1-3/8 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 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.

• Plumbing & HVAC: Ideal for 1-inch pipe sleeves, radiator pipes, and running PEX or copper supply lines through exterior walls.
• Electrical Utilities: Perfect for creating entry points for 1-1/4" conduit or large-diameter service entrance cables.
• Bathroom & Kitchen: Precise drilling for faucet installations in granite, marble, or quartz countertops where a slightly larger clearance is needed.
• Masonry & Anchoring: Create clean passages for structural anchors and exterior utility connections through brick, stucco, and slate.

• Hole Diameter: 1-3/8 inches
• Cutting Depth: 2 inches
• Shank Type: 3/8 inch Universal Round Shank
• Construction: Turbo Diamond Segments Laser-Welded to Steel Body

Q: Can I use this bit with a regular cordless drill?
A: Yes, the 3/8 inch shank is designed to fit standard cordless and electric hand drills.
Q: What makes the "Turbo Segment" different?
A: The turbo design features a corrugated-style diamond edge that reduces friction and clears dust faster, resulting in cooler, quicker cuts.
Q: Is water cooling required?
A: No. This is a heavy-duty dry core bit. However, using water can extend the life of the bit when drilling exceptionally hard materials.
Q: How deep can I drill?
A: This bit is designed for a maximum drilling depth of 2 inches, perfect for walls and slabs.
