Hole Saw DEDRA H1237 5.2 cm for Stone and Concrete

The Dedra H1237 hole saw with a 5.2 cm diameter is designed for drilling clean circular openings in stone and concrete. Constructed for durability, this hole saw provides consistent cutting performance for tasks that require precise round holes. It is suitable for use with compatible drill rigs and holders that accept standard arbor attachments and is intended for both professional tradespeople and home users working on masonry surfaces.

Advantages

The cutting edge is optimized for abrasive materials such as stone and concrete, offering reliable removal of material with minimal chipping when used correctly. The 5.2 cm cutting diameter allows for accurate, repeatable hole sizes for installations and penetrations. The tool's construction emphasizes long-term wear resistance and stable performance under typical drilling loads on masonry substrates.

Suitable for

• Drilling holes for pipes and conduits through stone or concrete walls
• Installing electrical boxes or fixtures in masonry
• Creating openings for anchors, sleeves, or ventilation ducts in concrete

Key specifications

• Cutting diameter: 5.2 cm
• Material compatibility: stone, concrete, masonry
• Design: circular hole saw for use with compatible drill arbors
• Typical application: wet or dry drilling depending on drill and material conditions

How to use

Select a suitable drill and arbor that match the hole saw's mounting system and ensure the tool is securely fastened. Mark the drilling position on the masonry surface and, if possible, start with a pilot guide or center punch to stabilize the cut. Operate the drill at the recommended speed for masonry cutting, apply steady pressure, and allow the tool to do the work—avoid forcing the saw to prevent excessive wear or damage. Use appropriate personal protective equipment including eye protection, gloves, and a dust mask. When cutting deep or dense concrete, consider intermittent breaks to clear debris and reduce heat buildup.

Usage recommendations

For best results on stone and concrete, use low to moderate drilling speeds, keep the cutting zone clear of debris, and consider water cooling when the equipment and jobsite conditions allow to extend the life of the hole saw and reduce dust.
