Similarities and Differences between Electric Drill, Hammer Drill and Impact Drill(b)

Post Time: 2016-07-17

The difference between the hammer and drill
The essential difference between hammers and drills are: (1) the volume of sample sizes. (2) component of course is not the same. Drill inside only
An electric motor (rotor + stator) and the gear biting each other and some number of revolutions, the hammer is not the same, shall be called the "hammer" so it has impact
, Can be drilled concrete, stone and other hard materials. So the volume is larger than the hammer drill bit, we should hammer inside the cylinder, connecting rod
Piston and other important accessories. The drill can drill wood, metal, plastic and other materials.
Hammer piston movement is the use of compressed gas impact drill, no hand so much effort, the material can be rigid in concrete bricks, stones, etc.
On the opening hole 6--100mm, the hammer on the above-mentioned high feed openings fiscal efficiency, but it does not work on metal hole. Impact drill is not needed manpower
Put pressure on the metal, wood and other materials hole diameter 6-50mm. The advantage is vibration, high precision openings, price is not high. Also they use
The drill bit are not the same, the former is set with the bit of the alloy, which is a common cutter bits.
Hammer and impact drills are openings in the concrete structure.
Both have the function of the piston movement,
Hammer as suitable for large-caliber 30MM above. The advantages of high efficiency, large aperture, drilling depth length. The disadvantage is that vibrations on the surrounding structures have
Some degree of damage.
About 25MM impact drill suitable for drilling small diameter and short depth and other conditions. Such as installing expansion bolts. Damaging effects on the surrounding structures
Very small.
In addition to air conditioning installation is appropriate hammer outside the hole through the wall. Other locations should drill.
the difference;
Hammer drill with lock clip-on assembly, simple, without any tools.
Impact drill requires a dedicated key tighten.
