  • Page 3: Product Name

    There is increasing demand for a high-speed and powerful saber saw in overseas markets. The new Model CR 13VA, which features a powerful motor and a swing cutting action, has been developed to meet that market demand. The swing cutting action is a new technology, in which the saw blade is swung like a pendulum, regardless of whether the saw blade is mounted upward or downward.

  • Page 4: Selling Point Descriptions

    4-1. Selling Point Descriptions (1) Fast cutting speed The Model CR 13VA can cut various construction materials fast and efficiently thanks to the high-power motor whose maximum output is over 1000 W (Model CR 10V: 680 V). (2) Saw blade can be mounted and removed without the use of tools (patent pending) Generally, conventional saber saws required a blade holder and a bolt to secure the saw blade.
  • Page 5 (3) Saw blade can be mounted in either direction, upward or downward The Model CR 13VA is convenient for cutting materials on the floor or near window frames, and also for plunge cutting on plywood panels because the saw blade can be installed upside down.
  • Page 6 (5) Dust- and water-resistant triple-sealing construction <patent pending> The Model CR 13VA has a triple-sealing construction to protect from the large amount of dust generated when cutting construction materials, autoclaved lightweight concrete, etc. and also from waste water when cutting pipes.
