The adjustable hole saw cutter set represents a major advancement in both masonry and carpentry equipment, offering a flexible alternative to the use of traditional fixed-diameter hole saws. In order to handle the extreme conditions found at all types of construction sites, the adjustable hole saw has been designed to provide precise cuts in a wide variety of materials which includes; Aluminum, Plaster Board, Composite Building Panels etc. A primary benefit of using an adjustable system is that one piece will be able to replace a whole set of individual hole saws. Not only does this reduce the weight contractors have to carry in their tool bags but it also simplifies the process by giving the user the capability to enter exactly what measurement he and she needs for recessed lighting and  ventilation ducting or piping without having to swap hardware between different jobs.

The most common form of constructing these cutters involves a heavy-duty pilot drill bit being placed centrally between two or more adjustable blades which are connected to a sliding scale. Often times these adjustable blades are tipped with either Tungsten Carbide (TC) or High-Speed Steel (HSS), providing them with the ability to penetrate non-ferrous metals like aluminum while providing a smooth edge on softer materials like plaster board. Using the adjustable cutter when making holes in plaster board/drywall significantly reduces the amount of jagged edges and the amount of dust created by traditional hole saws. This creates a true circle for electrical boxes/fixtures that produces a very professional finish. Additionally, the ability to adjust the radius is extremely beneficial in older buildings/custom homes/buildings where typical hole sizes may not fit the new architectural elements/requirements.

A key element of this design is durability. Construction environments frequently subject equipment to substantial amounts of torque and abrasive materials. The center mandrel was built to withstand large amounts of rotational force so that the blades remain stable and do not “walk” or oscillate during the cutting process. Stability is extremely important when cutting aluminum sheets/thin walled extrusions as small deviations in precision can cause the material to tear/deform. Most kits come with a protective dust cover/shield/cowl that encloses the cutting mechanism. Two benefits exist from this clear enclosure: it protects the operator from flying debris and captures the fine white dust produced when cutting gypsum based plaster board. This helps keep the working area cleaner and safer for the tradesman’s lungs.

The improved productivity resulting from utilizing an adjustable hole saw cannot be exaggerated for today’s builder. Rather than interrupting his/her project to find a specific size, the user merely loosens a locking screw, moves the cutting arm(s) to the diameter needed as shown on the included metric or imperial scale and then retighten. The ability to the customize each penetration through a ceiling and wall to the exact requirements of each particular task ensures accuracy and they quality control. It eliminates the “good enough” attitude that results in gaps/caulking/patching. Whether your project requires you to install several LED down lights in a residential living room or route aluminum conduit in a commercial warehouse, the adjustable cutter offers a consistency/speed of production that far exceeds that of other traditional products.

Overall, an adjustable hole saw cutter kit is an incredibly powerful multi-functional product that meets many of the challenges presented by modern building materials. With its ability to bridge the gap between delicate interior finishes and harsh site preparations, it is an excellent solution for builders to make precise cuts in aluminum and plaster board with relative ease. Built with durable construction materials, it should provide years of service; combined with its versatility, it is a cost-effective solution for those professionals that value precision and efficiency. Adding an item such as this into a normal kit will ensure that regardless of what diameter is needed, the builder/operator will have a reliable means of executing a clean, accurate, and professional grade cut on the first try.
