Deep-Hole Gun Drilling
Source Deep-Hole Gun Drilling components through FERRASTACK's audited contract manufacturing network in India.
Deep-hole gun drilling creates high aspect-ratio bores for barrels, cylinders, cooling circuits, oil galleries, guide tubes, and cannulated components.
- Typical materials
- It is used on alloy and stainless steels, cast iron, aluminium, titanium, nickel alloys, and other machinable grades.
- Scale & complexity
- Feasibility depends on bore diameter, depth, entry condition, straightness demand, wall section, cross-hole intersections, and component support.
- Tolerance & finishing
- Bore drift, diameter, straightness, internal texture, breakout, and subsequent honing or rifling are assessed from the final application.
- Quality requirements
- Controls can include tool and coolant monitoring, bore gauging, straightness checks, borescope inspection, and cleanliness or flow verification.
- Why source with FERRASTACK
- FERRASTACK matches Indian deep-hole specialists to bore range, component length, material, handling needs, and downstream finishing.
