A gun drill machine usually comes in the form of a gun with a trigger that controls the speed and power of the drilling bit. When I first looked at it, I immediately thought of it as a dangerous tool. However, I realized that it is actually a safe tool to use after I understood how the tool works.
Understanding Gun Drilling
Gun drilling is a more modern take in creating holes than the traditional twist drills. Unlike twist drills, the unique geometrical head has a cutting edge and guiding pad. The guiding pad polishes the inside of the hole to get a cleaner cut. Without the pad, the tool will cut less accurately and result to a crooked hole. Coolants are also introduced through a hole within the drilling shaft. It prevents the drill from overheating while keeping debris out at the same time.
Types Of Gun Drill Machine
- Internal – The drill shaft for this type uses its hollow part as a passage where the excess materials can exit. The coolants flow from the outer part of the shaft to the front tip of the drill. This forces the chipped off material to the hole in the middle of the shaft.
- External – This kind of drill have grooves along the sides of the shaft. It is where the debris is deposited out from the hole. The coolant flows through a gap within the shaft and assists in bringing the debris out. I prefer this over the internal type and most people also seem to do so. The main reason for this is that it is easier to clean. We don’t have to remove the debris out from the hollow part of the shaft unlike with the internal type.
How To Properly Place The Drill Bits?
Drill bits are the attachments placed on the tip of the drilling gun. They come in different sizes and shapes which allow us to create unique holes. Before I install the bit, I make sure that nothing is wrong with it. I then place the dull part of the bit in the hole of the gun. The bit needs to be tightened and there are two ways to do this. One is to use a chuck key. This key comes in a shape that fits perfectly around the collar of the bit. When I use this, I simply insert the key to the hole on the collar and turn it around. The other way is too manually turn the collar. What I do is that I hold the outermost collar to immobile it and squeeze the trigger gently to spin the bit. For it to be tightened, the drill must turn clockwise. The spin of the drill can be easily changed with the switch near the trigger.
Where Can You Use A Gun Drill Machine?
The drill can be used in almost any surface. I use it on plastic, metal and even on wood and face no problem with it. Some people even use it on clarinets and other instruments.
All in all, I find this tool great for installing cabinets and drywalls. I use it on many DIY jobs and other tasks. Having a gun drill machine on my house helps me save time and effort when repairing or constructing things.
