Hole Saw Kits. Sometimes you need to have a large hole more remarkable than 1-1/2-inches. The best tool to finish the job is using a hole saw.
What are hole saw kits?
You can utilize hole saw kits to cut round holes. An excellent bi-metal hole saw can cut through materials, including plastic and wood items.
Hole saw kits can also cut perfectly round holes through steel and stainless steel. The high-speed steel hole saw kits would determine its performance.
If drill bits have limited diameters to drill, hole saw kits can drill through a broader diameter. Hole saw kits are much more efficient than a spade drill or twist drill.
Hole saw kits are designed to be mounted or attached to a power drill and rotate at high speed to perform a cut. As the saw of the kit spins, the teeth cut into the material, removing a slug.
The common application of hole saw kits
- Locks or deadbolts can be installed using hole saw kits on doors
- Installing fitting or light fixtures need to have holes in the ceilings. This is where you use hole saw kits
- Hole saw kits can cut holes for accommodating waste pipes or drainage
- You can utilize hole saw kits to make extra or new connections in pre-existing pipework
- Cutting vents in masonry
- Hole saw kits can cut holes for wires or cables
- Making birdhouses
Components of hole saw
1. The body
The body of a hole saw is a metal cylinder. Its body is made of steel as the standard material to make hole saw kits.
The cylinder is mounted or attached to an arbor. To facilitate the ejection of chips and dust, slots cut into its walls. This motion is to prevent stuck blades and make sure smooth performance.
The number of slots varies between models. Six slots are generally the upper limit and the optimum strength.
The hole saw the metal or steel cylinder reaching the highest point with an edge that utilizes ultra-hard embedded materials, serrated saw teeth, and square teeth to cut through your workpiece.
a. The cutting blade
Serrated saw teeth
These saw teeth are commonly set at a 60° angle. The setting will help deliver a sharp or penetrating bite into the material being cut.
It is the most common cutting edge. You can use this type of saw teeth for plastic, softer metal, wood, and plaster.
Coated hole saws
The hole saw does not have teeth. The cutting edge of the kit is coated with diamond or tungsten carbide.
You can use these coated hole saws to cut through concrete, ceramics, and heavy-duty metals. Professionals use this type of hole saw.
To finish fine cuts, you need to use square tooth hole saws for abrasive surfaces, such as stone, glass, concrete, brickwork, and ceramic tiles.
b. The pitch
The pitch means the distance between two teeth (serrated) or the middle of two square teeth. A variable pitch hole saw differs that distance. A constant pitch hole saw have the same distance.
A variable pitch hole saw breaks the sawing rhythm that limits vibration. By limiting vibration, you can finish the cuts with a lower noise level, a smoother cut, and reduced blade wear.
Sawdust and chips get out easily to lower the risk of overheating or clogging.
A constant pitch hole saw operates slower but will produce a much more good cut.
c. The TPI
The TPI is a measurement of tooth frequency along the blade. 10 TPI means ten teeth per inch. TPI numbers vary, but they stay within 20 to 2.
Higher TPI blades will cut slowly, cut smoothly. Lower TPI blades cut faster, tend to tear at fibers, and produce a ragged edge.
2. The arbor
The arbor is an essential part of the hole saw. Arbor will grip other moving tool components or connect the power drill, and hole saw.
When you purchase a hole saw kit, pay attention to whether it is equipped with an arbor or not. You might have to purchase one if not included.
The best arbor is the one with a spring or known as ejector spring, placed over the drill bit. The ejector spring contract as you operate the drill and then eject the slug after the hole has been created.
There are fixed or detachable arbors and small or large arbors.
a. Detachable arbors
This means that arbors are detachable to the hole saw and can be used with different blades. Having detachable arbors will eliminate the need to buy one for every hole.
b. Fix arbors
The fixed arbors are attached or mounted to the hole saw blade. You can not dismantle it when you require to change the saw size.
c. Small arbors
Shank size: 1/3-inch or 8.75mm. Diameters: 14mm – 30mm or 1/2 – 1 inch.
d. Large arbors
Shank size: 7/16-inch or 11.1mm. Diameters: 32mm – 210mm or 1 – 8 inches.
3. The drill bit
You can see a drill bit located at the center of the hole saw. A drill bit can create a pilot hole to anchor the hole saw in its place.
There is a blunt hexagonal shank located at the other end of the drill bit. It is gripped by and inserted into the power drill’s chuck.
Benefits of using hole saw kits
Hole saw kits can support the achievement of a much more variation of hole sizes. A hole saw can cut large diameter holes.
Because the total quantity of material being eliminated is small, it would need less power. This what makes a hole saw more efficient compared to a conventional drill bit.
3. Reduce friction
A solid drill bit may cause friction during the drilling. Since the cylinder walls of the hole saw are thin, it can cut through material with less friction.
Less friction means less power is needed. Cutting time is reduced, save on energy and battery life.
4. No cut core
When working on larger holes, a hole saw does not need to cut up your material’s core. This is a significant advantage compared to spade drills or twist drills.
