Deep Hole Drilling
Custom CNC Deep Hole Drilling Services
Precision deep hole drilling that produces straight, accurate bores with high depth-to-diameter ratios across steel, stainless steel and aluminum for global B2B buyers.
Capabilities
Deep Hole Drilling Capabilities
We combine gun drilling, BTA and peck drilling to produce straight, accurate deep bores with controlled surface finish.
Gun Drilling
Single-lip drilling for straight, accurate small-diameter deep holes.
BTA Drilling
High-productivity drilling for larger-diameter deep holes with excellent straightness.
Peck Drilling
Controlled chip evacuation for deep holes in difficult-to-machine materials.
High Depth-to-Diameter
Deep bores with high depth-to-diameter ratios held straight and accurate.

Typical Applications
Where Deep Hole Drilling Matters
Typical application examples for deep hole drilled parts across common industries.
Hydraulic Components
Accurate deep bores in hydraulic components support fluid flow and pressure integrity.
Mold & Die Cooling
Deep cooling channels in molds and dies improve thermal control and cycle time.
Shafts & Spindles
Straight deep bores in shafts and spindles support lubrication and assembly.
Our Facility

FAQ
Deep Hole Drilling Questions
What depth-to-diameter ratio can you achieve?
We produce deep bores with high depth-to-diameter ratios using gun drilling, BTA or peck drilling depending on the hole size and material. Share your hole dimensions and we will confirm the achievable result.
What hole diameters can you drill?
We drill a range of diameters from small gun-drilled bores to larger BTA holes. Send your diameter and depth for a recommendation.
Which materials can you drill?
We drill steel, stainless steel and aluminum, including difficult-to-machine alloys.
What surface finish can you achieve inside the bore?
We control bore surface finish through drilling method and parameters to match your drawing.
Can you drill prototype parts?
Yes. We drill prototype and low-volume parts so you can validate hole quality before production.
