Hole Saw DEDRA 0791 for Wood and Plasterboard 1 pc

The DEDRA 0791 hole saw for wood and plasterboard is a single-piece cutting accessory designed to create clean, accurate circular openings in timber and gypsum board. Constructed for routine carpentry and installation tasks, this hole saw offers a straightforward solution for cutting passage holes for pipes, cables, recessed fixtures and ventilation outlets without the need for complex setup.

Advantages

The tool provides a robust cutting edge and a rigid body that help maintain concentric cuts and reduce wobble during drilling. Its single-piece design simplifies mounting and handling, while compatible tooth geometry enables efficient material removal in both soft and medium-density substrates. The hole saw’s construction supports repeated use in workshop and on-site environments with minimal maintenance required.

Suitable for

• Cutting circular openings in wood panels and boards
• Making holes in plasterboard for electrical boxes, sockets and lights
• Creating feed-throughs for pipes, conduits and cables
• General carpentry and renovation tasks requiring clean round cuts

Key specifications

• Intended materials: wood and plasterboard
• Configuration: single-piece hole saw
• Typical mounting: compatible with standard drill arbors or mandrels (verify arbor fit before use)
• Cut type: circular holes for through-work
• Durability: designed for repeated use in light to medium-duty applications

How to use

Secure the hole saw to an appropriate arbor and tighten according to the arbor manufacturer’s instructions. Mark the center point of the intended hole and, where possible, use a pilot drill or center punch to guide the saw. Start drilling at low speed to establish the cut, then increase speed gradually while applying steady, moderate pressure. Withdraw periodically to clear debris and prevent clogging. After cutting, remove rough edges from the hole with sandpaper or a file.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Match the hole saw size and arbor to your drill, and avoid excessive feed pressure to prolong cutting life. For cleanest results in plasterboard, back the panel where possible to minimize tear-out. Inspect the cutting edge before use and replace the hole saw if teeth are damaged or excessively worn.
