Advanced Drilling Techniques
Drilling at an Angle
Drilling at an angle, also known as angled drilling, is a technique used to provide access to hard-to-reach or awkward locations. This method of drilling involves using a special drill bit and guide that allow the user to drill at varying angles. The most typical angle for angled drilling is 45 degrees, but depending on the application may require other angles such as 30 or 60 degrees. To ensure accuracy when drilling at an angle, it is important to use a jig or template to mark the desired path prior to beginning the job.
Reverse Drilling
Reverse drilling is a unique technique used in situations where traditional drilling would not be feasible due to limited access. In reverse drilling, the direction of rotation of the drill bit is reversed, so that it spins in a clockwise direction instead of counterclockwise. This method is most commonly used when drilling into concrete or masonry where the structural integrity of the material would be compromised if traditional drilling methods were used. Reverse drilling can also be used to prevent damage to delicate materials such as thin sheet metal or certain plastics. It provides a much cleaner cut than traditional drilling since there is less torque applied to the material being drilled.
Drilling Larger Holes for Plumbing or Electrical Installations
In order for plumbing or electrical installations to be properly performed, it is often necessary to drill holes that are larger than what can be achieved with conventional drilling techniques. This type of job usually requires the use of diamond core drills, which are capable of producing much larger and more precise holes than traditional drill bits.
