Both drilling and boring machining processes create holes in solid materials. Drilling is typically used to make small or medium-sized holes, while boring is used to create larger holes. Both drilling and boring can be done by hand or using a machine. Drilling is often done using a hand drill, while boring is typically done using a machine such as a lathe or milling machine.
What Is Drilling?
Drilling is a cutting process that uses a drill bit to cut a hole in a circular cross-section in solid materials. The drill bit is usually rotated at high speeds (about 1200 rpm) when fed into the work piece. Drilling generally produces round holes with smooth surfaces.
What Is Boring?
Boring is a machining process that enlarges a pre-existing hole in a workpiece. It can be performed using various tools, such as boring bars, hand drills, or lathes. Boring produces smooth, round holes with accurate
Drilling Vs. Boring
Drilling and boring are both used to create holes in solid materials. There are many differences between both. Few of them are below:
- Process: The main difference between drilling and boring is that drilling is a process of making a hole using a drill bit, while boring is enlarging an existing hole.
- Size: Drilling is typically used to create small or medium-sized holes, while boring is used to create larger holes.
- Tools: Drilling involves using a drill bit, a cutting tool with sharp teeth that helps to make the hole. The drill bit is attached to a drill, a power tool that turns the bit and cuts through the material. Boring, however, does not involve using a drill bit. Instead, it uses a boring tool, which is a cutting tool with a single point that is inserted into the existing hole. The boring tool is then turned to enlarge the hole.
- Hand vs machine: Both drilling and boring can be done by hand or using a machine. Drilling is often done using a hand drill, while boring is typically done using a machine such as a lathe or milling machine.
- Smoothness: Boring results in a smoother surface finish than drilling. Drilling creates holes, while boring is used to enlarge existing holes.
- Speed: Drilling is typically done at high speeds, while boring is usually done at lower rates.
Boring Tools
Boring tools are designed to enlarge or finish a hole that has already been drilled. The most common type of boring tool is the drill bit. Drill bits come in various sizes and shapes and can be used to drill wood and metal.
Boring Methods
- Trepanning: Trepanning is done with a hand drill or a power drill. A hole is drilled into the workpiece, and then a trepan is used to remove the material from the hole. The trepan has a cutting edge that resembles a saw blade, and as it cuts, it removes the material in chips.
- Blind boring: Blind boring is done with a hand drill or a power drill. A hole is drilled into the workpiece, and then a reamer is used to remove the material from the hole. The reamer has a cutting edge that resembles a saw blade, and as it cuts, it removes the material in chips.
- Counter-boring: Counter-boring is done with a hand drill or a power drill. A hole is drilled into the workpiece, and then a counter-bore is used to remove the material from the hole.
Drilling Tools
Many different types of drilling methods and tools are available on the market today. The most common type of drilling is using a hand drill, a simple tool consisting of a handle and a drill bit. This type of drill is perfect for small projects such as drilling holes in wood or metal.
Drilling Methods
There are three main methods of drilling:
- Manual drilling: Manual drilling is the most common type of drilling and is used for shallow holes. It is a slow process and requires a lot of physical effort.
- Machine drilling: Machine drilling is faster than manual drilling and is used for deep holes.
- Percussion drilling: Percussion drilling is the quickest type and is used for very deep holes. This type of drilling produces a lot of noise and vibration. It is also the most expensive type of drilling.
FAQs
What is the difference between rotary drilling and motor drilling?
Rotary drilling is where the drill bit is rotated to create a hole, while motor drilling is where the drill bit is moved back and forth to create a spot.
Conclusion
In drilling, a cutting tool is used to make a hole in the work piece, while in boring; a rotating tool is used to enlarge an existing hole. Drilling is performed using a drill bit, while boring is done with a boring bar. Drilling can be done on horizontal and vertical surfaces, while boring is limited to flat surfaces. Drilling is a faster process than boring.
