Diamond core drill bit Norton Clipper VB Extreme 45 mm M14 shank

The Norton Clipper VB Extreme diamond core drill bit with a 45 mm cutting diameter and M14 threaded shank is designed for producing precise circular holes in masonry, concrete, brick and similar building materials. Compatible with hand-held angle grinders and drill adapters that accept an M14 connection, this core bit is intended to deliver clean cuts and reliable performance in installation, plumbing, electrical and general construction tasks where a 45 mm hole is required.

Advantages

The diamond-segment cutting edge provides efficient material removal and sustained cutting performance on abrasive substrates. The M14 threaded shank ensures secure attachment to compatible angle grinders and adapters for stable operation. The product’s geometry and diamond composition are optimized to reduce vibration and promote straighter holes, while the 45 mm diameter covers common hole sizes for pipework and cabling installations.

Suitable for

• Drilling 45 mm holes in concrete and reinforced masonry for pipe and conduit passage
• Installing plumbing fixtures and mounting hardware in brick or block walls
• Creating openings for electrical wiring and cable grommets in building materials
• Use with hand-held angle grinders or drill adapters that accept an M14 shank

Key specifications

• Shank type: M14 threaded shank for direct fit to compatible angle grinders and adapters
• Cutting technology: diamond-segment tip for durable performance on masonry and concrete
• Intended materials: masonry, concrete, brick and similar abrasive building materials
• Typical applications: installation, plumbing, electrical and general construction hole cutting

How to use

Securely fit the Norton Clipper VB Extreme core bit into an angle grinder or adapter with an M14 thread, ensuring the tool is powered off and unplugged during mounting. Mark the hole center on the work surface and start drilling at low speed to establish the pilot contact, then increase speed and apply steady, moderate pressure. When drilling deep or in reinforced material, withdraw periodically to clear debris and, where applicable, use water cooling or reduced speed to limit heat build-up. After completing the hole, stop the tool before removing the bit from the workpiece.

Usage recommendations

Use appropriate personal protective equipment (eye, ear and dust protection) and follow the angle grinder manufacturer’s safety guidelines. For best results on reinforced concrete and dense masonry, combine controlled drilling speed with intermittent withdrawal to evacuate dust; consider a compatible dust extraction adapter when working indoors to maintain a clean and safe work environment.
