Hole saw DEDRA HW4072 diameter 7.2 cm 1 pc

The DEDRA HW4072 hole saw with a 7.2 cm cutting diameter is a single-piece accessory intended for creating circular holes in a range of construction and installation materials. Designed to be fitted to compatible arbors or drill chucks, this hole saw supports tasks that require accurate round openings, such as pipe penetrations, cable routing, and installing fixtures. The tool’s construction balances cutting performance and service life for both professional tradespeople and DIY users.

Advantages

This hole saw provides a precise 7.2 cm cutting diameter, enabling consistent round holes with clean edges. Its single-piece configuration simplifies setup and reduces the number of components to manage. The tool is built to withstand repeated use and maintain cutting efficiency over time, minimizing the need for frequent replacement. Compatibility with standard drill attachments allows rapid integration into existing tool sets.

Suitable for

• Cutting round openings for pipes and conduits
• Creating holes for electrical boxes and cable pass-throughs
• Installing ventilation or plumbing fixtures requiring circular cutouts
• General woodworking and non-ferrous material hole cutting where a 7.2 cm aperture is needed

Key specifications

• Cutting diameter: 72 mm
• Quantity: 1 piece
• Material: hardened cutting edge suitable for general construction materials (wood, soft plastics, non-ferrous metals — depending on blade type)
• Compatibility: designed for use with standard hole saw arbors and drill chucks
• Intended use: manual and power drilling applications

How to use

Install the hole saw on a compatible arbor or in the drill chuck according to the drill and arbor manufacturer’s instructions. Mark the centre point of the required hole, secure the workpiece to prevent movement, and position the pilot bit or guide at the centre mark. Start drilling at low speed to establish the cutting path, then increase speed as appropriate for the material. Apply steady, moderate pressure and allow the hole saw to cut without forcing. After completing the cut, withdraw the saw and clear cut material or debris from the cavity and teeth before further use.

Recommendations

Use appropriate personal protective equipment (eye protection, gloves, and hearing protection). Select the correct drill speed and feed for the material being cut, and ensure the workpiece is properly clamped. For metal or harder materials, verify that the hole saw’s cutting edge is suitable or consider using a dedicated metal-cutting variant. Regularly inspect the cutting teeth for wear and clean debris to maintain cutting performance.
