The Drilax 2-3/8 inch Diamond Hole Saw is a heavy-duty tool designed for both wet and dry use, ideal for drilling through concrete, brick, masonry, and other hard materials. With a 3/8-inch standard shank, this hole saw is compatible with most cordless or electric drills.

  • Gold Series Sintered Teeth: High-grade industrial diamonds are sintered directly into the laser-welded teeth, providing aggressive cutting power and an extended service life without the need for water.

  • Direct Drilling Design: The stable steel body is balanced for direct drilling, ensuring no chipping or uneven edges for a professional finish on every installation.

  • Extra-Deep 2-Inch Cut: Specifically engineered for thick masonry walls, allowing you to pass through exterior foundations and blocks in a single pass.

  • HVAC Professional’s Choice: Rugged build quality designed to handle the high-torque demands of installing large-diameter ventilation and ductwork.

  • No Adapter Needed: The integrated 3/8 inch round shank ensures universal compatibility with the drills you already own, saving you the cost of specialized equipment.

  • Durable Alloy Construction: The heavy-duty steel body aids in heat dissipation, ensuring the bit remains stable and true during extended drilling sessions.

Compatible Materials

  • Materials: Brick walls, concrete blocks, stucco, foundation slabs, natural stone, cinder block, and pavers.
  • Tool Compatibility: Works with all standard 3/8" or 1/2" corded and cordless drills (DeWalt, Milwaukee, Ryobi, Makita).
  • Pro Series Tip: For sizes in this series that do not include a guide, we recommend creating a simple template out of scrap wood to ensure a perfect start.
  • Warning: Not recommended for glass, mirrored surfaces, or delicate decorative tiles.

How To Use

  • Drill Mounting: This bit features a universal 3/8 inch shank that fits directly into any standard corded or cordless power drill. No specialized adapters are required.
  • Starting the Cut: Since this model does not include a mechanical guide, we recommend creating a simple guide template out of scrap wood or plastic. Alternatively, start the cut at a 45-degree angle to notch the surface, then slowly bring the tool upright to 90 degrees.
  • Operating Technique: Use a steady, moderate speed. Apply light, controlled pressure and let the sintered diamond teeth do the cutting. Do not use the hammer setting on your drill.
  • Heat Management: Although engineered for dry use, using a wet sponge or a small stream of water will keep the bit cool and significantly reduce dust.
  • Safety Note: Avoid contact with rebar. If rebar is encountered, stop drilling immediately to prevent damage to the sintered teeth.

Use Cases

  • HVAC & Plumbing: Perfectly sized for installing 2-inch PVC pipe sleeves, conduit, and drain lines through foundation walls.
  • Electrical Installations: Create clean openings for heavy-duty electrical service entries and junction box paths in masonry.
  • Aquarium & Specialty: Ideal for drilling bulkheads in large glass fish tanks (wet use required) or specialized stone planters.
  • Structural Projects: Drilling anchor points for posts and supports in concrete slabs or brick walls.
