The BIHUI BU-DMB20 Dry Diamond Milling Bore (20mm, M14 thread) is engineered to deliver clean, accurate results when working with tough surfaces. Whether used by professional tilers or DIY enthusiasts, this tool ensures reliable performance and reduces the risk of cracking or tension around drilled holes.

Key Features

• 20mm medium-grit diamond milling bit for efficient material removal.
• M14 threaded fitting compatible with standard angle grinders.
• Functions: Enlarging, countersinking, shaping, and smoothing drilled holes.
• Applications: Ideal for porcelain, ceramic, granite, and natural stone tiles.
• Performance: Designed to prevent stress fractures and ensure a smooth finish after drilling.

Why It Stands Out

• Precision engineering: Ensures clean, controlled milling without damaging delicate tile surfaces.
• Versatility: Suitable for both professional construction projects and home renovations.
• Durability: Diamond grit provides long-lasting cutting efficiency, even on dense materials.

Typical Use Cases

• Enlarging holes for plumbing or electrical fittings in tiled surfaces.
• Smoothing rough edges after drilling to achieve a professional finish.
• Shaping openings in stone or ceramic for custom installations.
