Why not hammer drill iron
Motor protection device: comprehensive in use will inevitably have hard granular access to a machine (especially on the machine to work on drilling, such as drilling on the top wall), if there is no certain motor protection, rotating at high speed can easily be hard break or scratch enameled wire, eventually lead to the motor failure.
Positive function: can make use of a wider range of electric hammer drill, the form is mainly realized through switch or adjust the brush position, usually big tools will be used to adjust the brush position (rotating brush) to achieve the benefits of doing so is easy to operate, effectively inhibit the spark to protect the commutator, prolongs the service life of the motor6, hammer drill double function: both the impact hammer, electric drill and penetration.
The characteristics of the electric hammer drill:1, a good shock absorber system: allows the operator to hold comfort, relieve fatigue.The way to realize is realized by vibration control system;Through the soft handle increased comfort grip;2 、 accurate speed control switch: when the touch switch is lower, it can help the machine to drill smoothly (for example, drilling on the smooth surface of tile, not only prevents the drill from slipping, but also prevents the hole from breaking. High speed can be used during normal work to ensure efficiency.3, stable and reliable safety clutch: also known as the torque limiting clutch, avoid large torque during use due to seizure caused by the reaction of bit transfer to the user, this is a kind of safety protection of users. This feature also prevents the gears and motors from stopping rotating.
Electric hammer drill (electric hammer drill), is the "two function drill" and "hammer" handheld electric tool, "rotary cutting drill", with the impact of the impact mechanism of driving impact drill bit, drill driven in rotation at the same time, there is a direction perpendicular to the rotation of the rotary drill the reciprocating motion of the hammer. For concrete, brick, tile, marble and other materials drilling. "Hammer" to drive the impact force of drill rod, used for concrete, bricks and other materials on the slotting, holes or broken concrete etc..
Not because the iron hammer drill drill iron hammer drill bit hardness is greater than the capacity of.
