Description

HEAVY-DUTY CUTTING PERFORMANCE FOR LARGE DIAMETER HOLES

Tackle large-scale drilling applications with precision using the Bosch HB500 5-Inch Bi-Metal Hole Saw. Engineered for professional durability, this hole saw is constructed from a premium M42 alloy containing 8% cobalt. This high-grade composition provides exceptional heat resistance, allowing the tool to withstand the high temperatures generated when cutting through tough materials like metal and stainless steel. Whether you are running HVAC ducting or installing large plumbing fixtures, this saw delivers the longevity and reliability required for demanding job sites.

The HB500 features Bosch's signature "Progressor" tooth design with a 5 TPI (Teeth Per Inch) configuration. This geometry is optimized to cut faster and stay sharper longer than standard hole saws, ensuring clean entry and exit holes in wood, metal, and plastic. Designed with a reinforced shoulder for added structural strength, it resists stress and prevents failure under high torque. Compatible with standard mandrels and the Bosch Quick Change™ system (with adapters), this accessory is a versatile addition to any pro's toolkit.

Key Features

  • M42 Cobalt Alloy: Contains 8% cobalt for superior heat resistance and extended tool life in metal applications.
  • Progressor Tooth Design: Optimized 5 TPI geometry cuts faster and cleaner through varied materials.

Pro-Tip: When using large diameter hole saws like this 5-inch model, the torque generated by the drill can be significant. Always use a drill with an auxiliary side handle and operate at a lower RPM to maintain control and prevent the saw from binding or "kicking back."
