## Long description

Diamond brazed hole saw Dedra DED1592S20 with M14 thread and 20 mm cutting diameter is a vacuum-brazed cutting cup designed for creating precise circular holes in hard surfaces. The tool features diamond abrasive bonded to a metal body using vacuum brazing, which ensures an even, durable cutting edge suitable for tile, ceramic, porcelain and natural stone. It is intended for use with angle grinders or rotary tools fitted with an M14 arbor to perform drilling tasks in construction, renovation and installation work.
Advantages
The vacuum-brazed diamond layer provides consistent cutting performance and long service life, reducing the need for frequent tool changes. The metal body with M14 thread allows secure mounting on compatible angle grinders and rotary tools, providing stable operation and controlled cutting. The compact 20 mm diameter cutting cup produces clean, circular holes with minimal chipping when used at recommended speeds and with appropriate coolant or wet cutting techniques.
Suitable for
Drilling holes in ceramic and porcelain tiles
Cutting circular openings in natural stone and granite
Creating access holes for pipes and fixtures during renovation
Installing electrical boxes or conduits in tiled surfaces
Key specifications
Cutting diameter: 20 mm
Mount type: M14 threaded arbor
Construction: vacuum-brazed diamond abrasive on metal cup
Compatible tools: angle grinders and rotary tools with M14 connection
Typical applications: dry or wet drilling in hard brittle materials
How to use
Securely mount the diamond brazed cutting cup onto the M14 arbor of a compatible angle grinder or rotary tool. Mark the center point of the hole on the workpiece, then start the tool at low speed to establish the initial cut and prevent slipping. Apply steady, moderate pressure and maintain a consistent angle while drilling. For tile and porcelain, use intermittent cooling with water or perform the cut under light wet conditions where possible to extend tool life and reduce dust. After cutting, clean the hole and inspect the edge for any residual chipping.
Usage recommendations
Use appropriate personal protective equipment, including safety glasses, gloves and a dust mask. For best results on ceramic, porcelain and natural stone, employ light water cooling and avoid excessive force or high speeds that can overheat the diamond bond. Replace the cutting cup when wear reduces cutting efficiency to prevent damage to the workpiece.
