Holesaws Bi Metal & Arbors

1 product

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.

Frequently Asked Questions

The arbor serves as the essential connecting link between the holesaw blade and the power tool, such as a drill or lathe. It provides the stability and torque transfer necessary to spin the saw blade smoothly, ensuring that the circular cuts remain accurate and consistent across different materials.

This range features high-quality professional options, including the Electricians Holesaw Kit which contains a variety of common diameters for electrical installations. Customers can also find individual components such as the 76mm and 83mm TCT (Tungsten Carbide Tipped) holesaws designed for heavy-duty applications and specialized arbors with pilot drills.

These tools are engineered for versatility and can handle a wide array of industrial and construction materials. They are particularly effective for cutting through sheet metal, stainless steel, cast iron, fiberglass, plastic, and various types of timber, making them ideal for HVAC, electrical, and general fabrication tasks.

TCT holesaws are designed for maximum wear resistance and longevity. The carbide tips allow the saw to maintain its sharpness significantly longer than standard steel blades, resulting in cleaner, burr-free holes even when working with tough or abrasive substrates like composites and thicker metals.

Many of the holesaws in this collection feature variable pitch teeth, which help to reduce vibration and facilitate a faster, smoother cutting action. Additionally, they often include multiple knock-out slots on the side of the barrel, making it much easier for the user to remove the core or "slug" of material once the cut is completed.

While holesaws are physical cutting tools, HK Calibrations offers the unique ability to schedule calibration for professional kits and associated measurement instruments. This ensures that the tools meet specific precision standards required for high-stakes industrial environments where dimensional accuracy is paramount.
