ÜLKA Carbide Corn Nail Drill Bit 5 × 13 mm (Blue, Medium Cut) С513-M

The ÜLKA professional corn-shaped tungsten carbide nail drill bit (5.0 mm diameter, 13.0 mm head length) with a blue indicator band is a heavy-duty, premium tool engineered from ultra-dense tungsten carbide (HRA 95%). Featuring a medium cross-cut fluting pattern, this bit is perfectly balanced for rapid, comfortable, and safe removal of artificial enhancements without vibration or painful heat buildup.

Primary Uses and Application:

• Fast and efficient bulk removal of artificial coatings (gel polish, hard gel, acrylgel, polygel, and acrylic).

• Length reduction and shaping during nail extension or maintenance procedures.

• Thinning out enhancement thickness and clearing out natural outgrowth from underneath the free edge.

• Treatment of hyperkeratosis, calluses, and thickened nails in pedicure procedures.

• Streamlined debulking of dense, thick product layers with maximum control.

Proper Maintenance, Cleaning, and Sterilization:

While tungsten carbide bits possess exceptional wear resistance, they require a strict sanitation protocol to maintain the sharpness of their blades:

1. Disinfection:

   Immediately after use, submerge the drill bit into a professional disinfectant solution. Use only top-tier concentrates formulated with corrosion inhibitors specifically designed for metal rotary tools.

2. Ultrasonic Cleaning:

   To thoroughly flush out product debris trapped within the deep cross-cut flutes, utilize the ÜLKA Pulse ultrasonic cleaner. Afterward, guarantee that the bits are completely dry. To accelerate drying, use the 80°C drying cycle for 30 minutes in the Jupiter 10V dry heat sterilizer.

3. Thermal Sterilization:

   Place completely dry bits into self-sealing sterilization pouches (kraft bags) and sterilize them inside the professional ÜLKA Mercury 2V or Jupiter 10V dry heat sterilizers at a temperature of 160–180°C.

Important Guidelines:

• Store nail drill bits exclusively in dry bur stands or storage cases that shield them from ambient moisture, dust, and environmental contaminants.

• Do not drop or bump carbide drill bits against hard surfaces. Despite its extreme hardness, tungsten carbide is brittle. Dropping it onto salon tiles can chip the blades, bend the shank, or throw off its rotational center, creating severe wobbling that will damage micromotor handpiece bearings.
