Review

This Amazon.co.jp exclusive bundle combines the HiKOKI 3.6V Cordless Impact Driver WH3DA(JS) with a 5-piece set of No.2 Plus Bits (0031-9390) [S1]. Key features include an industry-first joystick switch and a 3-stage slow mode (600 / 1,000 / 1,300min-1) designed to reduce damage from over-tightening and prevent cam-out during temporary fastening [S2]. The unit utilizes a high-capacity tabless battery (BCL350T), capable of driving approximately 200 wood screws (Φ3.8×32mm) or 2,400 machine screws per charge [S1, S2]. For versatility, the tool can be switched between pistol and straight shapes to fit various workspaces [S2]. A one-year initial repair warranty is included for the main unit, provided it is sold and shipped by Amazon.co.jp; however, the battery and charger are excluded from this warranty [S1]. The included No.2 bits are 100mm long and suitable for wood screws (3.1-4.8mm) and small/tapping screws (3-5mm) [S1].
