Core Drill Bit for Concrete HOGERT HT6D478 — Diamond 82 mm

Diamond-tipped core bit for drilling holes in concrete, masonry and other hard materials. Designed for use in construction and renovation tasks where precise, clean circular holes are required. The diamond coating on the cutting edges produces even drilling results with minimal surface irregularities.

Advantages

The diamond-coated cutting edges deliver consistent cutting performance and long wear life compared with standard masonry bits. Its 82 mm diameter creates uniform, round holes suitable for pipes, conduits and anchor installations. The tool is engineered for use with standard rotary core drilling setups common on construction sites.

Suitable for

• Drilling 82 mm circular holes in concrete and masonry
• Creating openings for plumbing pipes and electrical conduits
• Installation of anchors, sleeves and through-holes in renovation works
• Professional construction and building maintenance tasks

When it may not be suitable

Not intended for use in very soft materials such as plasterboard or for cutting metal. Performance and lifespan will be reduced if used without appropriate drilling equipment, coolant/wet drilling where required, or when applied with excessive side load.

Key specifications

• Cutting diameter: 82 mm
• Tip: diamond-coated cutting edges
• Suitable materials: concrete, masonry and other hard mineral substrates
• Typical application: core drilling for installations and anchors

How to use

Mount the core bit securely to a compatible core drill or rotary drilling rig following the drill manufacturer’s instructions. For best results, use steady forward pressure and keep the bit aligned perpendicular to the work surface. Use water cooling or intermittent drilling as appropriate for the material to reduce heat and extend diamond life. Clear the hole of debris periodically to maintain cutting efficiency.

What to consider before purchase

• Verify that your drill/adapter fits the core bit connection type and supports an 82 mm bit.
• Confirm suitability for the material you plan to drill (concrete, masonry, etc.).
• Consider whether wet or dry drilling will be used and ensure your equipment supports the chosen method.

Usage recommendations

Use with a stable drilling rig, apply consistent axial pressure, and use water cooling when drilling dense concrete to maximise life and hole quality.
