【Amazon.co.jp限定】HiKOKI(ハイコーキ) 36V 充電式 ロータリハンマドリル DH3628DA SDSプラスシャンク 蓄電池1個・充電器・ケース付 DH3628DA(XPZ)

Drilling into concrete is often plagued by two main frustrations: the difficulty of maintaining a perfect vertical angle and the cumbersome nature of power cords. The HiKOKI DH3628DA solves these pain points by combining the raw power of the MultiVolt 36V system with the freedom of cordless operation and an industry-first "LED Vertical Support Function." This feature provides visual feedback via LED lights to indicate the tool's tilt before drilling, significantly reducing the risk of crooked holes—a critical advantage for those who lack extensive experience or are working in awkward positions. Beyond precision, the tool focuses on operational safety and efficiency. The Auto-Stop function remembers the drilling time and cuts the motor automatically, which prevents the tool from suddenly plunging or kicking back upon breakthrough. Furthermore, the design allows for the attachment and detachment of the dust collection system (sold separately) without needing to remove the drill bit, streamlining the workflow in dusty environments. As an Amazon-exclusive bundle, it includes a first-time repair warranty, providing a safety net for professional users who push their equipment to the limit. Its lightweight and compact chassis makes it far more manageable for overhead work or confined spaces compared to traditional heavy-duty rotary hammers.
