Description

SUPERIOR CUTTING LIFE WITH 8% COBALT ALLOY

Power through your drilling tasks with the Bosch 1-9/16 Inch Bi-Metal Hole Saw. Designed for professional durability, this hole saw features a premium bi-metal construction infused with 8% cobalt alloy (M42). This advanced metallurgy provides superior heat resistance and extends the cutting life of the teeth, making it an excellent choice for demanding applications in both wood and metal. Whether you are boring through dimensional lumber, plywood, aluminum, or mild steel, this tool delivers consistent, reliable performance hole after hole.

Efficiency is built into the design with Bosch's innovative "Progressor" tooth geometry. The variable 5 TPI (Teeth Per Inch) configuration cuts faster and cleaner by effectively clearing chips and reducing vibration during operation. To withstand the high torque of modern drills, the cup features a reinforced shoulder that adds critical strength, preventing ovaling and breakage. Compatible with standard threaded arbors and adaptable for Quick Change™ systems (adapter sold separately), this versatile hole saw is a staple for any serious toolkit.

Key Features

  • Enhanced Durability: 8% Cobalt alloy construction resists high heat for longer life in tough materials.
  • Fast Cutting Action: Progressor tooth design with 5 TPI variable pitch ensures rapid, clean cuts.
  • Reinforced Strength: Shoulder design adds structural integrity to withstand high-torque applications.
  • Versatile Application: Optimized for cutting wood, metal, plastic, and composite materials.
  • Deep Cut Capacity: 1-5/8 inch cutting depth easily handles 2x lumber and thick materials.
  • Universal Fit: Works with standard mandrels and is compatible with Quick Change systems (adapter required).

Pro-Tip: To prevent the hole saw from "walking" or skating across your material when starting a cut, always use a mandrel with a sharp pilot bit. Start the drill at a low speed until the saw teeth cut a groove into the surface, then gradually increase speed while applying steady, even pressure.
