Diamond core drill bit Norton Clipper VB Extreme 35 mm with M14 shank

The Norton Clipper VB Extreme 35 mm diamond core drill bit with M14 shank is designed for creating precise circular holes in hard materials such as concrete, masonry and natural stone. It is intended for use with handheld rotary or angle drills that accept M14-mounted core bits and provides a reliable cutting edge for plumbing, electrical installations, sample extraction and other trade tasks requiring clean, accurate holes.

Advantages

This diamond core drill bit offers a durable diamond cutting segment for extended life when drilling abrasive substrates. The 35 mm diameter provides a commonly required size for pipe penetrations and fixture fittings while the M14 threaded shank ensures secure attachment to compatible rotary and angle drills. The design balances cutting speed and hole quality to reduce chipping and improve roundness of the drilled hole.

Suitable for

• Drilling through concrete for plumbing and heating pipework
• Creating openings for electrical conduit and cable runs
• Extracting small core samples for on-site testing
• Installing anchors, fixtures and fasteners in masonry

Key specifications

• Diameter: 35 mm
• Shank type: M14 threaded shank for direct mounting to compatible drills
• Cutting material: diamond segment suitable for hard, abrasive materials
• Intended materials: concrete, masonry and natural stone

How to use

Securely fit the M14 shank into a compatible handheld rotary or angle drill and ensure the connection is tight before operation. Mark the drilling location, begin at low speed to establish the pilot contact, then apply steady pressure and increase speed as appropriate for the material. Use a controlled feed rate to avoid overheating; for improved performance and segment life, periodically withdraw the bit to clear debris. When drilling reinforced concrete, maintain caution around rebar to avoid excessive wear or damage to the diamond segment.

Usage recommendations

Use water cooling or intermittent drilling with clearing pauses when possible to reduce heat and extend tool life. Wear appropriate personal protective equipment including eye protection, dust mask and hearing protection. Match drill speed and feed to the material hardness and keep the tool stable to achieve a clean, accurate hole.
