Vacuum-brazed diamond core drill bit Dedra DED1592S68, 68 mm, M14 shank

Vacuum-brazed diamond core drill bit Dedra DED1592S68, 68 mm, M14 shank is designed for drilling precise, clean holes in hard materials such as concrete, natural stone and masonry. The vacuum-brazed diamond segments ensure continuous exposure of diamond grains during use, maintaining cutting performance and extending service life compared with conventional bonded bits. The M14 threaded shank fits angle grinders and rotary tools that accept M14 accessories, allowing use in common construction and renovation tasks.

Advantages

The vacuum-brazed bond delivers consistent cutting action and improved durability on reinforced concrete and other abrasive substrates. A 68 mm cutting diameter provides a standard hole size for installations and penetrations while the M14 shank ensures secure attachment to compatible machines. The overall geometry and segment design reduce clogging and help produce cleaner edges in drilled holes, lowering the need for additional finishing.

Suitable for

• Drilling through concrete, natural stone and masonry
• Creating holes for plumbing, electrical and HVAC penetrations
• Tile and bathroom renovation where a clean circular cut is required
• On-site construction where angle grinders with M14 threads are used

Key specifications

• Cutting diameter: 68 mm
• Shank type: M14 threaded shank for angle grinders and compatible rotary tools
• Bonding method: vacuum-brazed diamond segments for continuous grain exposure
• Suitable materials: concrete, natural stone and masonry
• Intended use: dry drilling with angle grinders; compatible with machines accepting M14 accessories

How to use

Securely attach the M14 shank to a compatible angle grinder or rotary tool according to the tool manufacturer's instructions. Mark the drilling position and, when possible, start at low speed to establish the hole. Apply steady, moderate pressure and maintain consistent rotation speed; avoid excessive force that can overheat the bit. For deeper holes, withdraw periodically to clear debris and allow cooling. Use appropriate personal protective equipment including eye protection, dust mask and hearing protection.

Usage recommendations

For best performance, use the drill bit primarily for dry drilling with machines that accept M14 accessories and avoid prolonged continuous operation without pauses to prevent overheating. When drilling reinforced concrete, progress slowly and use intermittent withdrawal to remove slurry and debris. Match the machine power and speed to the application and always follow safety guidance for angle grinder use.
