Hole saw Dedra DED1508-D for concrete, brick and stone, 120 mm diameter, 1 pc

Hole saw Dedra DED1508-D for concrete, brick and stone with a cutting diameter of 120 mm is a single-piece accessory designed for creating circular openings in masonry and natural stone. The tool is intended for use with compatible drills and rotary machines when fitting pipes, ventilation ducts or electrical conduits. Its construction is suited to abrasive materials but requires correct mounting and cooling during prolonged use.

Advantages

The Dedra DED1508-D hole saw is built for cutting through dense building materials such as concrete, brick and stone, providing a consistent 120 mm bore. As a single-piece unit it simplifies handling and storage. Its robust construction supports repeated use when installed on a suitable arbor and used with appropriate drilling equipment. When used with intermittent cutting and coolant or water, it helps maintain cutting efficiency and blade life.

Suitable for

• Creating circular openings for pipes in masonry walls
• Cutting holes for ventilation ducts in brick or concrete
• Drilling access points for electrical wiring through stone surfaces
• On-site construction and renovation projects requiring 120 mm diameter holes

Key specifications

• Cutting diameter: 120 mm
• Material compatibility: concrete, brick, natural stone
• Package quantity: 1 piece
• Designed for use with compatible drills and suitable arbors

How to use

Attach the hole saw to a compatible arbor and secure it to a drill or rotary machine according to the tool manufacturer’s instructions. Mark the center point of the opening, start drilling at low speed to establish the pilot, then apply steady pressure while maintaining a controlled rotational speed. For dense materials, use intermittent cutting and apply coolant or water to reduce heat and remove dust. Do not exceed the recommended speed for the arbor and drill, and stop periodically to clear debris and inspect the cutting edge.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask and hearing protection. Select a drill with sufficient power and a compatible arbor; ensure firm workpiece clamping. For best results in reinforced concrete or very hard stone, consider progressive drilling steps and frequent cooling to prolong the hole saw’s life.
