Diamond core drill bit Norton Clipper VB Extreme 12 mm with M14 thread

The Norton Clipper VB Extreme 12 mm diamond core drill bit with M14 thread is a compact cutting tool intended for creating small, precise holes in hard surfaces. It is manufactured for use with handheld rotary and angle drills that accept M14-mounted accessories and is suitable for tasks such as tile fitting, plumbing penetrations, electrical outlet openings and light repair work. The 12 mm diameter and diamond-segment cutting edge provide controlled drilling in abrasive and brittle materials while the M14 threaded connection ensures secure mounting to compatible chucks and adapters.

Advantages

The diamond cutting segments deliver efficient material removal and prolonged life when used on ceramic, porcelain, natural stone and concrete. Its small diameter offers high positional accuracy for installation tasks that require neat, narrow holes. The M14 thread is a common industrial mounting standard that provides reliable fixation in handheld drills and angle grinders equipped for core drilling. Overall design balances cutting performance with manageable torque and stable operation in demanding substrates.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Creating small openings in natural stone and engineered stone
• Punching through concrete, cement and mortar for anchors or pipes
• Installation work involving plumbing, electrical boxes and fixtures
• Repair and refurbishment tasks where narrow, precise holes are required

Key specifications

• Cutting diameter: 12 mm
• Threaded connection: M14 for mounting to compatible drills and adapters
• Cutting material: diamond segments suitable for abrasive and brittle substrates
• Intended use: dry and light wet drilling in tile, ceramic, stone and concrete
• Tool compatibility: handheld rotary and angle drills that accept M14-mounted accessories

How to use

Select an appropriate drill or adapter that accepts M14-threaded accessories and secure the core bit firmly. Mark the drilling position and, where possible, start at low speed to establish the hole before increasing rotation. Apply moderate, steady pressure and avoid excessive side loads that could damage the diamond segments or the workpiece. For tiled surfaces, use a backing support or masking to reduce chipping. If recommended by the drill manufacturer, use intermittent water cooling or light wetting to extend segment life and reduce dust; otherwise follow dry-drilling guidance for the material.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask and gloves. Match drill speed and feed pressure to the material: lower speeds for hard ceramics and stone, moderate speeds for concrete. Inspect the bit regularly for wear; replace when diamond segments are significantly worn or cutting efficiency is reduced. Ensure the drill and mounting are rated for core bit use and follow the tool manufacturer's safety instructions.
