## Long description

Diamond corers set Dedra DED1592SZ05 — 28 mm, 35 mm, 68 mm contains three diamond hole saws designed for drilling precise circular openings in hard, brittle materials such as ceramic tile, porcelain, natural stone and glass. Each corer has a continuous diamond-coated cutting rim that provides a longer service life and more consistent cutting performance than standard HSS or carbide hole saws. The set is intended for use with rotary drills and drill drivers equipped with an appropriate arbor and water or coolant where required to reduce heat and prolong tool life.
Advantages
The diamond-coated rims deliver cleaner edges and reduced chipping when cutting fragile surfaces. The set includes three commonly used diameters—28 mm, 35 mm and 68 mm—covering typical needs for plumbing, electrical and finishing penetrations. Designed for compatibility with standard arbor systems and rotary drills, these corers offer stable cutting and extended durability in abrasive or hard materials. Using a diamond cutting surface reduces the need for repeated passes and improves hole roundness compared with conventional metal bits.
Suitable for
 Drilling holes in ceramic and porcelain tiles for pipe and fixture pass-throughs
 Creating openings in natural stone and engineered stone for faucets and fittings
 Cutting circular holes in glass and glazed surfaces for lighting or cable entries
 Plumbing and sanitary installations that require precise circular penetrations
 Electrical and HVAC installations where neat, accurate holes are required
Key specifications
 Diameters: 28 mm, 35 mm, 68 mm
 Cutting edge: continuous diamond-coated rim for hard, brittle materials
 Intended drive: rotary drill or drill driver with compatible arbor
 Material compatibility: ceramic tile, porcelain, natural stone, engineered stone, glass
 Cooling: recommended use of water or coolant to reduce heat and dust
How to use
Secure the appropriate diamond corer to a compatible arbor and mount it on a rotary drill with steady torque control. Mark the drilling location and start at low speed to create a pilot scoring groove, applying light, even pressure. For tile and glass, use water or a coolant stream to keep the cutting edge cool and to remove slurry; this improves cutting efficiency and extends tool life. Increase speed moderately once the rim has established a groove, and maintain steady, controlled motion until the hole is complete. Avoid excessive axial force and do not overheat the corer to prevent premature wear.
Usage recommendations
For best results, clamp workpieces where possible, use a drill with variable speed and a compatible arbor, and apply continuous water cooling when cutting tile, stone or glass. Wear appropriate personal protective equipment, including eye protection and a dust mask, and proceed with steady, moderate pressure to achieve clean, accurate holes.
