Hole Saw Dedra TCT 127 mm 5/8'' — bi-metal tooth circular cutter

Dedra TCT 127 mm 5/8'' — bi-metal tooth circular cutter is a hole saw designed to create 127 mm diameter openings with a 5/8'' arbor connection. The cutter features tungsten carbide tipped (TCT) teeth that improve edge durability and cutting performance when working with wood-based materials such as solid wood, MDF and laminated boards. The tool is intended for use with compatible drills and arbors to produce clean circular cutouts for pipe penetrations, vents and door hardware installation.

Advantages

The TCT teeth provide extended wear resistance compared with standard high-speed steel teeth, maintaining sharpness during repetitive cutting in abrasive wood-based panels. The 127 mm cutting diameter suits common installation requirements while the 5/8'' arbor compatibility ensures fitment with a wide range of power drills and drill arbors. The bi-metal construction balances cutting performance and flexibility for typical on-site and workshop tasks.

Suitable for

• Cutting circular openings in solid wood
• Creating holes in MDF and laminated boards
• Installing plumbing pipes and ventilation ducts
• Making door hardware and lockset cutouts
• General joinery and retrofit openings for fixtures

Key specifications

• Cutting diameter: 127 mm
• Arbor connection: 5/8'' (compatible with 5/8-inch arbors)
• Tooth type: Tungsten carbide tipped (TCT)
• Material suitability: Wood, MDF, laminated boards and similar wood-based materials
• Construction: Bi-metal tooth circular cutter

How to use

Fit the hole saw to a compatible arbor with a 5/8'' shank and secure it to a drill designed for hole saw use. Mark the centre point of the required opening, start drilling at low speed to establish a pilot location, then increase speed as appropriate for the material. Apply steady, even pressure and allow the TCT teeth to cut without forcing; clear chips periodically to avoid clogging. After cutting, withdraw the hole saw and remove the cut-out plug. Inspect the teeth and clean any residue before subsequent use.

Usage recommendations

Use appropriate personal protective equipment (eye protection, gloves and dust mask) and clamp workpieces securely. For best results in laminated or veneered boards, consider scoring the surface with a fine blade or backing the material to reduce tear-out. Do not use the hole saw on metal, masonry or fiberglass unless explicitly tested for those materials.
