Hole saw (core drill) Dedra DED1506-2 80 mm, carbide-tipped, SDS+ and HEX shank

Dedra DED1506-2 is an 80 mm carbide-tipped hole saw (core drill) designed for cutting circular openings in construction and installation tasks. The tool has a hardmetal (HM) cutting edge for longer wear and cleaner hole edges. It is supplied with two shank types — SDS+ and HEX — so it can be fitted to compatible rotary hammers and quick-change chucks, offering flexibility across different drills and applications.

Advantages

The carbide-tipped rim provides enhanced durability compared with standard bi-metal teeth and maintains cutting performance when working with abrasive or mixed materials. Dual shank compatibility (SDS+ and HEX) allows rapid adaptation between hammer drilling and conventional drilling setups without changing the cutter. The 80 mm diameter is suitable for common installation tasks where precise, round openings are required, and the solid construction supports stable cutting and reduced wobble.

Suitable for

• Creating cable and pipe entries in walls and panels
• Installing electrical boxes and conduits
• Making circular openings in masonry, plaster, and mixed materials where a carbide edge is beneficial
• Retrofit and renovation works that require repeatable, clean holes

Key specifications

• Cutting diameter: 80 mm
• Cutting edge material: carbide (hardmetal, HM)
• Shank types included: SDS+ and HEX
• Tool type: hole saw / core drill

How to use

Fit the appropriate shank (SDS+ for rotary hammer mode or HEX for quick-change chucks) into the drill according to the drill manufacturer's instructions. Mark the centre of the opening, position the hole saw square to the work surface, and start drilling at low speed to establish the cut. Apply steady pressure without forcing the tool; increase speed as the cutter engages. Withdraw periodically to clear debris and avoid overheating. After cutting, remove the core and deburr the hole if necessary.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Select a drill that supports the chosen shank type and use operating modes recommended for the work material (hammer mode for masonry when compatible). For prolonged cutting or dense materials, allow cooling pauses and clear chips regularly to extend tool life and maintain cutting quality.
