Product Overview
A rotary hammer, also called rotary hammer drill is a power tool that can perform heavy-duty tasks such as drilling and chiseling hard materials. It is similar to a hammer drill in that it also pounds the drill bit in and out while it is spinning.
However, rotary hammers use a piston mechanism instead of a special clutch. This causes them to deliver a much more powerful hammer blow, making it possible to drill bigger holes much faster. Most rotary hammers have three settings: drill mode, hammer drill or just hammer, so they can act as a mini jackhammer.
Compared to less advanced power units known as hammer drills, rotary hammers tend to be larger and provide a bigger impact force by utilizing a technology called the "electro-pneumatic" (EP) hammering mechanism, because it is powered directly by electricity instead of a separate air compressor.
Rotary hammers have two pistons – a drive piston, and a flying piston. An electric motor turns a crank, which moves the drive piston back and forth in a cylinder. The flying piston is at the other end of the same cylinder. The pistons do not actually touch, but the air pressure in the EP cylinder allows for a much more efficient transfer of hammering energy than springs in the cam-action style hammer drills.
The majority of modern rotary hammers as well as all electric-powered chipping guns or jack-hammers all utilize this EP technology.
Features
Quick change chuck allowing you to change quickly between masonry and steel bits.
Dual LED Job light for enhanced visibility in low light & confined conditions.
Onboard dust extraction can be fitted as an accessory for dust extraction without a separate vacuum.
XPT - Extreme Protection Technology that protects against dust & moisture even in the harshest jobsite conditions.
Select between 3 Modes: Rotation only, Hammer only & Rotation with Hammer.
AVT - Anti-Vibration technology delivers unbelievably smooth performance at just 9.5m/s² thanks to the counter weight mechanism and vibration absorbing handle.
AFT - Active Feedback-sensing Technology prevents kickback for added safety.
Comes WITHOUT BATTERY & CHARGER.
Variable Speed Dial allows the user to adjust the speed based on application.
18V x 2 Brushless Motor provides efficient energy production and more power, lower heat production and increased work on a single charge.
Benefits
BL Motor & AVT + SOFT NO LOAD Functions Deliver High Power and Low Vibration.
18V solution for corded power demands.
Two 18V LXT Li-Ion batteries deliver the power and run time for corded demands without leaving the 18V LXT platform.
Constant speed control automatically applies additional power to the motor to maintain speed under load.
Torque limiter stops rotation if bit jams for increased operator safety and enhanced motor protection.
AWS - Auto-Start Wireless System, allows the tool and compatible vacuum to run automatically while the switch trigger is being pulled.
