HI-MAX IC-054 with a hex holder of 17 mm with convenient depth. The device ensures a no-load speed of 3600 RPM for valid and predictable output. The IC-054 is commonly used in the construction field and it is the most strengthened but convenient machine. This effective tool is beneficial in taking down massive concrete structures. The strong electric motor, with an operating wattage of 1100-watts, utilizes a bit that beats vigorously on the concrete surface until it disintegrates.
