    Thanks to the weight reduction of the motor, decelerating and cutting mechanisms, the Model CL 10D2 weighs only 3.2 kg even though it uses the 12 V battery while the Model CL 10D using the 9.6 V battery weighs 3.4 kg.

  • Page 5: Selling Points

    A safer and better working environment without fear of fire or scattering of chips and dust is ensured because the Model CL 10D2 does not produce the chips, dust, and sparks unlike cut-off machines and disc grinders. Shearing force: 2500 kg...
  • Page 6 The Model CL 10D2 is compact, lightweight, and cordless, so it is easily transportable and particularly convenient for cutting off hanged studs. In addition, it is capable of cutting up to 550 studs per single charge, so it has sufficient operability to cut many studs at floor level as well.
  • Page 7 In conventional cutting with a cut-off machine or disc grinder, considerable time is required for deburring after the studs have been cut. In actual tests, the Model CL 10D2 is approximately three times more efficient than cut-off machines or disc grinders.
  • Page 8 L-shaped angles, in order to prevent damage of the lagging. As illustrated, the Model CL 10D2 permits cutting of studs within an L-shaped angle measuring 25 mm x 25 mm x 3 mm (t).
  • Page 9 (8) Convenient stud mounting hole facilitates cutting studs to specified lengths The stud mounting hole is very convenient when cutting many studs to the same length at floor level. The adjustable stud mounting hole permits mounting of M6 to M10 studs, and can be used as an accurate cutting length guide for the full range of applicable studs.
