Diamond core drill bit Dedra DED1592S72 72 mm with M14 thread

Diamond core drill bit Dedra DED1592S72 72 mm with M14 thread is a segmented diamond-tipped core bit engineered for cutting precise circular holes in hard construction materials. The 72 mm cutting diameter and diamond edge are optimized for drilling through tiles, masonry, ceramics and similar finishes when used with rotary tools or drills that accept an M14 threaded connection. The product is intended for wet or cooled operation to maintain cutting efficiency and extend service life.

Advantages

The diamond cutting segments deliver high abrasion resistance and consistent hole quality across hard substrates. The 72 mm diameter provides a standardized size for common plumbing and electrical penetrations. The threaded M14 connection ensures secure mounting on compatible rotary tools and angle grinders, reducing wobble during cutting. When used with appropriate cooling, the bit offers improved longevity and reduced risk of thermal damage to both tool and workpiece.

Suitable for

• Drilling holes for plumbing pipes and fixtures through tile and masonry
• Creating openings for electrical boxes and conduit in walls and floors
• Cutting precise circular holes in ceramic, porcelain and natural stone tiles
• General core drilling in concrete and brick when diamond tooling is required

Key specifications

• Cutting diameter: 72 mm
• Connection type: M14 threaded mount (for compatible rotary tools)
• Tip material: diamond segments for hard material cutting
• Typical use: wet or cooled drilling to extend tool life
• Application materials: tile, ceramic, porcelain, masonry, concrete

How to use

Secure the diamond core drill bit onto a compatible tool with an M14 threaded arbor following the tool manufacturer's instructions. Mark the center point of the hole on the work surface and begin drilling at low speed to establish the cutting groove, then increase speed as appropriate for the material. Apply steady, even pressure without forcing the bit; allow the diamond segments to cut at their designed rate. Use water or a cooling system to reduce heat and remove debris during cutting, particularly when working with dense or abrasive materials.

Usage recommendations

Use protective equipment including eye and hand protection. For best results and longer life, operate with a continuous supply of coolant or intermittent water flow, avoid excessive lateral forces, and match drilling speed to the material hardness. Inspect the bit for wear before each use and replace when diamond segments are significantly worn or the diameter tolerance is compromised.
