Compared with less advanced hammer drill power devices, by using a technology called the "Electro-Pneumatic" (EP) hammering mechanism, BISON rotary hammers tend to be larger and provide greater impact force because it is directly driven by electricity and Not a separate air compressor.
BISON rotary hammer generates an impact through the piston-driven by the crankshaft. The piston is located in the cylinder and generates air pressure when driving forward, and it is the air pressure that actually drives the hammer mechanism. BISON rotary hammers provide more impact energy than hammer drills. They are more durable and are the tools of choice for professionals. Another big advantage is that most rotary hammers have three settings: drilling mode, hammer drill, or hammer only, so they can act as mini jackhammers.

A: A rotary hammer is a powerful tool that can perform heavy tasks such as drilling and chiseling hard materials. It is similar to a hammer drill in that it also knocks the drill in and out as it rotates. However, the rotary hammer uses a piston mechanism instead of a special clutch.
A: A drill with a brushless motor adjusts its speed, torque, and power supply to match the task at hand. It'll sense if you're driving screws into a light material like drywall or a dense material like mahogany, and use only enough power to accomplish the job.
