Diamond Core Bit INDIAN PROFESSIONAL IP7717 85 mm M14 for Dry Drilling

Diamond Core Bit INDIAN PROFESSIONAL IP7717 85 mm M14 for Dry Drilling is a segmented diamond drill bit designed for creating precise holes in hard materials. The 85 mm cutting diameter and standard M14 thread allow attachment to compatible rotary tools and angle grinders. Intended for dry drilling, this core bit is suitable for tasks where diamond tooling is required to cut through dense surfaces such as ceramic, porcelain, brick and similar masonry materials.

Advantages

This diamond core bit offers a durable segmented rim that maintains cutting efficiency during dry operation. Its construction provides stable guidance and reduced vibration when mounted on tools with an M14 connection. The 85 mm diameter delivers a clean hole size for common installation tasks while the diamond segments ensure long-lasting cutting performance on abrasive, hard substrates.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Creating openings in brick and concrete masonry
• Installing plumbing and electrical fixtures in tiled or masonry surfaces
• Dry drilling where water cooling is impractical or not available

Key specifications

• Cutting diameter: 85 mm
• Thread type: M14 compatible
• Drilling method: dry
• Segmented diamond rim for cutting hard materials
• Intended tool type: rotary tools and angle grinders with M14 mount

How to use

Secure the core bit to a compatible rotary tool or angle grinder using the M14 thread. Mark the drilling position on the workpiece and start the tool at low speed to establish a stable contact point. Apply steady, moderate pressure and maintain a consistent orientation to avoid tilting; allow the diamond segments to do the cutting rather than forcing the bit. For extended drilling sessions, pause periodically to let the tool and bit cool down. Follow the tool manufacturer's safety instructions and wear appropriate personal protective equipment.

Usage recommendations

Use this core bit for dry applications on hard, non-metallic surfaces. Avoid excessive side loading and prolonged continuous operation without breaks to extend diamond segment life. Inspect the cutting edge before use and replace the bit if segments are worn or damaged.