Factors to consider when purchasing hole saw kits
Manufacturer warranties are needed to protect a tool during a crucial period of time. A hole saw may break due to a defect in the design or a failure on a battery or the mechanized or electrical part.
It would be best if you remembered that it is in your best interest to register your hole saw after you purchase it. Always keep the receipt somewhere safe should you need to have your hole saw repaired under warranty.
The manufacturers will need you to provide proof of the date of purchase. They want to know if it is under their warranty policies. Some brands provide two years warranty, and some support a 3-year warranty.
- Carbon steel. A carbon steel hole saws work well for cutting wood or soft materials. It can not work on more abrasive materials such as metal. They are light-duty and used only on plasterboard, non-laminated plastics, and wood. The price is low and suitable for infrequent usage.
- Bi-metallic high-speed steel. If you want to cut or make holes frequently, the best to use is the bi-metallic high-speed steel hole saws. They are also best for multi-purpose use. Bimetallic teeth hole saw can cut through wood and metal. It is durable and hard. Used for sawing holes in wood, cast iron, aluminum, brass, and plastic.
- Tungsten/silicon carbide. Material such as ceramic tiles, fiberglass, metal, and plywood are abrasive materials that can be cut using hole saws with teeth that have been tipped with silicon carbide or have a carbide grit or tungsten. They are powerful and hard to cut material.
- Diamond edged. Diamond edged hole saws are heavy-duty tools for heavy-duty applications, including cutting into concrete, brickwork, and masonry.
You do not need a huge collection of hole saws if you are repeatedly cutting the same size holes. You need to purchase a particularly better quality hole cutter.
Investing huge selection of hole saw kits is very useful if you are cutting many different size holes. It will save you money and support you with different the size of the hole as needed.
The drill bits
A short drill bit cab provides stability and less flexibility to cut harder materials. While the long drill bit is beneficial at anchoring the hole saw to the material.

How to care and maintain hole saw
It would be best if you find the right place to store your hole saw kits. Find a secure and dry place.
The right location will reduce the risk of being corroded or damaged by harmful elements. Keep them out of reach of children. Always keep them in their box.
Inspect your hole saw for wear and tear. It would be best if you keep the hole saw in its prime condition for further use.
Due to the amount of friction and wear, a hole saw needs replacing sometimes. A cut may get rough when the hole saw is not in good shape.
Replacing a dulled hole saw is the fastest way to get it in excellent condition. Sharpening a hole saw is time-consuming.
You can use a hand file to sharpen each tooth. The best tool is the one made from diamond.
For a faster process, you can use a hand-held electric grinder. It is quicker but needs concentration.
A bench grinder can also finish the job. All you have to do is to angle the teeth into the grinding wheel. Sometimes you cannot sharpen the teeth because it would be impractical or impossible to sharpen them with excellent results.
Every time you cut metals, it is recommended to use high-quality cutting oil. This practice will help assist with removing and clearing chips.
In the end, you will achieve a smoother cutting action and creates less friction. Keeping the hole saw cooler would extend the working life of the hole saw.
It is recommended to apply even pressure and ensure the teeth engage with the material evenly. All of this will help prevent tooth getting stripped and reduce erratic sawing action.
If you are willing to extend the life of your hole saw, you will avoid a costly mistake. It is recommended that you clean the hole saw from dust, debris, chippings after every use.
Dust, debris, or chipping may become stuck or even damaging the teeth. Use a toothbrush or paintbrush and clean the hole saw carefully, and make sure there are no left behind.
Since you are working a hole saw, there is a chance that injury may occur. It is a vital requirement when using a hole saw.
You need to wear safety wear and employ the safety equipment. Make sure to wear eye protection and a face mask or mouthguard. These pieces of equipment will prevent splinter or dust from getting inhale or get into your eyes.
Other safety requirements are safety gloves and ear protection to safeguard your hearing. You are well-advised to use the drill that comes with a side-handle to support stability and control.
How to use a hole saw
1. Wear safety equipment
You must wear your safety equipment every time you want to start making holes.
2. Drill a pilot hole
Drilling a pilot hole will be used to guide the saw. The pilot drill goes to the center where you wish to cut.
3. Insert the hole saw
Use a chuck key to tighten the arbor into the drill. Ensure that no movement in the chuck means the hole saw is secure. Inspect if the hole saw is straight. Keep the position off-center or drilled at an angle.
4. Aligning the drill bit
After you are finished making the pilot hole, the next thing to do is arbor’s drill bit alignment. Inspect and make sure that the teeth are all in even contact with the material.
You need to add oil when you are cutting metal material or lubricant over the blade before starting.
5. Keep the drill steady
You must be patient and start the drilling slowly. Hold the grill firmly.
You can start squeezing the trigger gently. Do not push the saw hard, and you must focus on keeping the hole saw level.
6. Remove chippings and dust
In a few moments, stop the drilling and clear any dust, debris, or chippings. So you can back the drilling with a clean hole. Removing dust or debris will avoid overheating or clogging.
7. Clean the hole saw
To maintain the hole saw, make sure you clean it with a toothbrush so it is free of dust and debris.
