Hole saw Dedra TCT 40 mm 5/8" for cutting metal and wood

Dedra TCT hole saw 40 mm with a 5/8" arbor connection is a bi-material cutting tool with tungsten carbide-tipped teeth, designed for creating precise circular openings in wood, non-ferrous metals and composite materials. Intended for use with handheld drills and drill drivers, this hole saw combines a compact 40 mm cutting diameter with robust tooth geometry to deliver consistent cutting performance for plumbing, electrical and general installation work.

Advantages

The TCT (tungsten carbide-tipped) teeth increase wear resistance and maintain cutting sharpness over extended use, reducing the need for frequent replacements. The 5/8" arbor connection provides secure mounting to standard drill chucks and arbor systems, ensuring stable rotation and reduced wobble. Its 40 mm diameter offers a balance between accessibility and material removal, enabling neat, round holes with minimal tear-out when used with appropriate pilot drills and proper feed rates.

Suitable for

• Cutting circular openings in soft and hardwoods
• Drilling holes in non-ferrous metals such as aluminium and copper
• Making pass-throughs for pipes and cables in installation work
• Preparing openings in composite panels and laminated boards

Key specifications

• Cutting diameter: 40 mm
• Arbor connection: 5/8" (5/8-inch)
• Tooth type: tungsten carbide-tipped (TCT)
• Compatible tool: handheld drills and drill drivers
• Typical applications: wood, non-ferrous metals, composites

How to use

Mount the hole saw onto a compatible arbor and secure it in the drill chuck according to the drill manufacturer's instructions. Mark the centre of the intended hole and, if available, use a pilot bit to guide the saw and reduce wandering. Start drilling at low speed to establish the cut, then increase speed moderately while maintaining steady axial pressure. Withdraw the cutter periodically to clear chips and prevent overheating. After cutting, remove any burrs from the hole edges with a file or deburring tool.

Usage recommendations

Use cutting lubricant or coolant when working with metals to prolong tool life. Match drill speed and feed to the material: lower speeds for metals and higher speeds for wood. Wear appropriate personal protective equipment including eye protection and gloves. Replace the hole saw when tooth wear noticeably reduces cutting performance or produces excessive heat.
