Diamond core drill bit Norton Clipper VB Extreme 20 mm with M14 shank

The Norton Clipper VB Extreme 20 mm diamond core drill bit with M14 shank is designed for drilling precise small-diameter holes in hard construction materials. The bit features an industrial diamond cutting edge that provides efficient cutting and extends life when working with concrete, masonry, ceramic tiles and natural stone. The M14 threaded shank allows direct mounting to compatible rotary tools and angle grinders for controlled, high-speed drilling.

Advantages

The industrial diamond segment ensures consistent cutting performance and wear resistance during repetitive drilling tasks. A narrow 20 mm cutting diameter enables accurate hole placement and minimal material removal. The M14 shank design provides quick, secure attachment to machines that accept threaded accessories, reducing setup time. The bit is balanced for stable rotation and is suitable for wet and dry drilling depending on the application and tool used.

Suitable for

• Drilling holes in reinforced and non-reinforced concrete
• Creating openings in masonry and brickwork
• Cutting clean holes in ceramic and porcelain tiles
• Drilling small-diameter holes in natural and engineered stone

Key specifications

• Cutting diameter: 20 mm
• Shank type: M14 threaded
• Cutting edge: industrial diamond segments
• Intended use: concrete, masonry, tiles, stone
• Compatibility: rotary tools and angle grinders with M14 accessory thread

How to use

Secure the M14 shank into a compatible rotary tool or angle grinder according to the machine manufacturer’s instructions. Mark the drilling position and start at low speed to establish the hole. Apply steady, moderate pressure and increase speed as the diamond segments engage the material. For best cutting performance and extended tool life, periodically withdraw the bit to clear debris. When drilling tiled surfaces, use a backing support or tape to reduce chipping at the exit side.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, gloves and a dust mask. For hard or reinforced materials consider using water cooling to reduce heat and prolong segment life; ensure the chosen method is compatible with the power tool and site safety rules.
