What is a Hole Saw?

Hole saws are cylindrical-shaped saw blade attachments used with power drills to create perfectly round holes. When drilling big, deep holes or enlarging existing ones, they are much more efficient than flat or twist drill bits.

Some hole saws have diamond tips or made from more durable metals, so they can cut a cylindrical hole in marble, metal, wood, etc.

How to use a Hole Saw

Hole saws can be used for a variety of purposes. Some examples include installing drainage pipes and drilling holes for electrical wiring.

It is actually quite easy to use a hole saw once you have determined the size of hole you need to cut and chosen a hole saw that is appropriate for the material you are cutting. Here are our steps:

1. Insert the arbor through the back of the hole saw, so the drill bit and hole saw are facing the same way.
2. Secure the hole saw onto the arbors thread (usually by twisting it on the thread).
3. Tighten the arbor until it is secure in the drill chuck.
4. If your arbor does not come with a pilot drill bit, you may want to drill one yourself (although this is not required).
5. Prepare your hole saw for cutting by lining it up with the area that needs to be cut.
6. Drill slowly at first, and then increase the speed of the drill gradually.
7. Occasionally, back the hole saw out of the hole to remove dust.
8. Remove the waste material from your hole saw once you have successfully drilled your hole

That’s all there is to it. You should always use a power drill for hole cutting and wear appropriate personal protective equipment when drilling.

Note: If you’re cutting through a countertop and its marble, make sure to get the right hole saw and spray water on the cutting area. 

Parts of a Hole Saw

The hole saw consists of teeth, slots, and sometimes a pilot drill and arbor (as explained above).

The teeth are usually set at a 60° angle and either have a variable or constant pitch. The pitch of a variable pitch is determined by the distance between the teeth. As a result, the blade wears less and the cut is smoother. Constant pitch refers to a constant distance between two points. Although they cut a little slower than variable pitch, they make finer cuts.

There are different TPIs (teeth per inch) for hole saws. The higher the TPI, the slower the cut, but the smoother the finish. When the TPI is low, the cut will be faster, but it will be less smooth.

The higher the TPI, the less likely the hole saw is to tear your workpiece. This is more likely to happen at lower TPIs. A low TPI is defined as 1-4 teeth per inch, while a high TPI is defined as 10 or more teeth per inch.

Most hole saws have slots in their sides. The purpose of these vents is to allow chips and dust to escape.

Different types of hole saw kits

It is possible to find different types of hole saw kits on the market, and each type has its own benefits. Electricians prefer hole saw kits with a variety of sizes mainly cutting out downlights and making holes for wires in joists.

So just standard hole saws unless there is dry or wet drinking involved (stone or tiles).

Types:

Carbon Steel Hole Saws

Home improvement and DIY enthusiasts primarily use carbon steel hole saws for general-purpose use.

Used for 

Although they are less durable than bi metal hole saws, they are suitable for light duty applications. Only use them on plasterboard, non-laminated plastic, and wood. 

Variable Pitch Bi-Metallic Hole Saws

Hardened high-speed steel teeth are used in some hole saws manufactured from bi-metal material for fast, smooth cutting. Due to the fact that bi-metal hole saws will not shatter under constant use, they provide increased safety for the user.

Used for 

Among the materials they can cut are hardwood, chipboard, plywood, non-laminated plastics, plasterboard, and non-ferrous metals.

Variable Pitch Bi-Metallic Hole Saws (Deep Cut)

Designed for heavy-duty cutting, these hole saws are rugged and durable. They feature extra hard, variable pitch teeth for extended hole saw life and a cut depth of 42.5mm. Most variable speed power drills can be used with them.

Used for

You can use these hole saws on wood, metal, and hard plastics.

Constant Pitch Smooth Cut Hole Saws

High-speed steel is hardened, heat-resistant, and abrasion-resistant, and has constant tooth pitch. This hole saw’s hexagonal shank has a slight indentation. The indentation helps the shank lock into a drill’s chuck.

Used for

A wide variety of materials can be cut with them, including stainless steel, tool steel, mild steel sheeting, plasterboard, wood, and thin plastics.

Tungsten Carbide Tipped Hole Saws

Fast cutting action and long life can be achieved with hole saws with tungsten carbide teeth.

Used for

From construction engineers to DIY enthusiasts, these saws are perfect for multi-purpose applications. It is capable of cutting woods (including hardwoods), nonferrous metals, plastics, and tiles.

