Diamond Hole Saw högert technik HT6D476 68 mm, turbo segment

The högert technik Diamond Hole Saw HT6D476 with a 68 mm cutting diameter is designed for drilling precise circular openings in hard building materials. The tool features a diamond cutting edge and a turbo-segment rim that improves cutting speed and debris evacuation. It is intended for use with compatible arbors on corded and cordless drills when working with ceramics, porcelain, natural stone and concrete.

Advantages

The turbo segment design combines aggressive cutting action with enhanced chip removal, reducing the risk of binding and overheating. The diamond edge ensures clean, accurate holes with minimal chipping on fragile surfaces like glazed tiles and porcelain. Compatibility with standard arbors allows quick fitting to most drill types, while the segmented rim helps maintain cutting performance over multiple uses.

Suitable for

• Drilling holes for plumbing and electrical fittings in ceramic and porcelain tiles
• Creating openings in natural stone and engineered stone countertops
• Cutting access holes in concrete and masonry for anchors or conduits
• Installing fixtures that require precise circular cuts in hard surfaces

Key specifications

• Cutting diameter: 68 mm
• Cutting edge: diamond grit
• Rim type: turbo segmented for improved debris removal
• Intended materials: ceramic, porcelain, natural stone, concrete
• Drive compatibility: for use with drills via compatible arbor (arbor not included)

How to use

Attach the hole saw to a compatible arbor and secure it in the drill chuck. Mark the centre of the hole on the workpiece and start drilling at low speed to establish the pilot position, applying steady light pressure. Increase speed gradually while keeping the tool aligned perpendicular to the surface. Use intermittent drilling and withdraw periodically to clear debris and prevent overheating. For brittle materials such as glazed tiles or porcelain, consider backing the workpiece to reduce chipping. Keep the work area stable and follow drill manufacturer safety instructions.

Usage recommendations

Use cooling or periodic water flushing when cutting hard stone or concrete to extend diamond life and reduce dust. Operate at moderate drill speeds and avoid excessive pressure; let the diamond grit perform the cutting. Replace the arbor washers and fastenings if worn to maintain concentric cutting and accuracy.
