Bi-metal Hole Saws

Bi-metal hole saws combine two distinct materials—high-speed steel (HSS) teeth fused to a flexible spring steel body—to deliver versatility across multiple applications. The HSS teeth provide cutting efficiency for metals, plastics, and wood, while the resilient body absorbs vibrations, enhancing stability during operation. This dual-material construction allows the tool to withstand high torque and accidental lateral forces, making it ideal for irregular surfaces or angled drilling. 

Bi-metal variants are particularly valued in HVAC and electrical work, where technicians frequently encounter mixed materials like sheet metal, conduit, and wooden framing. Their tooth geometry varies between fine and coarse configurations, enabling adaptation to material thickness and hardness. Additionally, the bi-metal design offers cost-effectiveness by balancing performance and longevity, as only the HSS segments wear down over time. These hole saws often feature quick-change compatibility, streamlining workflow in time-sensitive projects.