Gulleted Tungsten Silicon/Carbide Grit Hole Saws

With gulleted square teeth coated in tungsten carbide or silicon carbide grit, these hole saws can cut through hard and abrasive materials quickly. Their square teeth do not bite into the material like curved saw teeth. Therefore, they can cut through harder materials (such as ceramics or glass) without shattering them. 

Used for

Among the materials they can cut are brick, fibreglass, slate, marble, cement board, laminated plastics, plywood, and cast iron. In spite of the fact that these hole saws can be used on wood, standard shaped saw teeth are much more efficient.

Welded Shank Soffit Cutter Hole Saws

A non-detachable arbour is welded to the base of these hole saws. 

Used for

HSS (high speed steel) and variable tooth pitch make these hole saws ideal for cutting holes in plywood, metal, and PVC.

Diamond-Edged Hole Saws

For hardness and durability, some hole saws do not have teeth at all but are coated or infused with diamonds. Due to their high heat and wear resistance, they are very durable. Although these saws have a high heat resistance, it is recommended to quench them periodically in water to cool down the blades. Some of this type of hole saw can be fitted to any sized drill chuck without the need of an arbor.  

Used for

Typically, ceramic tiles are drilled with diamond-edged hole saws.

Multi-Hole Saw Set (7 piece)

There are multi-hole saw sets that are specifically designed for cutting holes of different diameters.

Used for

These hole saws can be used on a wide range of materials, including wood, chipboard, plywood, non-laminated plastics, plasterboard, and non-ferrous metals (except stainless steel).

Speciality Hole Saws

Despite their differences, the hole saws listed below are still considered hole saws. Other tools can also be used to cut holes in a given material.

Circular Tile Cutter with Tungsten Carbide Blade

There is a slight difference between the design of this type of hole cutter and the standard hole cutter. It has a sharp, straight, tungsten carbide blade attached to an arbour that rotates at high speed.

Used for

This blade can be adjusted and set at various distances from the centre point, allowing it to cut holes in a range of diameters. There is a safety cage surrounding its blade to reduce the risk of chips being expelled. Typically, it is used to cut ceramic tiles.

Tungsten Carbide Tipped Hole Cutter

Hole cutters have tungsten carbide tips instead of saw teeth, which create a cutting edge when rotated rapidly. The tool can be used with both mains-powered and battery-powered tools.

Used for

It can cut through wood, MDF, plastic, and ceramic tiles with ease.

Tungsten Carbide Tipped Core Drill Bits

When rotated at high speed, tungsten carbide tips ensure easy penetration with minimal effort. Don’t use a hammer drill as they will damage the bit.  

Used for

Rotary drill bits with tungsten carbide tips are used to drill through brickwork, stone, and concrete.

Diamond Core Drill Bits

Instead of pointed saw teeth, this type of hole saw has squared teeth embedded with industrial diamonds. Power drills equipped with a safety clutch and variable speed function should always be used with diamond core drill bits.

Used for

Hole saws with diamond core drill bits are suitable for cutting clean holes in brick and concrete. 

They are called core drill bits because they cut out a core of the material they are drilling through. The cutting teeth of diamond core drill bits can be damaged by hammer or impact drilling, so they should never be used with these methods. During use, diamond core drill bits don’t need to be cooled with water. 

Diamond Core Drill Bits (Wet/Dry Cutting)

The diamond core drill bits can be used wet or dry and will cut clean holes in most building materials. These batteries are ideal for use with hand-held power tools ranging from 800 to 1500 watts. To cut into masonry, these core drill bits require a drill with a high wattage.

Used for

You can use diamond core drill bits to cut holes in granite, concrete, brickwork, and stone.

What’s Wet Drilling?

While drilling holes in masonry (stone, concrete, brickwork), some core drill bits need to be quenched with water. The reason for this is that cutting into dense materials like this creates a lot of friction. By keeping the drill bit from getting too hot and becoming blunt, water will increase their working life.

What size hole saws do electricians use?

The primary sizes of the hole saw used by electricians vary according to application. However for recessed lighting you want a kit that ranges from 50mm to 90mm and even small for drilling holes in joints for feeds.

What kind of drill do I need for a hole saw?

You need a drill with a bit of torque for cutting holes in wood or anything sturdier. Most named brands do the job, checkout or best drills for electricians post for more info. You want to stay away from cheap brands as they tend to lack power.
