4-1/2 inch Dry Core Diamond Hole Saw for Brick & Concrete

• 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.

• Drill Mounting: This bit features a universal 3/8" shank that fits directly into any standard corded or cordless power drill. No specialized adapters are required.
• Using the Locator Guide: Secure the included removable locator guide to the surface to ensure accurate positioning. The guide can also hold a small amount of water if you prefer wet drilling.
• Starting the Cut: If not using the guide, start at a slight angle to notch the material before bringing the tool upright.
• Operating Technique: Use high RPMs and light, controlled pressure. Let the laser-welded sintered diamonds do the cutting. Do not force the tool.
• Cooling: Although no water is required for cooling these sintered teeth, pausing periodically during deep cuts will help manage heat and extend tool life.

• HVAC Installations: The top choice for drilling large-diameter openings for exhaust vents, furnace ducting, and air intake pipes.
• Construction & Foundation: Ideal for passing through thick foundation slabs, concrete blocks, and foundation walls.
• Electrical & Utilities: Perfect for creating entry points for large conduit runs and electrical box cutouts in brick or stucco.
• Landscaping: Drilling through heavy-duty pavers and stone retaining walls for lighting or drainage.

Q: Do I need a pilot bit or a special adapter?
A: No. This tool is designed to drill directly without a pilot bit, and the 3/8" shank fits standard drills natively.

Q: Does this require water for cooling?
A: No. The diamond is sintered into laser-welded teeth, making it highly heat-resistant and optimized for dry drilling.

Q: Is the locator guide included?
A: Yes. For this 4-1/2 inch model, a precision locator guide is included in the package.

Q: Can I use this on glass or mirrors?
A: No. This tool is too aggressive for glass or mirrored surfaces. It is purpose-built for heavy-duty masonry and stone.
