Diamond core drill bit Norton Clipper VB Extreme 8 mm with M14 thread

The Norton Clipper VB Extreme 8 mm diamond core drill bit with M14 thread is a compact cutting tool designed for precision core drilling in hard surfaces. It is intended for use with angle grinders or rotary tools that accept M14 accessories and provides a small-diameter diamond cutting crown for creating accurate through-holes and sampling cuts in tile, natural stone, ceramics and similar materials. The construction balances cutting speed and durability for short, controlled drilling operations where a narrow core is required.

Advantages

This diamond core drill bit combines a diamond-segment cutting crown with a robust metal body and an M14 threaded connection for secure mounting on compatible power tools. Its narrow 8 mm diameter allows for precise, minimal-damage perforations and sample extraction. The product is suitable for tasks where access is limited or where small, accurate holes are needed without the expense or complexity of larger core drilling systems.

Suitable for

• Drilling precise through-holes in ceramic and porcelain tiles
• Sampling and small cores in natural stone and engineered stone
• Installing small fixtures or conduit in tiled surfaces
• Creating pilot or guide holes for subsequent larger drilling operations

Key specifications

• Cutting diameter: 8 mm
• Connection type: M14 threaded mounting for angle grinders and rotary tools
• Cutting material: diamond segments bonded to metal matrix
• Intended materials: tile, ceramic, natural stone, engineered stone and similar hard surfaces
• Typical use: dry or controlled wet drilling in small diameters (use method depends on tool and material)

How to use

Fit the drill bit securely to an angle grinder or rotary tool with an M14 thread, following the tool manufacturer’s instructions for mounting and safety. Mark the drilling point, stabilize the workpiece, and start the tool at low speed to position the bit, then apply steady, moderate pressure and increase speed as appropriate for the material. For hard materials and prolonged cuts, use intermittent drilling or controlled wet cooling where compatible with the tool to reduce heat and prolong bit life. Observe all personal protective equipment requirements, including eye protection and dust control measures.

Usage recommendations

Use the Norton Clipper VB Extreme 8 mm diamond core drill bit for short, precise core and sampling tasks. Avoid excessive side load or high pressure; let the diamond segments do the cutting. For tiled surfaces, consider using a backing support or low-speed entry to prevent chipping. Maintain appropriate cooling and pause for cooling when performing multiple consecutive holes to extend tool life.
