A bi-metal hole saw is a versatile cutting tool designed for drilling holes in various materials. Here are some key points about bi-metal hole saws:

1. Construction and Features:

   • Bi-metal hole saws consist of two materials: a high-speed steel (HSS) cutting edge and a durable steel body.
   • The HSS teeth provide excellent cutting performance, while the steel body ensures durability.
   • They often feature a Vario-Pitch tooth system, which allows for quick drilling progress and prevents jamming.
   • Precision manufacturing results in neat, circular holes.

2. Applications:

   • Bi-metal hole saws are suitable for cutting through a range of materials, including:
     • Wood
     • Metal (such as aluminum and mild steel)
     • Plastic
     • Laminates
     • Brass

3. Plug Ejection:

   • Bi-metal hole saws typically have a large, continuous slot that provides leverage for easy plug ejection and removal.
