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" shank that fits directly into any standard corded or cordless power drill. No specialized adapters or high-end core machines are required.
  • Using the Locator Guide: Secure the included removable locator guide to the surface to ensure exact tool positioning. This prevents the bit from wandering during the start. The guide can also optionally hold water for secondary cooling.
  • Starting the Cut: If not using the guide, start at a slight 45-degree angle to notch the surface, then slowly bring the tool upright to 90 degrees.
  • Operating Technique: Maintain a steady speed. Apply light, controlled pressure and let the sintered diamond teeth do the work. Do not force the tool.
  • Cooling: Although engineered for optimal dry use, using water is optional to further reduce heat and suppress dust during deep masonry cuts.
  • Safety Note: Avoid contact with rebar. If rebar is encountered, stop drilling immediately to prevent damage to the sintered teeth.

Use Cases

  • HVAC & Ventilation: Perfectly sized for installing vents, smaller ductwork, exhaust fans, and air conditioning lines through masonry walls.
  • Plumbing & Electrical: Drilling clean passages for drainage lines, 2-inch pipe sleeves, and electrical conduit in basement foundations.
  • Construction & Renovation: Creating precise openings in cinder blocks, poured concrete walls, and pavement stones.
  • Landscaping Projects: Core drilling into natural rocks, boulders, and decorative stone for outdoor utility or lighting installations.
