摘要： A method to control a power tool (1), especially a handheld core drilling machine, includes a drive (10) to drive a tool (30) and a control unit (40) for when a workpiece (W) is being processed. The method encompasses the following method steps:setting the rotational speed of the drive at a first value;measuring a first power consumption value for the drive;setting a threshold value for the power consumption of the drive; andincreasing the rotational speed of the drive to a second value if the power consumption of the drive (10) exceeds the threshold value due to an increase in the drive load.The power tool includes a drive (10) to drive a tool (3) and a control unit (40) to control at least the rotational speed of the drive.

摘要： A ring saw includes a ring saw blade, a tool holder that guides the ring saw blade in a cutting plane, a motor, and a driving wheel where the ring saw blade is drivable in the cutting plane by the driving wheel and the driving wheel is coupled to the motor. A guide roller is disposed on a first side of the cutting plane where the ring saw blade is guidable by the guide roller from the first side. A guide roll is disposed on a second side of the cutting plane where the ring saw blade is guidable by the guide roll from the second side. The guide roll is disposed in a hood that is pivotable relative to the cutting plane.

摘要： A handheld core drilling device includes a tool receptacle where the tool receptacle has a receiving sleeve and a tool receiving piece disposed in the receiving sleeve. A compression spring arrangement is disposed within the receiving sleeve. Exactly three equally spaced retaining tabs are formed on the receiving sleeve along a circumferential direction and each retaining tab has a respective stop surface that faces the tool receiving piece. Exactly three equally spaced bearing surfaces are formed on the tool receiving piece along a circumference of the tool receiving piece and each bearing surface faces a respective stop surface. Each of the bearing surfaces includes a stud with a stud surface where the stud surfaces in a radial direction are at most half as wide as the bearing surfaces in the radial direction.

摘要： A method is provided for controlling a power tool (1) when a material (W) is being worked, including the steps: the rotational speed of a drive (20) of the power tool is set to a first value; a first temperature value is measured; the first temperature value is compared to a pre-specified threshold value; the rotational speed of the drive (20) is reduced from the first value to a second value if the first temperature value exceeds the pre-specified threshold value for a pre-specified first period of time; a second temperature value is measured; the second temperature value is compared to the pre-specified threshold value; and the rotational speed of the drive (20) is raised from the second value to the first value if the second temperature value has fallen below the pre-specified threshold value for a pre-specified second period of time.

摘要： A ring saw blade includes a flat annular support which has a side face and an outer circumference. One or more cutting elements are disposed along the outer circumference. An annular groove is recessed into the side face and has a radially inner flank and a radially outer flank. The radially inner flank is conical and a first cone describing the radially inner flank has a half opening angle of between 10 degrees and 30 degrees.
