A raised shoulder around the base of the hole cutter, designed to prevent over-drilling or breakthrough when it is not desired Well-crafted hole cutter bits possess relatively thin cylindrical walls in proportion to their internal diameter. This deliberate design reduces friction between the teeth and the work surface, resulting in reduced user effort when penetrating the material. Consequently, less strain is placed on the drill's motor during the drilling process. When it comes to different applications and working environments, there is a wide range of hole cutters and hole saw accessories available. Some common applications include:

Diamond tipped hole saws, also known as diamond core drill bits, are cutting tools specifically designed for harder materials such as stone, tile, glass, and ceramics. Unlike traditional hole saws with metal teeth, diamond hole saws feature a circular body embedded with diamond grit on the cutting edge. This section will explain how diamond hole saws work, their benefits, and why JCB Tools' DiamontTech offers professional-grade diamond hole saws for your drilling needs.There are different types of hole saws and they generally range in size between 14mm and 210mm in diameter. Holes below this size can usually be achieved using a standard drill bit, while larger holes will generally require alternative cutting methods. These bits are hollow, round bits with a jagged fracture-resistant bi-metal cutting edge made from HSS (High-Speed Steel). They are used to make clean, precise holes in a variety of materials, including aluminium, steel and non-ferrous metals. If you are planning a project that requires smooth holes that can go right through the material you are drilling, you would use this type of bit. How do they work? Ensure you use a drill with sufficient power for hole cutting. While cordless models may suffice for thinner or softer materials, a minimum of a 14V model is required, such the JCB 18v Combi Drill.. Avoid attempting to bore holes through masonry or heavier timber (over approximately 50mm) using a battery-operated drill, instead opt for a more powerful corded drill such has the JCB Corded Hammer Drill A hole saw, also known as a hole cutter, is a specialised drill bit designed to create larger circular holes than standard drill bits. These versatile drilling tools are widely used in various industries and applications. Different types of hole saw bits are available for materials like timber, plastics, metal, ceramics, masonry, glass, and more. What are Diamond Hole Saws? Can hole saws drill through metal? If you need to make clean, round holes in metal, you may be wondering whether these bits are a good option. Hole bits are frequently used to drill holes in wood. However, they can also be used on other materials such as plastic, non-ferrous metals, aluminium, and steel. While other metal drill bits are good for drilling a variety of metal types, hole bits are the best choice to create accurate holes with no rough edges. Knowing how to use these bits and which type of hole saws for your metal project will help you get the best results.

Before we give you the ins and outs of using your hole saw for drilling metal, it helps to understand what this drill bit is used for and how it works. Here’s what you need to know. What are hole bits?In situations where you need to enlarge an existing smaller hole, such as when installing a new halogen downlight with a wider diameter than the previous one, it can be challenging to find a surface to cleanly start the cut. If accessible, clamping a scrap piece of timber behind the workpiece can provide a drilling surface for the pilot hole. Alternatively, a hole saw re-work adapter can be a useful accessory. It allows you to attach two different diameter hole saw bits simultaneously, with the smaller one acting as the guide or arbor bit (matching the existing hole width) and the larger attachment cutting a new, larger hole around it. Masonry hole saws, also known as "core drill bits," usually have widely spaced teeth, and some may even feature diamond-tipped teeth, such as the JCB DiamondTech for added hardness and cutting power. The wider spacing helps prevent clogging and binding, ensuring efficient material removal. "Variable pitch" hole saws with irregular tooth spacing can further reduce vibration, noise, and wear, though they may produce slightly rougher holes. Regardless of the material or surface you're working on, never force the drill bit to go faster than its natural pace. Apply gentle and consistent pressure to achieve a clean and perfectly round hole. Start slowly and gradually increase the rotation speed as you progress.
