Hole saw Dedra TCT 121 mm (4.76") 5/8" arbor, universal cutting blade

Dedra TCT hole saw 121 mm (4.76") with a 5/8" arbor connection is a universal cutting blade designed for making clean, large-diameter holes in wood, laminated boards and select non-ferrous materials. The tungsten carbide-tipped (TCT) cutting edge combines wear resistance with cutting precision, while compatibility with standard drill/arbor assemblies and a drilled pilot bit requirement ensures accurate center positioning and stable cutting performance.

Advantages

The TCT cutting teeth provide increased durability and maintain sharpness longer than high-speed steel teeth when working with abrasive surfaces. The 121 mm diameter enables larger openings for installations and fixtures, and the 5/8" arbor connection fits common drill setups for straightforward mounting. The universal blade profile allows cutting across different sheet and board materials with consistent results and reduced risk of chipping on laminated surfaces.

Suitable for

• Cutting circular openings in solid wood and soft hardwoods
• Creating holes in laminated boards and furniture panels
• Drilling passage holes for pipes, cables and fixtures in carpentry and installation work
• Working with some non-ferrous materials such as soft aluminum sheets and plastics (depending on thickness)

Key specifications

• Cutting diameter: 121 mm (4.76")
• Arbor connection size: 5/8"
• Cutting edge: tungsten carbide-tipped (TCT)
• Material compatibility: wood, laminated board, selected non-ferrous materials
• Mounting: designed for use with drilled pilot bits and standard drill/arbor assemblies

How to use

Securely fit the hole saw to a compatible 5/8" arbor and install an appropriate pilot bit to ensure accurate centering. Mark the drilling position on the workpiece, clamp the material to prevent movement, and set the drill to a controlled speed appropriate for the material being cut. Begin drilling with light pressure to establish the pilot hole, then apply steady, even pressure while maintaining alignment. Periodically withdraw the hole saw to clear chips and reduce heat build-up; for laminated or delicate surfaces, use a backing support to reduce tear-out.

Usage recommendations

Use cutting lubricant or compressed air sparingly when working with non-ferrous metals to extend blade life and improve chip evacuation. Avoid excessive feed pressure and high rotational speeds to reduce wear on the TCT teeth and to maintain hole quality.
