Precision Gun Drills

Zonap’s precision gun drills are engineered for small- to medium-diameter deep hole drilling with exceptional straightness and repeatability. Available in:

Solid Carbide and Brazed Gun Drills

• Manufactured from high-grade carbide for rigidity and thermal stability
• Diameters from 3 mm up to 40 mm (customization possible)
• Excellent for hardened steels, alloys, and high-precision components
• Ideal for deep bores requiring minimal deviation and high surface finish

These tools support high-speed drilling with through-coolant delivery and optimized flute geometry for chip evacuation — critical for efficient deep hole cutting.

• Feature brazed carbide tips for a balance of cost and performance
• Suitable for a range of materials and production requirements
• Delivers consistent performance in repetitive drilling
