Makita HM1214C/1 10Kg SDS-Max Demolition Hammer With AVT 110V

The Makita HM1214C is a 10kg-class demolition hammer adapted for SDS-MAX bits. The main features are as follows: AVT (Active dynamic vibration absorber) for reduced vibration during chipping. Suppression of motor speed during no-load for reduced vibration when idling. In-line tool design optimum for downward vertical applications. High work efficiency.

Features

• Anti-Vibration Technology is an internal counterbalance system that greatly reduces vibration and directs more impact energy to the work surface for increased user comfort and greater productivity


• Constant speed control automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs


• Soft start suppresses start-up reaction for more precision and better accuracy


• Variable speed control dial enables user to match the speed to the application for greater versatility


• L.E.D. service light notifies the user approximately 8 hours before the brushes need to be replaced


• L.E.D. power light indicates switch failure or cord damage


• Extended life brushes are longer for more work between service intervals and less downtime


• Automatic brush cut-off protects commutator from damage for longer tool life


• 12 bit angle settings allow the bit to be set at different positions for operating convenience


• One-touch chuck allows for quick bit changes


• "No hammering when idling" function helps increase tool life


• Easy-to-operate slide switch increases productivity and allows for continuous use


• Side handle swivels 360° for greater control


• Rubberized ergonomic soft grip provides more comfort

AVT TECHNOLOGY AVT is the new amazing anti-vibration technology from Makita and the way forward in protecting against the effects of vibration related injury, it is a milestone in user safety andreliability, setting a benchmark for others in the power tool industry to follow. AVT was born from research carried out in California at the Seismic Research Unit; originally these systems were set up to measure the strengthof earthquakes bymonitoring the tremors they created. This in turn started the process that gives birth to AVT, scientists tried to counteract these tremors by fighting the waves using Dynamic Damping, this Dynamic Damping is the principal onwhich AVTis based. Dynamic Damping is essentially a way of moving energy so it drains away from the object you are holding; the more heavily damped the system the faster the energy drains away. There are various ways of achieving this i.e. using a mechanical damper which is effectively a counter balance weight which, provides an equal and opposite anti-vibration force that puts an equal mass directly opposite the point at which the striker bolt delivers the impactjoules to the drill bit, saw blade or breaker steel, this eliminates vibration as the power increases, without the dissipation of power through vibration more of the generated energy in the motor can be delivered to thetool bititself. There is also a Dynamic Vibration Absorber, which shifts the air pressure in the crank, and the barrel room actively controls the balancer to move it to the opposite sides of the piston.
