Hole saw Dedra 76 mm TCT 5/8" arbor (model 08X076)

Hole saw Dedra 76 mm TCT with a 5/8" arbor is a circular cutting tool designed to produce clean 76 mm diameter openings in a range of common building materials. The tool features tungsten carbide tipped (TCT) teeth for extended cutting life and consistent performance. It is intended for use with compatible handheld drills and drill presses to create holes for pipes, cables, locks and recessed fittings in wood, plywood, plastics and non-ferrous materials.

Advantages

The TCT tooth geometry provides enhanced wear resistance and retains sharpness over repeated cuts, reducing the need for frequent replacement. The 5/8" arbor connection ensures secure mounting in standard drill chucks and allows stable operation on both portable drills and bench-mounted drill presses. The saw’s design aims to deliver accurate 76 mm holes with minimal splintering when used with appropriate feed rates and backing support.

Suitable for

• Cutting 76 mm holes in soft and hardwoods
• Creating openings in plywood and laminated boards
• Drilling holes in plastics and composite panels
• Forming non-ferrous metal openings such as aluminum (thin sections)
• Installing plumbing pipes, electrical conduits, door locks and recessed fixtures

Key specifications

• Cutting diameter: 76 mm
• Tooth type: Tungsten carbide tipped (TCT)
• Arbor connection: 5/8"
• Recommended machine: Handheld drills and drill presses
• Suitable materials: Wood, plywood, plastics, non-ferrous materials

How to use

Secure the arbor into the drill chuck and tighten according to the drill manufacturer’s instructions. Mark the center of the intended opening and, if possible, use a pilot drill or center punch to prevent wandering. Begin cutting at moderate speed with steady, even pressure; avoid excessive feed force to prevent overheating or tooth damage. For laminated or veneered surfaces, place a sacrificial backing board under the workpiece to reduce splintering. After cutting, retract the saw while the drill is still turning briefly to clear chips, then power off and remove the workpiece.

Usage recommendations

Use coolant or periodic pauses for long cuts or when cutting dense materials to prolong tooth life. For best results on fragile surfaces, support the workpiece and use a lower speed setting. Inspect teeth before each use and replace the saw if teeth are chipped or excessively worn.
