Hole saw Dedra 08X146, diameter 14.6 cm, single piece

Hole saw Dedra 08X146 with a cutting diameter of 14.6 cm is a single-piece tool designed to create large circular openings in softer construction materials. It is intended for use with compatible drills and drill drivers to cut through wood, plastics and soft panel materials. The tool's dimensions and cutting diameter make it suitable for tasks such as installing vents, recessed light fixtures, pipe penetrations and cable passages where a clean, round opening is required.

Advantages

The hole saw provides a precise 14.6 cm cutting diameter in a single, durable unit that simplifies setup and use with standard drill chucks. Its geometry is optimized for cutting softer substrates while reducing chipping and tear-out on the material edges. Being a single-piece tool, it offers straightforward installation on compatible drill arbors and requires minimal maintenance after use.

Suitable for

• Cutting circular openings in wood boards and plywood
• Routing holes in plastic sheets and PVC panels
• Creating penetrations for ventilation grilles and ducting
• Installing recessed lighting housings and ceiling fixtures
• Making openings for pipes, conduits and cable entries

Key specifications

• Cutting diameter: 14.6 cm
• Configuration: single-piece hole saw
• Material compatibility: wood, plastics, soft panels
• Drive compatibility: designed for use with drill and drill driver chucks
• Typical application: large circular openings for installation work

How to use

Secure the hole saw to a compatible arbor or drill chuck according to the drill manufacturer's instructions. Mark the center point of the required opening on the workpiece and clamp the material to prevent movement. Start drilling at low speed to establish the pilot position, then increase speed moderately while maintaining steady pressure. Allow the tool to cut without forcing; periodically withdraw to clear debris if necessary and to avoid overheating. After cutting, deburr the edge as required for a clean finish.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Select drill speeds suitable for the material being cut—lower speeds for denser or thicker panels—and avoid excessive feed force to prolong tool life. Ensure the workpiece is well supported and use clamps to prevent movement during cutting.
