Hole saw Dedra 08W030 — 3 cm diameter, for metal, stainless steel, aluminium, plastic, wood

Dedra 08W030 is a single-piece hole saw with a 3 cm cutting diameter designed to produce clean circular openings across a variety of common construction and installation materials. The tool is compatible with standard drills and drill drivers and is intended for tasks such as creating holes for pipes, cable entries, fittings and mounting points in metalworking, general construction and renovation work.

Advantages

The one-piece construction provides stable cutting and reduces the risk of misalignment during operation. A 3 cm diameter offers a compact solution for small to medium penetrations where precision and a neat finish are required. The cutting geometry is suitable for use on diverse materials including metal, stainless steel, aluminium, plastic and wood, allowing a single tool to serve multiple applications. Its design permits attachment to common drill chucks and drill drivers for convenient, powered use.

Suitable for

• Cutting holes for pipes and conduits
• Creating cable and wiring entry points
• Installing fittings, sockets and ventilation outlets
• General metalworking and sheet metal penetration
• Woodworking and plastic panel openings

Key specifications

• Cutting diameter: 30 mm
• Construction: single-piece hole saw
• Compatible drive: standard drill chuck / drill driver
• Applicable materials: carbon steel, stainless steel, aluminium, plastic, wood
• Intended use: cutting circular openings for installation and assembly tasks

How to use

Select a suitable drill or drill driver with an appropriate chuck and secure the hole saw according to the drill manufacturer's instructions. Mark the centre point of the desired hole, clamp the workpiece if possible, and start drilling at low speed to establish the pilot contact. Increase speed steadily while applying moderate, consistent pressure; avoid forcing the tool. For metal and stainless steel, use cutting lubricant or coolant to reduce heat and extend tool life. After cutting, remove burrs and clean the edge of the hole for a neat finish.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For best results on hard metals, employ cutting fluid and periodically withdraw the saw to clear chips. Ensure the drill is held steady and the workpiece is securely clamped to minimise vibration and achieve an accurate round opening.
