Diamond Core Bit M14 35 mm for Dry Drilling, INDIAN PROFESSIONAL IP7711

Diamond Core Bit M14 35 mm for Dry Drilling, INDIAN PROFESSIONAL IP7711 is a precision diamond cutting tool with a 35 mm cutting diameter and an M14 threaded connection. Designed for dry drilling, this core bit is intended to make accurate circular holes in hard surfaces such as ceramic tile, porcelain, natural stone and other similar materials when used with M14-shank angle grinders or compatible rotary tools. The tool is suitable for professional tradespeople and DIY users who need a compact diamond core solution for finishing work and repair tasks.

Advantages

The diamond cutting edge provides efficient material removal and consistent hole quality when used for dry drilling. The M14 threaded connection offers broad compatibility with common angle grinders and rotary tools, enabling a fast tool change and stable attachment. The compact 35 mm diameter is suited to applications requiring small, accurately placed holes without excessive material loss. The construction balances cutting performance with wear resistance for repeated use on hard surfaces.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Creating openings in natural stone and engineered stone
• Small installation and repair tasks in bathrooms and kitchens
• Precision cutting for fixtures, anchors and pipe passages

Key specifications

• Cutting diameter: 35 mm
• Connection thread: M14
• Drilling method: dry drilling
• Cutting material: diamond segments
• Intended materials: tile, ceramic, stone and similar hard surfaces

How to use

Attach the core bit securely to an M14-shank angle grinder or compatible rotary tool. Mark the desired hole position and start drilling at low speed to create a guide groove, then increase speed steadily while applying light, even pressure. Keep the tool stable and avoid lateral forces to maintain hole accuracy. Because this bit is designed for dry drilling, do not use water cooling; monitor the bit and material temperature and allow short pauses if overheating occurs. Finish the hole with light passes until the core is cut through.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, dust mask and hearing protection. Secure the workpiece before drilling and work in a well-ventilated area. For extended service life, avoid excessive pressure and allow the bit to cool periodically during prolonged use.
