With the advancement in technology and in this modern world where every machine is automatic, we still need some skills and techniques as how to use some regular machines. Today, I will be discussing some effective steps to inform you of how to properly use a “hole saw.”
A hole saw is a ring-shaped annular structure used to cut different materials. Now the circular structure of the saw helps to cut round holes in whatever material it is being used on. It is used in conjunction with the drill.
Techniques for Using Hole Saw
I will try to elaborate on the techniques for using the hole saw, step by step, to have a clearer view of the required procedure to ensure successful usage of the saw.
The Correct Size of Hole Saw
The first and utmost important thing is the size of the hole saw. Normally when we use a hole saw for cutting holes in a wood or plastic we do not require any lubricating oil since the material in question is soft enough to be cut.
But while using a hole saw over a metal, to ensure smooth cutting of the hole saw, lubricating oil must be used.
Selection of Arbor
The selection of arbor depends on the power drill with which it is used. Moreover, the diameter of the hole that is to be made also finalizes our choices for the type of arbor to be selected.
Insertion And Tightening of Arbor onto The Saw
Now, after the selection of arbor, it is mounted on the back of the hole saw. Rotate the arbor until you reach the preferred tightness. It is to be made sure, that the arbor extends beyond 3/8 inches of the toothed end of the saw.
Boring a Pilot Hole
Firstly, a point is marked on the surface where the hole is to be made. After that, drill a pilot hole 1/8 inches deep. The hole saw wanders over the surface until a hole is made. Therefore, a pilot hole is bored to maintain the hole saw in a centered position.
Placing Hole Saw in The Pilot Hole
The hole saw is brought in contact with the pilot hole by holding the drill in both the hands. To avoid any uneven movement, the teeth of the hole saw are made to touch the surface evenly. The speed of the drill should not be very fast in the beginning. Rather, it should be increased gradually.
One thing to keep in mind is that you will have to let the drill to slow down before stopping it. After that, it has to be lifted out of the hole. The purpose of this would be to clear all the dust and to cool the drill down.
Unplugging The Hole Disc From The Surface
The first method employed to remove the hole saw from the material are done through plug-ejecting devices. But the problem with these devices is that they are not easily available and are tedious to be dealt with.
The second method is to drill some inches extra. This will give enough space to the hole saw to be extracted out.
Removing The Hole Saw/Disc From The Drill
To remove the hole saw from the drill, the power supply of the drill has to be stopped at first. Then with the help of a screwdriver, the hole saw is removed.
Removing The Dust From The Hole Saw
In the end, the hole saw has to be cleaned from any sort of residuals. If the arbor has an ejector spring, it will be easy for the residuals to just rinse off the hole saw the moment it is withdrawn from the workpiece.
Some Safety Measures While Using A Hole Saw
- While cutting the surface, the pressure should be kept minimal.
- The hole saw shouldn’t be continuously used without lifting the saw out of the holes. This will ultimately result in raising the temperature of the hole saw thus eventually damaging it. The hole saw should be lifted in between to cool it down.
- Lubricating oils must be used to ensure a smooth cutting process.
- The blades of the hole saw should be sharpened enough to avoid any uneven holes.
The Experience of Using A Hole Saw
The advantages of using a hole saw are that, whatever little amount of material that is needed to be cut, is efficiently removed with the minimum usage of power/energy. And hence, it helps in an economical cutting of any material.
Moreover, there are always variables sizes of hole saw which helps us to cut holes of different sizes.
Main disadvantages of using a hole saw is that very often hole saw get stuck within the surface, mainly due to the accumulation of the dust within the hole. This could be avoided using lubricants. Moreover, once the process of cutting is done, the residuals remain within the blades which slows down the efficiency.
From the discussion above, it can be concluded that hole saw is an efficient device used to cut down materials ranging from something as soft as plastic to hard materials like steel, etc.
The only thing that is to be given the utmost importance is that one should be fully aware of the techniques for using hole saws. Only practice and acquisition of skills might ensure a smooth cutting process with the help of a hole saw.
