Hole Saws
When compared to a standard drill bit, a hole saw is able to cut larger holes. Instead of cutting the workpiece, they create a hole. Even your power drill is equipped with an arbour for mounting the hole saw.
Any handyman's toolkit should include a hole saw for cutting holes in a variety of materials. With a premium hole saw at hand, it will be easy for you to complete your project efficiently.
At RS, we offer hole saws in single parts and kits suitable for both professionals and DIYers.
Whereas, when selecting a hole saw, ensure that its length (which varies between sizes and types) is sufficient to penetrate all surfaces.
Types of hole saws
Different types of hole saws are available, each with a different range of materials they can cut.
1. Metal hole saws
The bodies of metal hole saws are made of high-carbon steel, along with high-speed steel teeth, making them durable and flexible. As a result of their shatter-proof construction, they are suitable for a wide range of materials. The maximum depth of cut is usually about 30mm.
Fits most too:
Materials such as hardwood, chipboard, plywood, PVC, wallboard, and plastic can be cut with them. A variable metal hole saw deep cut is best suited to wood, metal, and hard surfaces.
2. Diamond hole saw
In some hole saws, there are no teeth, but rather diamond coatings or diamond-infused steel that increases their durability and hardness. Due to their durability and heat resistance, diamond hole saws provide excellent durability. It is recommended to quench these saws periodically in water to cool down the blade despite their high heat resistance. The shank of this hole saw is round. Drill chucks of any size can accommodate round shanks.

Typically, ceramic tiles are drilled with hole saws with diamond edges.
3. Concrete hole saw
Does your home have a concrete tabletop or foundation in your bathroom or living room? The best concrete hole saws are made of tungsten carbide.
High-speed rotation ensures easy penetration with tungsten carbide tips, which are extremely hard. In order to avoid damage to the tips, these hole saws are not suitable for use with hammers or impact tools. A separate arbour can be purchased.
Fits most too:
Core drill bits with tungsten carbide tips are used for rotary drilling through masonries, such as brickwork, stonework and concrete.
4. Tile hole saw
They are designed to cut through very dense materials using tungsten carbide-tipped drill bits. In addition to being known as tile hole saws, also known as TCT hole saws and single tooth hole cutters, they are also multi-toothed and can be used with a variety of different materials.
These hole cutters should be used on masonry drill bits and not on hammer drills.
Fits most too:
Ceramic tiles, cement sheets, wood, and fibreglass are all common materials for TCT hole cutters.
5. Masonry hole saw
During hole cutting with masonry hole saws (stone, concrete, brickwork), water is used to quench some core drill bits. As a result, cutting into dense materials creates a lot of friction. Keeping the drill bit from becoming too hot and blunt will increase its working life.
