A hole saw is also known by another name. It is also called a core drill. And a masonry hole saw is used to drill holes in concrete, walls, and bricks. The hole is made by electric hammers that acts like a boring tool that can make very large holes. But the hole size is as much as the cup shape of the saw.
A masonry hole saw has a blade that is round in shape or has a ring-like shape. When it cuts holes in masonry work, the chunk that is drilled is also round in shape. It does not cut the innermost part of the material. They are used typically in drills to make holes. There are bearings which help in the up and down movement of the saw, so that the right hole measurement can be achieved.
The Construction of the Hole Saw
The masonry hole saw is basically a metal cylinder. The metal is steel, and it is placed on the arbour. The edge that cuts the hole in the wall is fitted with saw teeth or industrial diamonds that are placed in it. The arbour also has a drill bit to make a centering hole.
As the masonry hole saw cuts a few millimeters into the concrete, the centering mechanism will not be required. Although it is not required, yet it helps in making a perfect hole in the masonry work. This saw can be used to drill a hole into marble, and the bit can also be secured in a place by turning the screw in roundabout direction located on the arbor, with the help of a screwdriver.
Types of Hole Saws
There are Two Types of Masonry Hole Saws. One is The Adjustable Type, and the other is The Circle Cutter Type:
1. Adjustable Type: This type of masonry hole saw has numerous metal blade-like strips that are very thin. It has flat discs that have many grooves on one side and a shank on the other side. When you snap the blades into various grooves present on the disc, different sizes can be made. Hand tool kits and power drills are also made as a part of using the masonry hole saw for any minor or major tool-using activity.
2. Circle Cutter: This is a variation of the adjustable type of saw. It can have 1-3 teeth that are adjustable, and this is made on the platform that has the pilot bit. This masonry hole saw is used in cutting holes of large sizes.
Different Parts of A Hole Saw
The masonry hole saw has many different parts or components. They comprise teeth for cutting, slots, pilot drill and arbour. The teeth have a pitch that is either constant or changes and they are generally set at an angle of 60 degrees so that they can cut easily through.
You can say variable speed in masonry saw hole, when the teeth have variable distance between each other, and this makes the cut smooth and does not wear out the blade.
The Benefits of Masonry Hole Saws
The advantage of a masonry hole saw is that they are highly efficient. It is so because it cuts very little material that needs to be discarded away.
Conclusion
Drilling holes into masonry work becomes very easy with the presence of masonry hole saws, but for that, you must be very careful about the power of your drill machine. And whatever be the power of your drill, make sure that you are in the proper gear for your own safety that must be taken into consideration before you start utilizing the masonry hole saw.
