The multi-angle bit holder on this SDS max hammer allows the chisel to be rotated to multiple positions to suit the application The HiKOKI DH40MCJ2Z is a 110V Rotary Demolition Hammer with an SDS Max Shank. HiKOKi is the new brand name for Hitachi. The Shank has one push bit mounting, it only takes one action instead of conventionally required two to mount a drill bit. All that needs to be done is insert the drill bit into the tool holder while turning it. The high-performance machine has a faster drilling speed and better demolition performance than previous models. Boasting superior working comfort with a larger damper and higher volume air cushion reduces the impact and piston reaction force generated during hammering. This results in significant vibration reduction. Fitted with a large change lever located on top of the tool for easy visibility allowing smooth mode changing. Hammering (for demolition), Neutral (for bit angle adjustment) and Rotation + Hammering (for drilling). Multiple bit-angle settings enable the chisel to be rotated at 12 different angles with the change lever positioned at \'neutral\'. A large trigger switch is easy to grip and fits the hand for more control with less fatigue. Comes in 110V and 240V (DH40MCJ1Z) models. Sold without drill bit.
