Hex Shank Fully Ground Turbomax Drill Bit for Metal etc

Impact drills can be used for natural stone or concrete. They are universal, because they can use either the "single drill" mode or the "impact drill" mode, so they are basic electric tools worth choosing for professionals and hands-on workers. The electric hammer works by rotation and hammering. The single hammering force is very high and has a hammering frequency of 1000 to 3000 per minute, which can produce significant force.

Compared with impact drills, electric hammers require minimal pressure to drill into hard materials, such as stone and concrete; Especially relatively hard concrete. The electric drill only has a rotation mode, which is especially suitable for drilling holes on materials requiring very little force, such as cork, metal, brick, ceramic tile, etc. The percussion drill works by rotation and impact. A single impact is very slight, but the impact frequency of 40000 times per minute can produce continuous force.
