Diamond Router Bit EXO EXO PRO rounded edge cylinder 5.0 mm

Diamond router bit EXO EXO PRO rounded edge cylinder 5.0 mm is a diamond-coated cutting tool designed for precise edging, profiling and finishing of hard materials such as natural stone, engineered stone, ceramics and concrete. The cylinder shape with a rounded edge delivers consistent radiused profiles and smooth transitions, making it suitable for chamfering, surface smoothing and detailed edge work. The 5.0 mm cutting diameter provides a narrow, controlled cut for fine profile work and finishing passes on both handheld routers and CNC machines when shank size and recommended RPM are compatible.

Advantages

The diamond coating ensures long tool life and stable cutting performance on abrasive materials. The rounded edge geometry reduces the risk of chipping on brittle substrates and produces a uniform radius without additional sanding. The cylinder body offers accurate straight-line guidance and predictable material removal, enabling repeatable results across multiple pieces. Designed to work reliably in wet and dry routing applications when appropriate cooling and dust control are used.

Suitable for

• Edging, rounding and profiling of natural and engineered stone
• Finishing ceramic tiles and porcelain edges
• Smoothing and chamfering concrete edges and architectural elements
• Detail work on countertops, sills and stair treads

Key specifications

• Cutting diameter: 5.0 mm
• Tool shape: cylinder with rounded edge (radius profile)
• Abrasive: diamond-coated cutting surface
• Intended materials: natural stone, engineered stone, ceramics, concrete and similar hard materials
• Compatible use: handheld routers and CNC machines (subject to matching shank and speed)

How to use

Secure the bit in the router collet ensuring the shank is fully seated and tightened according to the router manufacturer's specifications. Begin routing at a moderate feed rate and appropriate spindle speed for the material; increase speed or reduce feed if the bit shows signs of clogging or poor finish. For brittle materials, use multiple light passes rather than a single heavy cut to avoid chipping. When possible, use water coolant or mist to reduce heat and prolong diamond life, and always follow safety practices including eye, ear and respiratory protection.

Usage recommendations

Match the router speed and feed to the material hardness, perform test cuts on sample material to set final parameters, and consider wet routing for extended tool life and improved finish. Avoid excessive lateral force and allow the diamond surface to do the cutting.
