When the hole saw is installed on the ordinary electric drill, it can easily cut round holes, square holes, triangular holes, straight lines and curves on the plane, spherical surface and other arbitrary surfaces of various plates such as copper, iron, stainless steel and organic glass.
Generally speaking, woodworking hole saws are installed on electric hand drills or bench drills. Electric hand drill is more affordable, but it needs higher technology to grasp the opening angle. Bench drill is more expensive, and the holes drilled are more standard.
Bimetallic hole saw can also be used to open wood. Hole saw with large diameter cannot be drilled by hand electric drill, which is easy to break the wood board and even burn the machine. Large caliber will use bench drill or engraving machine.
There is a diamond stone on the head of the glass opener, which is hard enough to grind through the glass. If it is ordinary glass, you can use a glass hole saw, but not tempered glass.
In addition, the glass hole saw can also be used to grind hand beads.
The glass hole saw can also be used to open ceramic tiles. When making ceramic tiles with a hole saw, drill while adding water. In this way, the loss of drill bit will be not too fast.
There is diamond on the rotating head of marble hole saw, which can open marble with high hardness.
The diamond on the head of the glass hole saw is finer than that of the marble hole saw. It is easy to bounce edges and appear rough to hit glass with marble hole saw. If you hit marble with glass hole saw, it will be laborious. If the quality is average, you can’t punch a few holes.
There are many kinds of bimetallic hole saw. Now on the market, there are ordinary type, specially used on thin iron sheet; practical type, specially used on thin stainless steel; medium-grade type, specially used on stainless steel; high-grade type, specially used on stainless steel (the thickness of steel plate can reach more than 2cm). The usage of high speed steel hole saw is similar to that of alloy hole saw. The difference is that the alloy hole saw is suitable for punching steel plates. High speed steel hole opener is suitable for drilling steel pipe.
Alloy hole opener can open stainless steel, 20mm iron sheet and various steels with high hardness.
Bimetallic hole opener is made of the world’s most advanced electron beam welding and then vacuum high-temperature quenching. Its tooth shape is sharp and durable, the blade is not easy to fall off and has high stability. It is widely used in industrial cast steel, castings, automotive aluminum, engineering pipeline opening, iron plate opening, furniture wood opening, galvanized pipe, fire pipeline, plastic, wood, gypsum board and so on. The most common is that customers buy it to open the iron plate.
