Makita has launched a completely new range of high power SDS+ rotary hammer drills which "set new standards" in impact performance for 2kg and 3kg machines.

With high rpm levels, increased joules of impact energy and increased blows per minute, Makita claim these rotary hammer drills will dramatically improve site productivity with increased operator safety.

The new Makita HR2230 SDS+ 2-mode 710watt 2kg hammer drill delivers 2.3 joules of impact and up to 4,050 blows per minute. Weighing just 2.5kg and having a tri-axial vibration rating of just 15m/s2 in hammer mode, the HR2230 is ideally equipped for fixings and main installations on site. With similar features but with power increased to 780watts and 4,500bpm, the new Makita HR2460 has 2.7 joules of impact energy which will punch a 24mm hole into concrete.


With similar power and impact energy the 3-mode models in this new Makita hammer drill range, the HR2470, HR2470T and the HR2470X, offer the rotary only, rotary hammer and hammer-only mode options. The HR2470T model has a quick change chuck facility allowing replacement of the SDS+ chuck by a keyless chuck whilst the HR2470X is fitted as standard with a keyless chuck and adapter.

Safety is paramount with these powerful hammers which have an ultra low vibration rating of just 12.5m/s2 in hammer mode and 15.5m/s2 in rotary mode.

The 3kg hammer in the range, the Makita HR2811, has 2.9 joules of impact power: enough to drill 28mm in concrete and drive a 80mm TCT core though masonry. Weighing 3.3kg this powerful 800watt drill has an even lower vibration rating in hammer mode of just 11.5m/s2 and 15m/s2 in rotary use.

The new range of hammer drills are all equipped with torque limiters which disengage the motor drive should the drill snag when the operator is correctly holding the torque sensitive side-grip handle. This is easily adjusted for position around the gearbox casing. All main grip handles have the vibration reduction rubberised grip and the mighty HR2811 has the Makita designed and well proven 2-mass isolated handle assembly where the main grip handle is mounted on vibration absorbing springs and fulcrums.

This entire SDS+ Makita range of rotary hammer drills is available in either 110v or 240v configuration and is delivered with side handles and depth stop in a robust carry case.
