1-3/8 Inch Diamond Hole Saw | 5/8"-11 Angle Grinder | Concrete & Tile

• Materials: Quartz, granite, concrete, brick, masonry, porcelain tile, ceramic tile, marble, and slate.
• Tool Compatibility: Direct mounting on 5/8"-11 threaded angle grinders. Compatible with standard power drills only if used with a separate hex adapter.
• Note: Not for use on glass, mirrored surfaces, or fragile decorative tiles.

• Angle Grinder Mounting: Thread the hole saw directly onto the 5/8"-11 spindle of your angle grinder. Ensure the connection is tight before operation.
• Starting the Cut: Start at a 45-degree angle to create a "crescent" notch. This prevents the bit from wandering. Once the groove is established, slowly tilt the tool to a 90-degree angle.
• You can also cut a guide out of scrap wood. that will hold and guide the tool in place.
• Operating Technique: Use high RPMs and light, steady pressure. Let the vacuum-brazed diamonds do the cutting; do not force the tool into the material.
• Heat Management: For deep cuts in stone or masonry, periodically back the bit out of the hole to clear dust and allow the air-cooled side slots to manage heat buildup.

• Kitchen & Bath Installation: Perfectly sized for installing standard faucet sets, soap dispensers, and water filtration taps in granite and quartz countertops.
• Plumbing Penetrations: Ideal for passing smaller copper or PEX supply lines through floor tiles and masonry.
• Renovation Projects: Core drilling for anchors or plumbing fixtures in porcelain, ceramic, and natural stone flooring.
• Masonry & HVAC: Creating clean entry points for utility lines in brick, block, and concrete walls.

Q: Does this fit a standard hand drill?
A: No. This bit features a 5/8"-11 threaded connection specifically for angle grinders. To use this with a standard power drill, a 5/8"-11 to Hex Shank adapter is required (sold separately).

Q: Can I use this for dry drilling?
A: Yes, the vacuum brazed technology is specifically engineered for dry jobsite conditions. While water is not required, it can be used to further extend tool life and reduce dust.

Q: What is the maximum drilling depth?
A: This hole saw has a maximum cutting depth of 1-3/8 inches, making it perfect for standard 3cm granite or quartz countertops and heavy-duty floor tiles.

Q: Is this suitable for glass?
A: We do not recommend this bit for glass or mirrored surfaces. For those applications, please see our Drilax Chrome Series bits designed for wet-drilling glass.
