Hole saw Dedra 08W140, 14 cm diameter, for metal, stainless steel, aluminium, plastic, wood

Hole saw Dedra 08W140 with a 14 cm diameter is a single-piece cutting accessory designed to create large circular openings in a variety of materials. Compatible with suitable drill drivers and arbor holders, this hole saw is intended for tasks that require precise round cuts in metal, stainless steel, aluminium, plastic and wood. Its wide 14 cm cutting diameter makes it suitable for installing pipes, vents, large electrical boxes and other through-holes where a clean circular cut is required.

Advantages

The design of this Dedra hole saw provides a stable cutting path and consistent diameter control during operation. Constructed for use on both ferrous and non-ferrous metals as well as softer materials like plastic and wood, it reduces the need for multiple blade types on mixed-material jobs. Supplied as a single robust piece, it can be mounted on compatible arbors or drill drivers to deliver efficient hole cutting while minimising vibration when used with appropriate speeds and support.

Suitable for

• Creating openings for plumbing and HVAC pipework
• Cutting holes for large electrical junctions and mounting boxes
• Fabrication and modification of metal or aluminium panels
• Installing vents, ducts and ducting collars
• Carpentry tasks requiring large circular cuts in wood or plastic

Key specifications

• Cutting diameter: 140 mm
• Compatible materials: metal, stainless steel, aluminium, plastic, wood
• Form factor: single-piece hole saw
• Intended mounting: compatible with standard drill arbors/drivers

How to use

Fit the hole saw securely to a compatible arbor or drill driver according to the arbor manufacturer’s instructions. Mark the centre point of the required opening and pilot-drill if necessary to guide the hole saw. Use steady, even pressure and an appropriate rotational speed for the material being cut; reduce speed when cutting metals such as stainless steel and increase cooling or use cutting fluid as required. Support the workpiece to prevent flexing and clear chips frequently to maintain cutting efficiency. After cutting, deburr the edge as needed for a clean finish.

Usage recommendations

For best results, select an arbor and pilot bit rated for the material type and ensure the drill has sufficient power and torque. When cutting metals, use cutting fluid and lower speeds to extend tool life. For plastics and wood, moderate speed and minimal pressure reduce the risk of melting or splintering. Always follow safety procedures including eye protection, gloves and secure clamping of the workpiece.
