Bi-Metal Hole Saw Kit, 31-Piece All-Purpose Combo

The 31-Piece Bi-Metal Hole Saw Kit from our company is a superior value product that contains the most commonly used 22 hole saws, ranging from 3/4" to 4-3/4". In addition to the hole saws, the kit includes a comprehensive set of accessories, such as 2 arbors with pilot drills, 3 additional pilot drills, 1 ejector spring, 1 arbor adapter, 1 Allen key, and a 10" extension. This versatile kit is an all-purpose combination of plumbers', electricians', and industrial kits, making it a valuable asset for a wide range of applications.

The kit's compatibility extends to a diverse range of materials, including aluminum, non-ferrous metals, stainless steel sheets, steel pipes and profiles, softwood, hardwood, plywood, drywall, OSB, MDF, fiberglass, gypsum board, Formica, plaster, and chipboard. This makes it ideal for tasks such as kitchen and bedroom installation, car and house repair, plumbing, construction, maintenance, and automotive applications, as well as for DIY enthusiasts.

The hole saws feature a variable 4/6 TPI (teeth per inch) configuration, which allows for a faster and smoother cut, reduced torque build-up, and enhanced chip removal. The progressive teeth strip provides a powerful bite on contact with irregular surfaces, enabling rapid drilling and more aggressive cutting. The shaped gullets between the two sharp teeth further accelerate chip clearance during drilling.

The toughened, heavy-duty backing plate is constructed with thick steel, providing outstanding concentricity that can reduce runout and vibration, ensuring a smooth and precise cut. The special spring steel body adds strength and rigidity, minimizing vibrations for super clean cuts.

The 2-inch hole saw depth provides increased cutting depth, while the new-designed side slot enhances leverage for faster and easier slug removal. The ejector spring fits over the pilot drill and pushes the core out of the hole saw after the cut is complete. The arbor adapter further expands the kit's versatility by allowing a small arbor thread (1/2"-20 UNF) to accommodate a large hole saw thread (5/8"-18 UNF).

To top it off, we offer a 100% satisfaction guarantee, ensuring your confidence in the purchase. We are confident that you will be super impressed with this versatile and reasonably priced Bi-metal Hole Saw Kit, which is a must-have for a wide range of DIY, construction, and professional applications.
