Product Overview
Upgrade your workshop with the Pontas 10Pcs Carbide Rotary Drill Bit Set – a premium selection of high-hardness rotary files designed for efficient cutting, grinding, carving, and finishing. Featuring a 3mm (1/8") shank, 6mm double-cut heads, and 10 different head shapes, this kit delivers exceptional performance on metals, wood, plastics, and more. Whether you’re a professional metalworker, a DIY enthusiast, or a wood carving artist, these durable, long-life carbide burrs will become your go-to rotary tool accessories.

Key Features
🔹 Premium Carbide Construction
Made from high-grade solid carbide, offering outstanding hardness, wear resistance, and heat tolerance. Stays sharp longer than HSS or steel bits – ideal for heavy-duty applications.

🔹 Double Cut Design for Maximum Efficiency
Each head features a double-cut (cross-cut) tooth pattern that provides faster material removal, smoother surface finish, and reduced vibration. Perfect for controlled shaping and deburring.

🔹 10 Universal Head Shapes
From ball-nose and tree shapes to flame, cone, and cylindrical profiles – this set covers all common rotary file geometries. Tackle slotting, contouring, edge beveling, hollowing, and intricate detail work with ease.

🔹 Standard 3mm / 1/8" Shank
Compatible with most rotary tools, die grinders, and micro motors (e.g., Dremel, Proxxon, generic multi-tools). Quick and secure bit changes.

🔹 Compact & Versatile Size
Head diameter: 6mm / 0.24"

Head lengths (vary by shape): 7mm, 9mm, 12mm, 14mm, 15mm

Overall tool length (approx.): 35mm / 1.38"

Shank diameter: 3mm / 1/8"

Applications
✔ Metalworking & Fabrication – Weld cleaning, deburring, surface preparation, porting, and die finishing.
✔ Wood Carving & Sculpting – Shaping, hollowing, fine detailing, and smoothing.
✔ DIY & Modeling – Plastic trimming, engraving, circuit board work, and model making.
✔ Tool & Knife Making – Sharpening, contour grinding, and edge cleanup.

Why Choose Pontas Carbide Rotary Bits?
Sharp & Durable – Engineered for long life even under continuous use.

Precision Cutting – Double cut geometry ensures controlled material removal and a fine finish.

Heat-resistant – Carbide maintains hardness at high speeds (recommended RPM: 10,000–35,000).

Cost-effective – 10 essential shapes in one set, saving you from buying individually.

Usage Tips
Use with rotary tools or die grinders at 15,000–30,000 RPM for metal, lower speeds for wood/plastic.

Apply light pressure – let the carbide teeth do the work.

For metal work, use cutting fluid or wax to reduce heat and extend tool life.

Always wear eye protection and a dust mask.
