Core drill bit GRAPHITE 65 mm with SDS-plus adapter and centering pilot – concrete

Diamond-tipped core drill bit GRAPHITE 65 mm with SDS-plus adapter and centering pilot is designed for drilling precise circular openings in concrete. The 65 mm diameter bit uses a diamond cutting edge to cut through reinforced and non-reinforced concrete, producing clean holes for installation of pipes, conduits and anchor fixtures. Supplied with an SDS-plus adapter, the bit fits most SDS-plus rotary hammers and hammer drills, and the centering pilot drill improves start accuracy and reduces walking during drilling.

Advantages

The diamond tip provides improved cutting performance and longer life compared with standard carbide bits when used on concrete. Inclusion of an SDS-plus adapter allows quick fitting to compatible rotary hammers without additional chucks, while the centering pilot ensures stable starts and more accurate hole placement. The 65 mm diameter is a common size for through-holes for medium-diameter pipes and installations, delivering consistent circular cuts and reduced breakout around the hole edge.

Suitable for

• Drilling 65 mm diameter holes in reinforced and non-reinforced concrete
• Creating openings for plumbing pipes and electrical conduits
• Preparing anchor and fixation points in masonry
• Use with SDS-plus rotary hammers and hammer drills

When it may not be suitable

This core drill bit is optimized for concrete and similar masonry materials; it is not intended for extended use on hard natural stones or metals where diamond grit and bonding may wear differently. For precision countersinking, very shallow holes or working in very soft materials, a different bit type may deliver better results.

Key specifications

• Cutting diameter: 65 mm
• Tip type: diamond-tipped cutting edge
• Shank/adapter type: SDS-plus adapter included
• Includes: centering pilot drill for accurate starts
• Intended material: concrete and masonry

How to use

Mount the SDS-plus adapter into the rotary hammer or hammer drill according to the tool manufacturer’s instructions, then attach the core bit. Install the centering pilot in the bit if provided to locate the drilling position precisely. Start drilling at low speed to allow the pilot to establish the hole, then apply steady pressure and use hammer action if available for faster progression through concrete. Periodically withdraw the bit to remove debris and, where applicable, use water cooling or dust extraction to reduce dust and prolong bit life. After reaching the required depth, reverse the bit or carefully extract it to avoid chipping the hole edge.

What to consider before purchase

• Confirm compatibility of the SDS-plus shank with your rotary hammer or drill model
• Verify that 65 mm diameter is suitable for the pipes, conduits or anchors you plan to install
• Check whether water-cooling or dust extraction is required for your work environment

Usage recommendations

Use steady axial pressure and allow the diamond tip to cut without excessive force; keep the bit cool and clear of debris for longer life, and use appropriate personal protective equipment and dust control measures when drilling concrete.
