The Drilax 2-3/4 Inch Diamond Hole Saw is a commercial-grade core bit designed to bridge the gap between heavy industrial equipment and standard home tools. By utilizing high-performance diamond grit sintered directly into the cutting edge, this bit maintains its sharpness and structural integrity even when tackling abrasive materials like aged concrete or kiln-fired brick. It allows users to achieve professional-grade results using the cordless or electric drills they already own.

Benefits

Cost Efficiency: Save over 80% on project costs by performing your own core drilling instead of hiring specialized contractors.

Universal Compatibility: The 3/8 inch shank ensures you don't need to purchase expensive SDS or high-torque specialized machines.

Exceptional Durability: Sintered diamond technology means the cutting edge is integrated into the material, not just plated on the surface, preventing premature wear.

Versatile Operation: Optimized for dry job sites where water mess must be minimized, yet fully capable of wet drilling for maximum tool longevity.

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 & Ventilation: Ideal for creating precise entry points for 2-1/2 inch exhaust pipes and ventilation ducting.
  • Plumbing & Drainage: Sized perfectly for passing heavy-duty PVC drain lines and stack pipes through foundation slabs and walls.
  • Electrical Service: Create clean, oversized openings for electrical conduit bundles and service entrance cables in masonry.
  • Specialty Masonry: Core drilling for fence posts, gate anchors, or structural supports in brick, stone, or cinder block.

Technical Specifications

  • Hole Diameter: 2-3/4 inches
  • Cutting Depth: 2 inches
  • Shank Type: 3/8 inch Universal Round Shank
  • Construction: Solid Steel Body with Laser-Welded Sintered Diamond Teeth
  • Locator Guide: Not Included (Use scrap-wood template)

A: It is designed for heavy-duty masonry, including concrete blocks, brick, stone foundations, pavers, marble, and granite. It can also be used on glass and fish tanks when used with water.
Q: Does it require a pilot hole?
A: No. Center pilot bits are primarily for wood or metal. These diamond masonry bits are designed for direct drilling. Use a template or the angled-start method to keep the bit on target.
Q: Can I use this with my cordless drill?
A: Yes. The 3/8 inch shank is the standard size for most cordless and electric hand drills.
