Hole Saw DEDRA H1235 for Stone and Concrete 3.2 cm

The DEDRA H1235 hole saw for stone and concrete with a 3.2 cm diameter is a purpose-built cutting tool for making precise circular openings in hard masonry materials. Designed for use with compatible drills and rotary tools, this hole saw delivers a clean cut in brick, concrete, tile, and natural stone when used with appropriate drilling technique and correct feed rate. Its size makes it suitable for small-diameter penetrations such as conduit entries, pipe leads and anchor sockets.

Advantages

Constructed for durability, the hole saw combines a hardened cutting edge with a solid body to resist wear when working with abrasive materials. The tool provides accurate hole dimensions and consistent performance, reducing the need for finishing work around the cut. Its compact diameter and geometry support controlled drilling and help maintain drill stability during operation.

Suitable for

• Drilling conduit and cable entries in masonry walls
• Creating openings for small-diameter pipes and anchors
• Installing fixtures where precise small holes in concrete or stone are required

Key specifications

• Material compatibility: stone, concrete, brick, tile, natural stone
• Cutting diameter: 3.2 cm
• Type: hole saw for masonry
• Intended mounting: compatible with rotary drills using appropriate arbor or adapter
• Performance: designed for clean, circular cuts in hard materials when used with correct speed and cooling

How to use

Mark the center point of the required hole and secure the workpiece if possible. Fit the hole saw to a suitable arbor and attach it to a drill that provides stable speed and torque; use a drill with hammer mode turned off unless the arbor or manufacturer specifies otherwise. Start drilling at low speed to establish a guide, then increase speed moderately and apply steady, even pressure. For thicker or very hard materials, withdraw periodically to clear debris and allow cooling. Finish the cut by reducing pressure as the hole completes to avoid chipping the exit edge.

Usage recommendations

Use water or periodic lubrication to reduce heat buildup when cutting dense stone or concrete. Wear appropriate personal protective equipment—safety glasses, dust mask and hearing protection—and secure the workpiece. Select a drill and arbor rated for masonry hole saws and match drilling speed to material hardness for best results.
