Description

SUPERIOR DURABILITY WITH M42 COBALT TECHNOLOGY AND FAST PLUG REMOVAL

Tackle tough drilling applications with confidence using the Bosch HBT175 1-3/4 Inch Bi-Metal Hole Saw. Engineered for professional longevity, this hole saw is crafted from an enhanced M42 alloy containing 8% cobalt. This robust composition allows the saw to withstand high-temperature applications better than standard carbon steel, delivering up to 20% longer life. Whether you are boring through heavy-duty metal, wood, plastic, or drywall, the reinforced shoulder design adds critical strength to prevent ovaling and failure during high-torque use.

Productivity is built into every detail of the HBT175. It features Bosch's exclusive "Triangle Slot" design, a shark-tooth shape on the side of the cup that significantly improves plug ejection efficiency and helps dissipate heat during deep cuts. Combined with the innovative Progressor tooth geometry—which utilizes alternating tooth sizes—this accessory cuts faster and cleaner across multiple materials. With a deeper 1-3/4 inch cup, you can drill through thicker materials like 2x lumber in a single pass, making it an essential tool for electricians, plumbers, and remodelers.

Key Features

  • Enhanced M42 Alloy: Infused with 8% cobalt to resist extreme heat and extend service life by 20%.
  • Triangle Slot Design: Unique side slots allow for rapid plug removal and efficient cooling.
  • Progressor Tooth Design: Alternating tooth sizes enable faster cutting and longer life in wood, metal, and plastic.
  • Deep Cut Capacity: A 1-3/4 inch cup depth easily handles thicker materials and multi-layer substrates.
  • Reinforced Shoulders: Provides added structural integrity for heavy-duty drilling applications.
  • Versatile Compatibility: Works with standard arbors and pairs perfectly with Bosch Quick Change™ universal arbors (sold separately).

Pro-Tip: To maximize the life of your cobalt hole saw when cutting metal, reduce your drill speed (RPM) as the diameter of the hole increases. For a 1-3/4 inch hole in mild steel, keep your speed moderate and apply cutting fluid to keep the teeth cool and sharp.
