The Makita HM1214C AVT Demolition Hammer is a 10kg class demolition hammer adapted for SDS Max bit...The Makita HM1214C AVT Demolition Hammer is a 10kg class demolition hammer adapted for SDS Max bits. It features AVT (Active dynamic Vibration absorber Technology) for reduced vibration during chipping and suppression of motor speed when no load, further reducing vibration when idling. Its in-line tool design is perfect for downward vertical applications. This hammer produces constant speed, even under load, and its soft start restricts the initial inrush to provide a controllable ramp-up of speed. It is fitted with a one-touch sliding chuck for easy bit installation and removal, and an LED lamp indicates when it's time to replace the carbon brushes. Supplied with: 1 x SDS Max Bull Point Chisel, 1 x Tube of Bit Grease, 1 x Side Handle and 1 x Carry Case. Specifications: Mode: Chisel Only. Input Power: 1,500W. Impact Rate: 950-1,900/bpm. Impact Energy: 19.9 joules. Chuck: SDS Max. Bit Angle Setting: 12 Stage. Weight 11.7kg.
This guide is for professionals and serious DIYers looking to understand and effectively use the Makita HM1214C AVT Demolition Hammer. The primary benefit is its powerful demolition capabilities combined with reduced vibration, thanks to the AVT technology, leading to greater comfort and control during use. However, its weight of 11.7kg means it is best suited for heavier-duty tasks.
