Hole saw Dedra 08W035, diameter 3.5 cm, for metal, stainless steel, aluminium, plastic, wood

Hole saw Dedra 08W035 has a cutting diameter of 3.5 cm and is designed for drilling precise circular openings in a range of materials including metal, stainless steel, aluminium, plastic and wood. Supplied as a single unit for use with compatible drill chucks and arbor adapters, this hole saw is intended for general construction, electrical installations, HVAC, plumbing and DIY tasks where neat, repeatable round cutouts are required.

Advantages

The bi-material cutting edge and robust body provide consistent performance across different materials while maintaining a compact 3.5 cm diameter for small to medium openings. The tool is suitable for use with standard drill power tools when paired with the appropriate arbor, and its construction minimises deformation and improves centring during cutting. Lightweight and simple to mount, the hole saw allows relatively fast hole-making with reduced need for template work.

Suitable for

• Creating conduit and cable entry points in electrical installations
• Cutting openings for pipes and fittings in plumbing and HVAC work
• Drilling access holes in metal sheets and stainless-steel panels
• Making holes in aluminium profiles and plastic components
• DIY projects and furniture modifications requiring precise round cutouts

Key specifications

• Cutting diameter: 3.5 cm
• Compatible materials: metal, stainless steel, aluminium, plastic, wood
• Supply format: single hole saw unit (requires compatible chuck or arbor)
• Typical use: hand-held or bench drilling with appropriate arbor and pilot bit

How to use

Secure the hole saw to a compatible arbor or chuck and ensure the pilot bit is fitted and centered before starting. Mark the centre of the desired hole on the workpiece, clamp the workpiece to prevent movement, and set the drill to an appropriate speed for the material being cut. Begin drilling with steady, moderate pressure, allowing the teeth to cut and clearing chips periodically to avoid clogging. After completing the cut, retract the tool slowly and remove any remaining slug and burrs from the hole edges before final finishing.

Usage recommendations

Use appropriate personal protective equipment including eye protection and gloves. For metal and stainless steel, use cutting oil or coolant and lower RPM to extend tool life. For plastic and wood, higher speeds are typically acceptable but keep feed moderate to prevent melting or splintering. Ensure compatibility between the hole saw and your drill’s arbor and follow the drill manufacturer’s safety guidelines.
