Engineered for Extreme Durability in Sheet Metal Applications

The Bosch HTWS Edge™ Impact Tough™ Hole Saw Set is built to withstand the rigorous demands of professional electrical, HVAC, and plumbing work. Delivering up to 2X the life of standard impact-rated hole saws, this set offers unbeatable dependability and value. Each saw features precision-engineered 8-TPI bi-metal teeth designed specifically for clean, rapid cuts through sheet metal. Optimized for today’s high-torque impact drivers, these tools allow you to harness maximum power without compromising on cut quality or tool longevity.

Convenience and precision are at the core of the Edge™ design. These hole saws feature an integrated one-piece construction, eliminating the need for separate arbors or pilot bits. The 1/4-inch hex shank ensures universal compatibility with impactors and standard drills, providing a secure, slip-free grip. Additionally, each saw is equipped with a shoulder depth stop to prevent breakthrough and damage to components behind the work surface, while the integrated pilot bit spring automatically ejects material plugs, keeping your workflow smooth and efficient.

Key Features

  • Extended Lifespan: Durable design delivers 2X life compared to standard impact-rated hole saws.
  • Optimized for Sheet Metal: Bi-Metal 8-TPI teeth geometry ensures clean, burr-free cutting.
  • Impact Ready: Engineered to handle the high torque and speed of modern impact drivers.
  • Safety Depth Stop: Integrated shoulder prevents over-drilling and protects materials behind the cut.
  • Automatic Ejection: Pilot bit spring forces the material plug out immediately after the cut.
  • One-Piece Convenience: Fully integrated design means no separate arbor or pilot bit is required.
  • Universal Fit: 1/4 In. hex shank works seamlessly with high-torque impactors and drill drivers.
