The difference between using the impact drill and hammer

Post Time: 2016-07-13

Impact drill is a power tool and rotating both with shocks. It comes with an adjustable mechanism, when the adjustment ring is rotated in the non-impact position, fitted with a metal twist drill in drilling. When the adjustment ring in the rotational position of the belt and the impact on the placement with carbide drill bit can drill holes in brick, concrete walls, roof, and the scene.

Usually only drill with rotary manner, particularly suited to the needs of a small force of drilling materials, such as cork, metal, brick, tile, etc., while the impact drill is versatile, as they can either use the "single drill" mode, You can use the "impact drilling" mode, so it-yourselfers and professionals, it is worth choosing basic power tools.

Impact drill works by rotating and impact to rely on work to produce a continuous force, and a single impact is very slight, to BOSCH best sellers GSB13RE example, every minute impact frequency of 44800 times to produce a continuous impact. Therefore, the hammer drill can be used for drilling on natural stone or concrete.

Hammer rely rotation and beat to work. Single beat power is very high, and have a higher beat frequency to BOSCH best sellers GBH2-22RE example, load hammering frequency 4400 times a minute, a single impact force of 2.2 joules per minute so that each can produce significant force. Compared with the hammer, impact drill requires more pressure to drill into hard materials, so when drilling in stone and concrete, in particular relatively hard concrete, hammer should be used. Some hammer drill and impact on the shape difference is not obvious, it should be in the purchase of the technical parameters of the difference.

Impact drill under normal circumstances can not be used as a drill used: first, because the impact of drilling in the use of direction is not easy to grasp, prone to misuse, the opening is too large; second is to drill is not sharp, so that the open hole is not neat, burrs or cracks appear; Third, even above a switch, but also try not to drill, unless you use special wood drill bit, but due to the speed of the drill quickly, it is easy to drill holes at the black and fever, thus affecting the life of the drill.
