Hole saw Dedra TCT 108 mm (5/8") universal for cutting metal and wood

Dedra TCT 108 mm (5/8") universal hole saw is a circular cutting tool designed to create precise round openings in a variety of materials. It features a tungsten carbide TCT cutting edge that delivers durability and maintains cutting performance when working on metal and wood. The 108 mm diameter and 5/8" arbor compatibility make this hole saw suitable for installations where clean, accurate holes are required, such as pipe and cable passages or ventilation duct connections during construction and renovation tasks.

Advantages

The tungsten carbide TCT teeth offer extended life and improved wear resistance compared with standard bi-metal blades, ensuring consistent cutting performance across different materials. The universal design allows cutting both metal and wood, reducing the need to change tools when switching tasks. The 108 mm diameter provides a standard opening size for many installation needs, while compatibility with a 5/8" arbor ensures easy mounting on common drill drivers and arbors.

Suitable for

• Creating openings for pipes and conduits in renovation and installation work
• Cutting holes for ventilation ducts and HVAC components
• Drilling round openings in wooden panels, doors and furniture
• Making holes in thin to medium-thickness metal sheets for routing cables or fittings

Key specifications

• Cutting diameter: 108 mm (nominal)
• Cutting edge material: tungsten carbide TCT
• Compatible arbor size: 5/8"
• Application materials: metal and wood
• Typical use: installation and renovation openings

How to use

Secure the hole saw onto a compatible 5/8" arbor and attach it to a suitable drill or drill driver. Mark the centre of the desired opening and, if possible, create a pilot point to stabilise the tool. Start drilling at low speed to establish the cut, then increase speed moderately while applying steady, even pressure. For metal cutting, use cutting fluid or coolant where appropriate and avoid excessive feed force to prevent damage to teeth. After completing the cut, withdraw the hole saw and clear any material debris from the teeth before further use.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses and gloves. Use a drill with sufficient power and a stable grip. For best results on metal, use cutting lubricant and moderate speed; for wood, higher speeds can be used with controlled pressure. Inspect the cutting edge regularly and replace the hole saw if teeth are damaged or excessively worn.
