1.2mm 10pcs Diamond Length Point Shape Head Drill Bits

The Diamond Point Shape Head Drill Bits are engineered for high-precision drilling in ultra-hard materials like glass, ceramics, gemstones, stone, and hardened alloys. Featuring a diamond-coated conical tip, these bits deliver clean, accurate holes with minimal chipping, ideal for delicate or industrial applications.

Key Features

• Diamond-Coated Point: Galvanically bonded diamond grit ensures rapid penetration and extended tool life.

• Conical Geometry: Self-centering design for precise hole alignment and reduced wandering.

• Multi-Shank Compatibility: Available with 3mm or 6mm shanks for rotary tools, drill presses, or flexible shafts.

• Heat Resistance: Optimized for high-speed operations up to 15,000 RPM.

Applications

• Lapidary & Jewelry: Drill gemstone beads or crystal pendants.

• Glass & Ceramics: Create holes in stained glass or ceramic tiles.

• Industrial Use: Precision drilling in hardened steel or composite materials.

Technical Specifications

• Shank Sizes: 3mm, 6mm.

• Tip Angles: 60°–120° (customizable).

• Max RPM: 15,000 (use with water cooling).

Why Choose These Bits?

• Precision: Minimizes material splintering for clean edges.

• Durability: Outperforms carbide or silicon carbide bits on hard surfaces.

• Versatility: Suitable for artisan crafts and industrial workflows.

Usage Guidelines

1. Cooling: Use water or coolant to prevent overheating.

2. Speed: Start at low RPM and increase gradually.
