Hole saw and core drill bits are great for creating holes bigger than standard drill bits. Used across many applications and materials, hole saws are able to more rapidly cut large holes as there is less material that needs to be removed.

### What is a Hole Saw?

Hole saws are typically made up of 3 parts, an arbor, a central drill bit and the hole saw cylinder itself. An arbor or mandrill is the main body attachment that is used with a hole saw to secure it to the centre drill bit as well as to the drill itself. The arbor shaft is fixed into the chuck of the drill and the hole saw is attached to the arbor typically by being screwed on.

The centre of the arbor typically has a central hole to receive a drill bit that is fixed into place via a grub screw. This drill bit is used to create a small, central pilot-style hole that allows the user to keep the drill steady when the hole saw cylinder starts to cut. Due to the way a hole saw cuts, without the central drill, it is very difficult to keep the drill steady and work safely.

Alternatively, if the hole saw is being used in a fixed drill such as a pillar drill where both the drill and the workpiece are in fixed positions, the central drill bit may not be necessary.

#### Where can I use a Hole Saw?

Hole saws and core drill bits are the ideal solution in a wide range of applications. Whether in a professional workshop, on a busy job site or just for the average DIY'er, hole saws provide a tool that is invaluable.

Different saws and bits are suitable for different materials so always ensure the hole saw or core drill you have is suitable for the material you are working with but with suitable options for wood, metal, masonry, plastic and so many more, there is always an option available.

Some hole saws and core drill bits even include a built-in central spring to push any material out that has been cut to aid you in both ease of working and huge time-saving. Always ensure your hole saw or core drill is free from any previously cut material to work in the safest way possible.

Arbors, HSS, Bi-Metal Cobalt & Cobalt Steel Arbors | RS

<p>Some of the hole saws that you can purchase from the market come along with arbors attached to them. However, you will also be able to find hole saws where you can discover detachable arbors. If you look around, you will figure out that there are hole saws, which are not sold with any arbors at all as well. To make sure that you make the right choice, you need to have a clear understanding about hole saw arbors.</p><h2>What are hole saw arbors?</h2><p>The primary objective of hole saw arbors is to attach the drill bits to hole saws. In other words, the arbors are in a position to attach to a hole saw, so that you will be able to hold it in a drill. You will be able to use the arbor along with hole saws that come with appropriate thread and size. On the other hand, pilot bits are helpful to you at the time of attaching the arbor inside your hole saw. They will be able to drill a starter hole, which can keep the hole saw away from changing position once you start cutting. The pilot bits will usually be changed when they are damaged or worn out.</p><h3>How do HSS arbors work?</h3><p>Now you have a basic idea on what is a hole saw arbor all about. While keeping that in mind, let's also focus on how HSS arbors work. The pilot bit, a twisting drill in the middle of the arbored hole saw, has a fixed shank. When the saw is in operation, this pilot drill bit was utilized to stabilize it.</p><p>Similar to a typical drill bit, the pilot bit would initially produce a tiny hole when cutting soft materials like wood or plastic tubing, and the teeth of something like the hole saw will come next. It is possible for the remainder of the saw to cut via the material without wandering or drifting since the drill bit already has pierced and embedded itself in the substance.</p><p>Walking occurs when the material and the sawing teeth are not securely fixed in one area, which might cause them to move from the intended location during drilling. This is avoided by the pilot bit, which offers a stable point of contact. With the help of arbor hole saw, you will be able to stay away from such problems from taking place.</p><h3>Getting the most out of Bi-Metal cobalt arbors</h3><p>When you get a bi meal hole saw arbor, you will come across the need to get the most out of it. An arbored hole saw is mostly used to repeatedly cut an exact hole in the material. The fixed arbor is robust and will run with correct circularity since it is a crucial component of the cutting bit. Throughout the drilling operation, the pilot drill makes sure that precise placement and precision are maintained. The outcome is a tidy hole with a variety of applications based on the hole's intended function. The pilot hole will, however, be in the middle of the material that was removed. Based on why the hole was made, this might or may not be wanted.</p><h3>Should you buy Cobalt steel arbors?</h3><p>You need to check and determine what the main requirement of you starting to use a hole saw is. For example, you need to check and see whether you wish to cut a hole within a workpiece using it. Or else, you need to check and see whether you wish to cut a rounded piece cut out of it. If you want to cut out a round piece, you should also check and see whether there is a need to have a small hole in a material in the center. While keeping these facts in mind, you can buy the right hole saw arbor from our store.</p>

Hole Saw, Metal Hole Saw, Diamond Hole Saw Drill Bit | RS

<p>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.</p><p>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.</p><p>At RS, we offer hole saws in single parts and kits suitable for both professionals and DIYers.</p><p>Whereas, when selecting a hole saw, ensure that its length (which varies between sizes and types) is sufficient to penetrate all surfaces.</p><h2>Types of hole saws</h2><p>Different types of hole saws are available, each with a different range of materials they can cut.</p><h3>1. Metal hole saws</h3><p>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.</p><p><strong>Fits most too:</strong></p><p>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.</p><h3>2. Diamond hole saw</h3><p>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.</p><p><strong>Fits most too:</strong></p><p>Typically, ceramic tiles are drilled with hole saws with diamond edges.</p><h3>3. Concrete hole saw</h3><p>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.</p><p>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.</p><p>Fits most too:</p><p>Core drill bits with tungsten carbide tips are used for rotary drilling through masonries, such as brickwork, stonework and concrete.</p><h3>4. Tile hole saw</h3><p>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.</p><p>These hole cutters should be used on masonry drill bits and not on hammer drills.</p><p><strong>Fits most too: </strong></p><p>Ceramic tiles, cement sheets, wood, and fibreglass are all common materials for TCT hole cutters.</p><p><strong>5. Masonry hole saw</strong></p><p>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.</p>
