These are high-speed Friction Grip (FG) diamond burs consisting of a precision-engineered stainless steel shank and a working head coated with high-quality natural diamond grit. The EX 18 is used for standard material reduction, while the EX 18 F (Fine) is utilized for finishing and smoothing prepared tooth surfaces to ensure optimal restoration fit.

Features
Specialized Geometry: Designed with a specific taper and length to provide excellent access to interproximal areas and for refining shoulder or chamfer margins.
Grit Variations:
EX 18 (Standard): Features a medium grit (often blue-coded) for efficient initial reduction of enamel and dentin.
EX 18 F (Fine): Features a fine grit (red-coded, as seen in the image) for creating a smooth surface finish and perfecting the restoration margin.
High Concentricity: Manufactured to strict tolerances to ensure vibration-free rotation, which protects the high-speed handpiece turbine and improves clinical precision.
Superior Durability: The diamond particles are bonded using a high-tech electroplating process, ensuring the grit remains sharp and attached to the shank throughout multiple clinical procedures.
Efficient Debris Removal: The spacing of the diamond grit allows for the effective flushing of debris when used with water spray, preventing clogging and heat buildup.
