Eveflex Rubber Knife Edge Burr, 508, Blue - Coarse, 2.5 X 14.5mm

Ideal for quick material removal and shaping Perfect for smoothing out imperfections on metal Mounted on a 2.34mm shank Maximum rotation speed of 20,000 RPM Ideal for narrow areas and inside edges Sold individually For use with a pendant drill, hobby drill or micromotor This blue Eveflex knife edge profile burr, mounted on a 2.34mm shank, is made from rubber material infused with a coarse grit abrasive compound. Used primarily for deburring, cleaning, and rough finishing on metal surfaces. It helps to remove excess material, smooth rough edges, and shape surfaces before finer finishing is done. The rubber composition allows for more controlled abrasion, reducing the risk of overcutting or damaging the jewelry piece while providing a more uniform finish compared to metal burrs. It`s often used for refining surfaces, removing oxidation, and prepping pieces for polishing. Used in conjunction with a pendant motor, micromotor or hobby drill. For the ideal finish, start with coarse grit and gradually work through to extra fine, finishing with a final luster polish to achieve a mirror-like shine. This knife edge profile blue Eveflex burr measures approximately 2.5mm thick x 14.5mm in diameter.https://www.cooksongold.com/Jewellery-Tools/Eveflex-Rubber-Knife-Edge-Burr,----508,-Blue---Coarse,-2.5-X-14.5mm-prcode-970-310?p=gs
