The ÜLKA green spike carbide burr (ref. C513-C) is a highly specialized professional tool, designed for nail experts, nail prosthetists, nail artists, and also for those passionate about home manicure. With a 5mm head and an active area of 13mm, this burr combines precision, efficiency, and safety for all your meticulous work on natural or artificial nails.
Fully made of high-quality tungsten carbide, the burr ensures excellent resistance to wear, heat, and minor impacts. The green spike profile means a finer cut and a less abrasive grain compared to the red spike, which reduces the risk of trauma to the nail plate. The 5mm head allows reaching sensitive areas like the cuticles or the sides of the nail, while the 13mm active part gives you room to work on the length or in the corners, with good control.
Before any intervention, thoroughly disinfect the burr using a suitable disinfectant. Mount it on your electric file or drill according to the model specifications. For optimal use, employ a moderate speed, between 10,000 and 18,000 rpm, depending on the material (gel, acrylic, natural nail) to avoid overheating and protect the carbide. Work with light and controlled movements, without pressing hard, keeping the burr in constant motion. Regularly clean the residues to prevent accumulation that could alter precision or damage the tool. After use, proceed with sterilization according to your protocol (autoclave or equivalent), complete drying, then store in a safe case to avoid impacts or corrosion.
Because you are looking for a professional, subtle finish without compromising on care and comfort. This burr is ideal when you want to avoid visible marks, regardless of the material you are working on. The green spike provides you with cutting finesse, while maintaining the strength and robustness of carbide. Perfect if you perform frequent poses, but also if you want to preserve the natural nail of your clients.
This version is recommended for nail prosthetists who perform precise finishes; for nail artists very attentive to the health of the natural nail; but also for knowledgeable individuals who seek a clean and delicate result. Use it especially for: refining the free edge, precisely removing residual glue, preparing the surface before applying polish or resin, or even removing semi-permanent polish without damaging the surface.
