Drilax 2-1/2 Inch Diamond Hole Saw is designed for clean, controlled drilling in hard construction materials using an angle grinder or a standard drill (adapter included). Built with a vacuum-brazed diamond cutting edge and a rigid steel core, it delivers dependable performance for professional trades and experienced DIY users.

Key Features

    • Dual Tool Compatibility
      Standard 5/8"-11 threaded body fits most angle grinders; includes an adapter for use with electric drills.
    • Dry Drilling Optimized
      Engineered for dry cutting with side slots that aid heat dissipation and debris removal.
    • 1-3/8" Cutting Depth
      Suitable for drilling through thick tile, stone, and countertop materials in a single pass.
    • Vacuum-Brazed Diamond Edge
      Industrial-grade diamonds are permanently bonded for consistent cutting performance and extended service life.
    • Versatile Applications
      Ideal for plumbing penetrations, pipe sleeves, HVAC openings, electrical pass-throughs, and speaker installations.

Compatible Materials

  • Materials: Porcelain tile, ceramic, granite, quartz, marble, slate, brick, and non-reinforced masonry.
  • Tool Compatibility: Fits most Angle Grinders (Makita, Bosch, DeWalt) and all standard Power Drills (Ryobi, Milwaukee, Ridgid) using the included adapter.
  • Application Note: Perfect for plumbing penetrations, pipe sleeves, and HVAC ducting.

How To Use

  • Angle Grinder Setup: Thread the hole saw directly onto the 5/8"-11 spindle. Start at a 45-degree angle to create a "crescent" guide, then slowly tilt the tool upright.
  • Standard Drill Setup: Use the included adapter. Tighten the chuck securely and operate at high RPM.
  • Pro Tip: Use a steady, light circular motion ("oscillating") while drilling to help clear dust and keep the cutting edge cool.
  • Heat Management: For deep cuts, pause for 10 seconds every 30 seconds of drilling to allow the air-cooled side slots to dissipate heat.

Use Cases

  • Kitchen & Bath Renovation: Installing 2.5" shower valves or faucet sets through thick porcelain wall tiles.
  • Countertop Installation: Creating clean pass-throughs for plumbing or electrical lines in quartz and granite slabs.
  • Commercial Masonry: Drilling entry points for electrical conduit or speaker mounting in decorative stone facades.

  • Hole Diameter: 2-1/2 inches
  • Cutting Depth: 1-3/8 inches
  • Connection Type: 5/8"-11 Threaded (Angle Grinder)
  • Adapter: Included (Hex to 5/8"-11)
  • Diamond Type: Vacuum-Brazed Industrial Grade
  • Cooling: Integrated Side Slots (Air Cooled)

F.A.Q.

Q: Can I use this hole saw on glass or mirrors?
A: No. Due to the high-torque vacuum-brazed design, this tool is too aggressive for glass. For glass or mirrors, please use our Drilax Chrome Series wet-drilling bits.

Q: Does it really work without water?
A: Yes. The Pro Series is optimized for dry drilling. However, using a light mist of water or a wet sponge can help with dust suppression in indoor environments.

Q: Will this fit my 3/8" or 1/2" drill?
A: Yes. The included adapter features a standard shank that fits all common 3/8" and 1/2" drill chucks from brands like DeWalt, Milwaukee, and Ryobi.
