A laser tool is designed to indicate and align measurements, preferably holes to be drilled for hangers that support plumbing and electrical piping, without the need for the use of a tape measure. The laser tool contains an angled base with magnets that allow the tool to remain steady on a pipe. Also included in the base is a bubble level, indicating and allowing the user to balance the tool in relation to the pipe. The laser of the tool is connected to the base by means of a swivel device, so that the user is capable of moving the laser at an angle to obtain additional measurements that are level and aligned with the original measurement for a hole.
