Hole saw Dedra TCT 57 mm (5/8") universal

Dedra TCT 57 mm (5/8") universal hole saw is designed for cutting precise circular openings in a range of common building materials. The cutting rim is fitted with tungsten carbide tipped (TCT) teeth that provide improved wear resistance and help maintain cutting performance over repeated use. This 57 mm diameter hole saw is suitable for making openings for pipes, conduits and fittings and is compatible with standard arbor attachments for cordless and corded drills.

Advantages

The TCT teeth deliver higher durability than standard HSS blades and provide smoother cutting in abrasive and mixed materials. Its universal design allows cutting through wood, plywood, laminated boards and many non-ferrous metals while keeping the hole edge reasonably clean. The robust construction reduces tooth wear and maintains cutting geometry over many cuts, supporting consistent hole size and faster work progress.

Suitable for

• Cutting round openings for plumbing pipes and electrical conduit
• Making holes for door hardware and recessed fittings
• Drilling through wood, plywood, MDF and laminated panels
• Light cutting of non-ferrous metals such as aluminium and thin sheet metal

Key specifications

• Cutting diameter: 57 mm (5/8")
• Tooth type: Tungsten carbide tipped (TCT)
• Intended use: Universal / multi-material cutting
• Compatibility: Fits standard hole saw arbors for handheld drills
• Typical applications: Pipe and conduit openings, fittings, hardware installation

How to use

Fit the hole saw onto an appropriate arbor and secure it to the drill. Mark the centre point of the required hole, clamp the workpiece if possible, and start drilling at low speed to create a pilot guide. Increase speed moderately while applying steady, even pressure; avoid forcing the tool to prevent overheating or chipping of the carbide tips. For thicker or metallic materials, use cutting lubricant and periodically withdraw the cutter to clear chips and allow cooling. After cutting, deburr the hole edge as needed for a clean finish.

Usage recommendations

Use appropriate personal protective equipment, such as safety glasses and gloves, and secure the workpiece before drilling. Match drill speed and feed pressure to the material being cut—lower speeds and cutting fluid for metals, moderate speeds for wood and composites. Inspect the TCT teeth regularly and replace the cutter when wear affects cutting quality.
