Hot Tapper, Bi-Metal Hole Saws

Bi-metal hole saws are critical cutting instruments used for precise drilling through tough materials such as stainless steel, mild steel, aluminum, and brass. A bi metal hole saw for steel, which is widely used in hot tapping equipment and industrial applications, combines adaptability and strength to efficiently cut metal pipe and sheet.

These metal cutting hole saws or Bi-metal hole saw bits are made with M42 high-speed steel with 8% cobalt, provide remarkable edge retention and endurance, lasting more than twice as long compared to standard models. The variable tooth pitch design reduces vibration and produces smoother, faster cuts over a variety of metal surfaces. Whether you're making parts or doing maintenance, these hole saws provide a reliable choice for clean, consistent output.

Key Features & Benefits of Our Bi-Metal Hole Saws

Professionals rely on our bi-metal hole saws for plumbing, electrical, HVAC, and industrial fabrication applications because they are built to last. Each bi-metal hole saw is designed to produce clean, accurate holes in even the toughest metals.

• Cuts a Wide Range of Metals: Suitable for stainless steel, mild steel, brass, aluminum, and copper, making it a versatile instrument for both shop and field use.
• Variable Tooth Pitch Design: Reduces vibration and heat buildup, resulting in smoother, cleaner cuts even in multilayer or thin-walled metals.
• Side Ejection Slot: The built-in side slot provides more leverage and streamlines slug removal, allowing you to work faster and save downtime between cuts.
• Deep Cut Models Available: Some models have a greater cutting capacity for thick-wall pipe, conduit, and structural steel applications.
• Premium M42 High-Speed Steel with 8% Cobalt: Offers excellent wear resistance and heat tolerance. The end result is a cutting edge that lasts more than twice as long as traditional bi-metal designs.
• Precision Cap Design: Reduces runout and increases tracking, ensuring holes are drilled precisely where required - essential for hot tapping tools and precise installations.

How to Choose the Right Bi-Metal Hole Saw Bit?

When choosing a bi-metal hole saw, it is critical to evaluate the requirements of your particular application. The correct tool will result in cleaner cuts, a longer tool life, and increased efficiency, particularly when working with metals such as steel, aluminum, or brass.

Whether you're using a single saw or a bi-metal hole saw kit, selecting the right size and features can increase both safety and performance.

Key factors to consider:

• Material Type: Select a saw that is rated for the metal or composite being cut (e.g., steel, stainless, aluminum).
• Hole Diameter: Make sure the saw size matches the opening for the fitting, conduit, or pipe.
• Cutting Depth: Make sure the hole saw can cut through the thickness of the workpiece.
• Tooth Design: Look for variable tooth pitch to reduce vibration and make smoother cuts.
• Durability: Choose saws constructed of M42 high-speed steel with cobalt for longer life and superior performance in tough materials.

FAQs

What is a Bi Metal Hole Saw?

A bi-metal hole saw is a cutting instrument made by joining two types of metal, usually high-speed steel teeth and a flexible alloy steel body. This combination offers durability, heat resistance, and the ability to cut through strong materials such as steel, aluminum, brass, and stainless steel with little wear.

What materials are bi-metal hole saws compatible with?

Bi-metal hole saws are built for versatility and can cut through a wide range of materials in construction, plumbing, and general fabrication. Bi-metal hole saws are suitable for cutting: Stainless steel, Mild steel, Aluminum, Brass, PVC and other plastics, Wood.

What is better Bi-Metal or Carbide Hole Saws?

It depends on the application. Bi-metal hole saws are versatile, inexpensive, and suitable for cutting a variety of metals and soft materials. Carbide hole saws are better suited for extremely hard or abrasive materials such as tile, cast iron, or fiber cement, but they are often more expensive and less flexible across material types.

How to Attach a Bi-Metal Hole Saw to a Drill?

To attach a bi-metal hole saw to a drill, first screw it into a compatible mandrel with a pilot drill bit.  Make sure the mandrel's pins or drive posts line up with the holes in the saw's base, then tighten everything down securely.  Insert the mandrel shaft into your drill chuck and tighten it tightly.   Once everything has been secured, the setup is ready for use.
