🛠️ Dome-End (Ball) Carbide Burrs – For Hollow Recesses & Corner Chamfering

Right Lines Dome-End Carbide Burrs, also known as ball burrs, are specifically shaped for grinding and finishing round hollows, internal recesses, and undercuts. Their rounded profile allows access behind overhanging edges, making them perfect for weld chamfering, shaping, and intricate contour work.

Made from premium-grade tungsten carbide, these burrs deliver exceptional cutting power and durability on hard metals, and they’re also suitable for use on wood and plastics. Most options come with a 6mm spindle for die-grinders and drills, with 3mm spindles available for Dremel-style craft tools.

✅ Key Features:

• Rounded dome-end design – ideal for hollows, undercuts, and tight curves

• Excellent for corner weld chamfering, finishing and shaping

• High-grade tungsten carbide – long-lasting and wear-resistant

• Double-cut flutes for hard/ferrous metals

• Single-flute option available for non-ferrous materials

• Choose from 3mm or 6mm spindle sizes

• Extended spindle option available for hard-to-reach areas (on 9.5mm burrs)

• Also suitable for woodworking, resin shaping, and composite materials

📐 Specifications:

• Material: Tungsten carbide

• Head Shape: Dome / Ball End

• Cut Type:

  • Double Flute (Hard Metals) – Steel, stainless, cast iron

💡 Pro Tip:

For aluminium and other soft metals, choose the non-ferrous grade to prevent clogging and heat buildup. Use gentle pressure and maintain high rotational speed for optimal control and finish.

🔧 Also Consider:

• Ball-Nose Cone Burrs – For blending welds into curves

• Flat-End Cylindrical Burrs – For edge deburring and reaming

• Mounted Points & Felt Polishing Bobs – For final polishing

• Abrasive flap wheels – For post-burr surface blending

🏁 Summary:

Right Lines Dome-End Carbide Burrs are an essential tool for anyone needing precise material removal and finishing in recessed areas, weld corners, or contoured features. Choose from various diameters and shank types to match your application and tool setup.
