1-1/4 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.

• Electrical & Lighting: Ideal for creating precise pass-throughs for conduit and specialized wiring in stone or tile walls.
• Kitchen & Bath: Perfectly sized for smaller plumbing lines, soap dispensers, or filtered water taps in granite and quartz countertops.
• Renovation Work: Core drilling for anchors or plumbing fixtures in porcelain, ceramic, and natural stone flooring.
• Masonry: Cleanly piercing through brick, block, and non-reinforced concrete for utility access.

Q: Does this fit a standard hand drill?
A: This bit features a 5/8"-11 threaded connection designed specifically for angle grinders. To use this with a standard 3/8" or 1/2" power drill chuck, 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 engineered for high-speed dry drilling. Using water as a coolant is optional but will extend the life of the bit and provide a cleaner cut.

Q: What is the maximum drilling depth?
A: This hole saw has a 1-3/8 inch depth of cut, which is ideal for standard countertops, floor tiles, and masonry pavers.

Q: Can I use this on glass?
A: We do not recommend this specific brazed bit for delicate glass or mirrors. For those materials, our Chrome Series wet-drilling bits are the preferred choice.
