Diamond Hole Saw Högert Technik HT6D478 — 82 mm Turbo Segment

Diamond Hole Saw Högert Technik HT6D478 — 82 mm Turbo Segment is a diamond-cutting hole saw designed for creating clean, precise holes in hard building materials. With an 82 mm cutting diameter and turbo segment rim, this diamond hole saw delivers faster cutting speed and improved debris evacuation compared with standard rims. It is intended for use with angle grinders and drill rigs when an appropriate arbor or adapter is fitted, and is suitable for tiling, plumbing and general construction tasks that require accurate circular openings in ceramic, porcelain, natural stone and concrete.

Advantages

The turbo segment design combines diamond cutting edges with an open rim geometry to accelerate material removal and reduce clogging during drilling. The 82 mm diameter offers a commonly used size for pipe penetrations and fixture installations. Constructed for use on hard, abrasive substrates, the hole saw provides consistent hole quality and a reduced need for finishing. It is compatible with standard power tools when paired with a matching arbor, enabling efficient installation workflows.

Suitable for

• Cutting holes for plumbing pipes through ceramic and porcelain tiles
• Creating openings for electrical boxes and conduit in masonry
• Installing fixtures through natural stone and engineered stone surfaces
• Making circular penetrations in concrete and cement-based materials

Key specifications

• Cutting diameter: 82 mm
• Segment type: turbo diamond rim for faster cutting and improved debris removal
• Suitable materials: ceramic, porcelain, natural stone, engineered stone, concrete
• Recommended tool compatibility: angle grinders and drill rigs with appropriate arbor/adapter
• Intended use: wet or dry drilling depending on material and tool, observe tool limits

How to use

Fix the hole saw securely to a compatible arbor or adapter designed for your angle grinder or drill rig. Mark the center point of the hole on the workpiece and start drilling at low speed to establish a guide groove; progressively increase speed while maintaining steady, even pressure. For ceramic, porcelain and natural stone, use light feed pressure and, if possible, intermittent water cooling to reduce dust and extend tool life. For concrete and harder substrates, operate at the recommended speed for the tool and backing equipment, and let the diamond segments perform the cutting without excessive force.

Usage recommendations

Use protective eyewear, dust mask and hearing protection when operating power tools. Select an appropriate arbor for secure mounting and match rotational speed limits of the hole saw to your tool. For best results on tiles and stone, start drilling on the glazed side and consider a sacrificial backing to avoid chipping. Follow the power tool manufacturer's guidelines for wet or dry operation to ensure safety and maximize cutting performance.
