Abstract
A hand-held electrically powered cut-off tool (100, 200, 800,1000,1900, 2500) comprising a first part (110) and a second part (120) arranged vibrationally isolated from each other, the first part (110) comprising an interface (2510) for holding a cutting tool (130) and an electric motor (140) arranged to drive the cutting tool, wherein the first part is associated with a first mass (M1), the second part (120) comprising a battery compartment (150) for holding an electrical storage device (220) arranged to power the electric motor (140) as well as front (190) and rear (195) handles for operating the cut-off tool, wherein the second part is associated with a second mass (M2), wherein the electrical storage device (220) is associated with a third mass (M3), and wherein the cutting tool is associated with a fourth mass (M4), wherein a ratio of the second mass (M2) to the sum of the first and second masses (M1+M2) is at least 0,3, and preferably more than 0,35; wherein a ratio of a sum of the second and the third mass (M2+M3) to the sum of the first and fourth masses (M1+M4) is at least 0,6, and preferably more than 0,8 and even more preferably more than 1,0; wherein a ratio of a sum of the second and the third mass (M2+M3) to the sum of the weight of the entire device including electrical energy storage and cutting disc, is at least 0,45, and preferably more than 0,5.
Description
technical field [0001] The present disclosure relates to electric hand-held work equipment such as chopping tools and saws for cutting concrete and stone. Background technique [0002] Hand held work tools for cutting and / or grinding hard materials, such as concrete and stone, include high powered electric motors to provide the power needed to process the hard materials. These motors generate a lot of heat and therefore need to be cooled to prevent overheating. Electric work tools generate heat from the electric motor as well as from the battery and control electronics. An efficient method for cooling such work tools is needed. [0003] Work tools also typically generate vibrations that can be harmful or at least cause discomfort to the operator of the tool. It is desirable to protect the operator from prolonged exposure to strong vibrations. [0004] The environments in which these types of tools are used are often harsh. Work tools are exposed to water, dust, debris, ...
