Hole Cutter for Styrofoam and Wool Drel 68 mm CON-AOR-0168

The Drel 68 mm Hole Cutter CON-AOR-0168 is designed for creating clean, round openings in styrofoam (EPS) and mineral wool insulation. Sized for 68 mm diameters, this cutter attaches to compatible drills or rotary tools and produces consistent holes for pipe passages, ventilation ducts, cable glands, or mounting fixtures during insulation installation and renovation. The simple construction focuses on a circular cutting edge matched to the specified diameter to ensure repeatable, accurate results in soft and fibrous insulation materials.

Advantages

This hole cutter provides uniform 68 mm openings with minimal tearing or compression of EPS or mineral wool. Its dedicated circumference reduces the need for manual finishing and helps maintain the insulating material’s integrity. The tool is compact and lightweight, allowing for easy handling and fast work progress when preparing multiple penetrations. Compatibility with common drills and rotary tools ensures straightforward attachment and operation on-site.

Suitable for

• Cutting circular openings in EPS (styrofoam) insulation
• Making holes in mineral wool and similar fibrous insulation
• Preparing penetrations for pipes, vents, and cable entries
• Use during renovation, HVAC installation, and thermal insulation work

Key specifications

• Cutter diameter: 68 mm
• Material suitability: expanded polystyrene (EPS) and mineral wool
• Attachment: compatible with standard drills and rotary tools
• Cut type: circular through-cut for insulation panels and batt
• Application: on-site insulation penetration cutting for pipes and ducts

How to use

Secure the hole cutter to a compatible drill or rotary tool according to the tool manufacturer’s instructions. Mark the center of the desired opening on the insulation surface, align the cutter, and operate the drill at a moderate speed to let the cutter penetrate the material cleanly. Apply steady, even pressure without forcing the tool; allow the cutter’s edge to do the work. After cutting, remove any loose fibers or debris from the hole and verify fit for the intended pipe or fitting.

Usage recommendations

Wear appropriate personal protective equipment such as gloves, eye protection, and a dust mask when cutting mineral wool or EPS to avoid irritation and inhalation of particles. Use moderate drill speeds to prevent melting of EPS and to minimize dust generation. Keep the cutter clean and free of compacted debris to maintain cutting performance and accurate hole sizes.
