Hole saw set Dedra DED1592SZ01 — diamond cutting cups 6, 8, 10, 12 mm with adapter

Diamond hole saw set Dedra DED1592SZ01 contains four diamond cutting cups with diameters 6, 8, 10 and 12 mm and an adapter, designed to create precise small-diameter holes in hard materials. The set is intended for controlled drilling in tile, ceramic, glass and natural or engineered stone. The diamond-coated cutting edges provide wear resistance and consistent performance when used with standard handheld drills or compatible rotary tools via the supplied adapter.

Advantages

The diamond cutting cups deliver clean, accurately sized holes with reduced chipping on fragile surfaces. The variety of diameters covers common small-hole needs for plumbing, fixtures and finishing work. The included adapter allows quick attachment to most drills and rotary tools, improving versatility. Durable diamond segments maintain cutting efficiency over repeated use on abrasive materials.

Suitable for

• Drilling holes for pipes and fittings in ceramic and porcelain tiles
• Making precise openings in glass and mirrors for small fasteners
• Creating holes in natural stone and engineered stone for finishing work
• DIY repairs and installations requiring small-diameter holes

Key specifications

• Cutting cup diameters: 6 mm, 8 mm, 10 mm, 12 mm
• Cutting edge: diamond-coated segments for abrasive materials
• Compatibility: handheld drills and rotary tools via included adapter
• Typical use materials: tile, ceramic, glass, natural and engineered stone
• Intended application: dry and low-speed wet drilling for precise small holes

How to use

Mark the drilling location and secure the workpiece to prevent movement. Fit the required diamond cup onto the adapter and tighten according to the tool manufacturer’s instructions. Start drilling at low speed with light, steady pressure; where applicable, use intermittent cooling or water supply to reduce heat and prolong tool life. Maintain a perpendicular angle for accurate, round holes. After cutting, stop the tool before removing the cup to avoid snagging the material.

Usage recommendations

Use low revolutions per minute and steady pressure when working with glass, porcelain and thin tiles. For hard stone and thicker tile, apply short cutting intervals with cooling to reduce overheating and extend diamond segment life. Wear appropriate eye protection and gloves, and secure small pieces to prevent movement during drilling.
