## Long description

Diamond conical router bit Silver with M14 thread, diameter range 20–48 mm, is designed for shaping, chamfering and enlarging holes in hard materials such as natural stone, concrete and similar masonry. The conical profile and graded diamond cutting surface enable progressive material removal and controlled enlargement of openings. The tool is compatible with angle grinders and rotary tools featuring an M14 connection and is intended for both professional and DIY masonry tasks where reliable diamond abrasion is required.
Advantages
The diamond-coated conical shape provides consistent cutting performance across the entire 20–48 mm diameter range, while the M14 threaded shank ensures secure attachment to standard angle grinders and compatible rotary tools. Durable diamond abrasive segments resist wear when working on abrasive materials like concrete and natural stone, and the conical design allows smooth transition between diameters for precise chamfering and hole widening.
Suitable for
 Shaping and chamfering edges in natural stone and engineered stone
 Enlarging or deburring holes in concrete and masonry
 Preparing openings for anchors, pipes or fixtures in stone and concrete
 Repair and renovation work involving hard masonry materials
Key specifications
 Thread: M14 compatible shank for angle grinders and rotary tools
 Diameter range: 20–48 mm (conical profile)
 Cutting surface: diamond-coated conical segments for hard materials
 Primary materials: natural stone, concrete, masonry and similar substrates
 Typical applications: shaping, chamfering, hole enlargement and deburring
How to use
Install the diamond conical router bit onto an angle grinder or rotary tool with an M14 threaded connection, ensuring the tool is powered off and disconnected from mains before fitting. Secure the bit firmly according to the machine manufacturer's instructions. Operate the grinder at the recommended speed for diamond tooling and apply steady, controlled pressure while moving the conical bit progressively through the material to achieve the desired diameter or chamfer. Use cooling measures or intermittent cutting where appropriate to reduce heat buildup and prolong abrasive life. After use, inspect the cutting surface for wear or damage and replace the bit when performance declines.
Usage recommendations
Wear appropriate personal protective equipment including eye protection, respiratory protection and gloves. Use dust extraction or wet cutting where possible to minimise silica dust when working with concrete and natural stone. Match tool speed and feed rate to the hardness of the material and avoid excessive side pressure to maintain diamond segment life and achieve uniform cutting results.
