Lithium Hammer FCC Certification Cycle and Costs

Lithium electric hammer FCC certification cycle and cost. Exporting lithium electric hammers to the United States requires FCC certification. The electric hammer is an electric rotary hammer drill with a safety clutch and a pneumatic hammer mechanism. The electric hammer utilizes the principle of piston motion to compress gas and impact the drill bit. It does not require much force from hand and can drill holes of 6-100mm on hard materials such as concrete, bricks, and stones. The electric hammer has a higher efficiency in drilling on these materials, but it cannot drill holes on metal.

Electric hammer is a widely used electric tool. Electric hammer is a piston driven by an electric motor with a crankshaft connecting rod, which is added to the electric drill. It compresses air in a cylinder to and fro, causing periodic changes in air pressure inside the cylinder. The changing air pressure drives ****** in the cylinder to hit the top of the drill bit back and forth, which is equivalent to hitting the drill bit with a hammer. Hence the name electric hammer.

Electric hammer is a type of electric drill mainly used for drilling holes in concrete, floor slabs, brick walls, and stone. Specializing in drilling holes on walls, concrete, and stone, as well as multifunctional electric hammers that can be adjusted to the appropriate position and equipped with appropriate drill bits to replace ordinary electric drills and pickaxes.

Due to the rapid reciprocating motion (frequent impact) along the direction of the electric drill rod while the drill bit of the electric hammer rotates, it can quickly drill holes in brittle materials such as cement concrete and stone. A high-end electric hammer can use a conversion switch to put the drill bit of the hammer in different working states, that is, only rotating without impact, only impacting without rotating, both impacting and rotating.

The principle of electric hammer is that the transmission mechanism drives the drill bit to rotate while also having a reciprocating hammer movement perpendicular to the rotating head. An electric hammer is a piston driven by a transmission mechanism that compresses air back and forth in a cylinder. The periodic changes in air pressure inside the cylinder drive ****** to hit the top of the brick back and forth, as if we were using a hammer to strike the brick, hence the name electric hammer.
