1. PRODUCT NAME Hitachi 130 mm (5") Reciprocating Saw, Model CR 13VA 2. MARKETING OBJECTIVE 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. The Model CR 13VA is at

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. Such inconvenience was a cause of inefficient operation because the operator kept using a dull

5-2. Optional Accessories The cutting speed of the Model CR 13VA is substantially higher than that of the current model, however, the conventional HCS blades may be broken in heavy applications such as house demolition, etc. To cope with this problem, the BI-METAL blades shown in Table 2 are provided. The BI-METAL blades are tough and rarely break since they are made by electron-beam welding together of two different types of steels. A very hard steel called "DM05" (JIS: SKH51 or equivalent m
