyond the body of the percussion tool against which a resilient extractor is mounted along the shaft. The resilient extractor includes an elastomeric member that is positioned by the retainer collar along the shaft to contact the hard surfaces penetrated by the chisel bit and exert a resilient bounce back force against the hard surfaces when the chisel bit has penetrated to a given depth to prevent the chisel bit from becoming stuck in place.
