Diamond Core Drill Bit INDIAN PROFESSIONAL IP7708, M14 shank, 25 mm, dry drilling

Diamond core drill bit INDIAN PROFESSIONAL IP7708 with M14 shank and 25 mm cutting diameter is designed for dry drilling in hard finishing and construction materials. The bit is intended to create precise circular holes in ceramic, tile, porcelain and masonry during renovation, plumbing, electrical and HVAC installation work. Compatible with angle grinders and drills that accept M14-threaded accessories, the drill bit delivers concentrated cutting action for controlled hole making without the need for wet cooling.

Advantages

The diamond-segmented rim provides efficient cutting of hard surfaces while maintaining shape and diameter accuracy. A 25 mm cutting diameter allows standard hole sizes for pipe and conduit pass-throughs. The M14 threaded shank ensures secure mounting in most angle grinders and compatible rotary tools. The dry-drilling design avoids water management on site and simplifies use in interior renovation environments where wet cutting is impractical.

Suitable for

• Cutting holes in ceramic and porcelain tiles
• Drilling through masonry and thin brick
• Creating openings for plumbing pipes and electrical conduits
• Installation and repair tasks requiring precise round holes without wet cooling

Key specifications

• Cutting diameter: 25 mm
• Shank type: M14 threaded
• Drilling method: dry drilling
• Material compatibility: ceramic, porcelain, tile, masonry
• Application: angle grinders and drills with M14 accessory threads

How to use

Fit the M14 shank securely into an angle grinder or compatible rotary tool according to the tool manufacturer’s mounting instructions. Mark the centre point of the hole on the workpiece. Begin drilling at low speed to establish the cutting edge, then increase speed while applying steady, moderate pressure. Use short drilling intervals to reduce heat build-up and allow the bit to cool between passes. Avoid excessive force or continuous high-speed operation to extend tool life and maintain hole accuracy.

Usage recommendations

Wear appropriate personal protective equipment, including eye protection, dust mask and hearing protection. Secure the workpiece and clear loose debris during drilling. If dust suppression is required, use a vacuum extraction system designed for dry dust capture. Inspect the diamond segments periodically and replace the bit when cutting performance declines.
