Diamond Vacuum-Brazed Hole Saw Dedra DED1592S28 M14 28 mm

Diamond vacuum-brazed hole saw Dedra DED1592S28 M14 28 mm is a precision cutting tool designed to create clean round holes in hard and brittle materials. The tool features a 28 mm cutting diameter and an M14 shank compatible with drills and rotary tools that accept M14 adapters. The vacuum-brazed diamond edge provides durability and consistent cutting performance when working with ceramic, porcelain, glazed tiles, natural stone and similar surfaces where traditional carbide bits wear quickly.

Advantages

The vacuum-brazed diamond rim ensures continuous cutting action without the need for a segmented rim, reducing chipping and improving hole roundness. The M14 shank offers secure attachment to standard angle grinders and compatible drill adapters, allowing stable operation and accurate hole placement. This design balances cutting speed with tool life, providing repeatable results on demanding surfaces while minimizing the risk of overheating when used with recommended cooling practices.

Suitable for

• Drilling clean holes in ceramic and porcelain tiles
• Punching openings in natural stone and marble
• Creating penetrations in glazed or vitrified tile surfaces
• Making round holes for plumbing, electrical conduits and fixture fittings in hard surfaces

Key specifications

• Cutting diameter: 28 mm
• Shank type: M14 threaded shank for compatible power tools
• Cutting edge: vacuum-brazed diamond rim for continuous cutting
• Intended material types: ceramic, porcelain, stone, marble and similar hard surfaces
• Tool compatibility: angle grinders and drills with M14 adapter capability

How to use

Mark the hole position and secure the workpiece to prevent movement. Fit the hole saw onto a compatible tool with an M14 connection, ensuring the shank is tightened correctly. Begin drilling at low speed to establish the cut, then increase speed moderately while applying steady, light pressure. For best results and to extend tool life, use intermittent cutting and avoid excessive force; periodically withdraw the cutter to clear dust. Use water or a suitable coolant as needed to reduce heat build-up when working on dense stone or porcelain.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and dust mask. When cutting tile or stone, clamp the workpiece and consider backing fragile tiles with tape to minimize edge chipping. Apply light, steady pressure and cooling to prolong diamond life and maintain cutting accuracy.
