Description

EXPERIENCE ENHANCED DURABILITY WITH COBALT ALLOY PERFORMANCE

Drill with confidence using the Bosch 1-11/16 Inch Bi-Metal Hole Saw, engineered to meet the demands of professional electricians, plumbers, and contractors. This high-performance accessory is constructed from a premium bi-metal blend featuring 8% cobalt alloy (M42). This superior material composition provides higher heat resistance and significantly extends the life of the cutting edge, making it the ideal choice for heavy-duty applications in both wood and metal. Whether you are boring through dimensional lumber, plywood, sheet metal, or stainless steel, this hole saw delivers consistent, reliable results.

Speed and efficiency are at the heart of the design. The hole saw features Bosch's innovative "Progressor" tooth geometry with a 5 TPI (Teeth Per Inch) configuration. This variable tooth pitch ensures faster cutting speeds and cleaner holes by effectively clearing chips and reducing vibration. To withstand the torque of demanding drills, the cup is built with a reinforced shoulder that adds strength and prevents structural failure. Compatible with both standard and Quick Change™ mandrels (adapters required for Quick Change), this versatile tool is a must-have addition to any drilling kit.

Key Features

  • 8% Cobalt Alloy: Premium M42 bi-metal construction offers superior heat resistance and extended blade life.
  • Progressor Tooth Design: Optimized 5 TPI variable pitch cuts faster and lasts longer in multiple materials.
  • Reinforced Shoulder: Structural strengthening at the base prevents ovaling and breakage under high torque.
  • Multi-Material Versatility: Designed to cut cleanly through wood, metal, plastics, and composite materials.
  • Universal Compatibility: Works with standard threaded arbors and is compatible with Quick Change systems (with adapters).
  • Deep Cutting Capacity: Features a generous cutting depth to handle thick materials in a single pass.

Pro-Tip: Heat is the number one enemy of hole saws, especially when drilling metal. To extend the life of your cobalt hole saw, operate your drill at a slower RPM and apply cutting fluid to the cut. This simple step lubricates the teeth and dissipates heat, preventing the bit from dulling prematurely.
