Our bi-metal holesaws and compatible arbors are engineered for everyday contractors, electricians, and plumbers who cut through wood, thin-gauge steel, plastics, and composite panels without swapping blades. Manufactured from high-speed steel teeth welded to a flexible alloy body, bi-metal holesaws combine long life with shock resistance so teeth stay sharp under intermittent heavy loads. Available in a wide range of diameters and tooth counts, these sets include threaded arbors with pilot drills for accurate centring and quick blade changes. Choose from standard or quick-change arbors; many options accept arbor adaptors for drill presses and portable drivers. Ideal for door hardware, cable runs, conduit penetrations, and HVAC duct work, these holesaws deliver fast, clean cuts and good longevity for mixed-material job sites.
