Hole Saw Dedra 25 mm TCT 1/2" for drilling with compatible arbors

Dedra 25 mm TCT hole saw with a 1/2" connection is a round cutting tool engineered for creating precise circular openings in materials suitable for tungsten carbide-tipped (TCT) tooling. Designed to work with drills and compatible arbors that accept a 1/2" shank, this hole saw provides a compact diameter for installations where small, accurate cutouts are required, such as routing pipes, cables or mounting fixtures.

Advantages

The TCT (tungsten carbide-tipped) cutting edge maintains sharpness and resists wear when cutting abrasive or mixed materials. A 25 mm diameter offers precise, repeatable hole size for small-diameter penetrations. The standard 1/2" connection ensures compatibility with most drill chucks and arbors, simplifying tool changes and reducing setup time. The cylindrical form and tooth geometry provide consistent cutting performance and clean circular edges when used with appropriate pilot bits and arbor support.

Suitable for

• Cutting small circular holes for pipe and conduit installations
• Creating openings for cable routing and cable glands
• Drilling precise mounting holes for fixtures, fittings and hardware
• Use in hand-held drills and drill presses with compatible 1/2" arbors

Key specifications

• Cutting diameter: 25 mm
• Cutting material: tungsten carbide-tipped teeth (TCT)
• Connection type: 1/2" shank compatible with standard arbors and chucks
• Intended use: cutting round holes in materials compatible with TCT tooling

How to use

Mount the hole saw onto a compatible arbor and secure the 1/2" shank in the drill chuck or arbor holder. Use an appropriate pilot bit to center the tool before engaging the cutting teeth. Start drilling at low speed to establish the cut, then increase speed and apply steady, moderate pressure to allow the TCT teeth to cut efficiently. Withdraw periodically to clear chips and prevent heat buildup. After cutting, remove the slug from the hole saw and inspect the edge for burrs; deburr if necessary.

Usage recommendations

Use suitable personal protective equipment (safety glasses, gloves) and select drill speed according to the work material. For metal or abrasive materials, use cutting fluid or cooling as recommended for TCT tools. Ensure the arbor and pilot bit are rated for the material being cut and avoid excessive side loads to prolong tool life.
