Drills for concrete are tools used on materials such as concrete, tile, and stone. It is difficult to cut through gravel and rocks in concrete by rotation alone, so vibration and impact are applied vertically to the perforation direction in order to drill holes while pulverizing material. When performing work, electric impact drills or hammer drills for concrete perforation are used. Shank shape includes straight, SDS-plus, SDS-max, and hexagonal shanks, so select a shank shape that fits the electric machine. When drilling pilot holes for anchor installation using drills for concrete, hole distortion and diameter reduce efficiency and strength of anchor installation, so it is important to select a drill of the appropriate diameter, length and application.
