## Summary description

Dedra TCT hole saw, 28 mm diameter with 1/2" arbor, designed for cutting circular holes in materials such as wood and thin metals. Constructed with TCT (tungsten carbide tipped) teeth for improved wear resistance and durability. Suitable for hand-held drills and impact drivers with 1/2" chucks; used for plumbing, electrical installations, and general construction tasks requiring precise round openings.

## Long description

Dedra TCT hole saw, 28 mm diameter with a 1/2" arbor, is a cutting tool engineered for creating precise circular openings in wood and thin metal sheets. The tool features tungsten carbide tipped (TCT) teeth that offer improved wear resistance and longer cutting life compared with standard bi-metal or high-speed steel teeth. It is compatible with hand-held drills and impact drivers that accept a 1/2" arbor, and is intended for tasks that require accurate, repeatable round holes such as pipe penetrations, cable entries and fixture installations.
Advantages
The TCT tooth construction provides enhanced durability and consistent cutting performance when working with wood and thin metals. A 28 mm cutting diameter delivers a compact, precise hole size for common plumbing and electrical applications. The 1/2" arbor ensures secure mounting in most standard drill chucks and impact drivers, reducing wobble and improving safety during operation. The design balances cutting speed and edge life to reduce downtime for frequent use.
Suitable for
 Cutting circular holes in soft and hardwoods
 Creating openings in thin sheet metal and aluminium
 Drilling holes for plumbing pipes and cable glands
 Installing fixtures, sockets, and switches in construction and renovation
Key specifications
 Cutting diameter: 28 mm
 Arbor type: 1/2" shank, compatible with standard drill chucks
 Tooth material: Tungsten carbide tipped (TCT)
 Primary materials: Suitable for wood and thin metals
 Intended use: Hand-held drills and impact drivers
How to use
Secure the 1/2" arbor firmly in the drill chuck and confirm concentricity before cutting. Mark the center of the desired hole on the workpiece and, if possible, clamp the material to prevent movement. Start drilling at low speed to establish the pilot and then increase speed to an appropriate rate for the material being cut. Apply steady, even pressure—avoid excessive force that can overheat the cutting teeth. For metal applications, use cutting lubricant and periodically clear swarf to maintain cutting efficiency. After completing the cut, withdraw the hole saw carefully and clean the teeth and arbor.
Usage recommendations
Use appropriate personal protective equipment, including eye protection and gloves. Match drill speed and feed pressure to the material: lower speeds for metals and higher speeds for most wood types. When cutting metal, apply cutting fluid and allow intermittent cooling to preserve the carbide tips. Inspect the teeth regularly and replace the hole saw if teeth are chipped or worn to maintain cut quality and safety.
