Diamond Core Drill Bit M14 12 mm for Dry Drilling, INDIAN PROFESSIONAL IP7704

Diamond Core Drill Bit M14 12 mm for Dry Drilling, INDIAN PROFESSIONAL IP7704 is a coronet-style diamond-tipped bit with a 12 mm cutting diameter and an M14 threaded connection intended for dry drilling in hard materials. It is manufactured for use with handheld drills and compatible rotary tools that accept an M14 mandrel. The design focuses on creating precise small-diameter holes without the need for water cooling, enabling installation tasks and sample extraction where wet drilling is impractical.

Advantages

The diamond cutting edge provides high hardness and wear resistance for effective penetration of dense materials. The coronet geometry reduces contact area and minimizes friction during dry operation, helping to maintain drilling accuracy. The M14 threaded shank ensures secure mounting in compatible chucks and adapters. Its compact 12 mm diameter is suitable for precise anchor and conduit hole preparation while keeping chip volume low for easier cleanup.

Suitable for

• Drilling small-diameter holes in concrete and masonry without water
• Installing anchors and fixings in walls and floors
• Creating passages for electrical conduit and plumbing in hard substrates
• Collecting core samples or creating pilot holes for larger coring
• Use with handheld rotary drills and angle grinders fitted with M14 adapters

Key specifications

• Cutting diameter: 12 mm
• Connection type: M14 threaded shank
• Drilling mode: Dry drilling (no water cooling)
• Tip: Diamond-segment coronet design for hard materials
• Typical applications: Concrete, masonry, stone, and other dense substrates

How to use

Mount the drill bit securely in a compatible M14 chuck or adapter, ensuring the threaded connection is fully engaged and tightened. Mark the drilling position and start the drill at low speed to establish a pilot seat, then increase speed and apply steady, moderate pressure. Avoid excessive axial force or high speeds that could generate excessive heat; use intermittent drilling to allow the bit to clear debris and cool. Periodically withdraw the bit to remove dust and chips. Because this bit is intended for dry drilling, do not introduce water during use.

Usage recommendations

For best results, use drills with variable speed control and a side handle for stability. Wear appropriate personal protective equipment including eye protection, dust mask, and hearing protection. If drilling very hard or reinforced concrete, reduce speed and use short drilling intervals to limit heat build-up and extend tool life.
