Hole saw Dedra 80 mm HM with HEX shank DED1506-X

Carbide-tipped hole saw Dedra 80 mm HM with HEX shank DED1506-X is a cutting tool designed to create clean, round openings with an 80 mm diameter in materials appropriate for hard-metal (HM) teeth. The hole saw features HM (hard metal) cutting edges for enhanced wear resistance and a HEX shank that fits into drills and drivers with a compatible HEX chuck, making it suitable for installation and renovation tasks that require a reliable circular cut.

Advantages

The HM teeth provide higher abrasion resistance and a longer life span compared with standard high-speed steel teeth when used on suitable materials. The 80 mm diameter produces precise, consistent holes for pipes, conduits or fittings, while the HEX shank ensures secure engagement in hex chucks and reduces slippage during drilling. The tool’s construction facilitates stable cutting and straightforward replacement when the cutter wears out.

Suitable for

• Creating 80 mm diameter openings for pipes and conduits
• Cutting holes for locks, door hardware or mounting plates
• Making cable pass-throughs in walls, floors or panels
• Renovation and installation work in construction settings

Key specifications

• Cutting diameter: 80 mm
• Cutting edge material: carbide-tipped (hard metal / HM)
• Shank type: HEX shank for hex chucks
• Intended use: drilling round openings in materials compatible with HM teeth

How to use

Mount the hole saw onto a compatible arbor or directly into a drill/driver equipped with a HEX chuck, ensuring the connection is secure before operation. Mark the center of the desired opening and use a pilot bit or center punch where appropriate to guide the tool. Start drilling at low speed to establish the cut, then increase speed moderately while applying steady, even pressure. Use intermittent withdrawal to clear chips and avoid overheating. After cutting, remove the core and inspect the teeth for wear before subsequent use.

Usage recommendations

Use appropriate personal protective equipment (eye protection, gloves and hearing protection) and select drill speeds and feed rates suitable for the work material. For prolonged life of the HM teeth, avoid excessive heat build-up by using coolant or applying intermittent cutting in abrasive or dense materials. Verify compatibility of the HEX shank with the tool chuck and ensure the workpiece is securely clamped before cutting.
