Deep Hole Drilling Services

Deep Hole Drilling Services: Precision Solutions for Complex Industrial Applications

Hole Specialists, Inc. is an industry leader in gun drilling, deep hole drilling, pull bore, trepan, and honing services since 1993. At Hole Specialists, Inc., we combine these core capabilities with state-of-the-art equipment, rigorous quality control, and decades of expertise to deliver superior results for our clients. Our comprehensive quality management system ensure consistent excellence across all services.

Deep hole drilling encompasses advanced machining techniques designed for creating holes with extreme depths while maintaining exceptional accuracy and surface finish. Unlike conventional drilling methods, deep hole drilling employs specialized tooling and high-pressure coolant systems to achieve depth-to-diameter ratios of 250:1 or greater. This process is crucial for applications requiring extended-length holes with precise diameter control and superior straightness, commonly used in oil and gas equipment, hydraulic systems, and industrial machinery.

Frequently Asked Questions

What is deep hole drilling?

Deep hole drilling is a specialized machining process for creating holes with depth-to-diameter ratios greater than 10:1. It uses specialized tooling and techniques to maintain accuracy at extreme depths.

What materials can be deep hole drilled?

We can deep hole drill most engineering materials including various grades of steel, stainless steel, aluminum, titanium, nickel alloys, and exotic materials.

What are the advantages of deep hole drilling?

Deep hole drilling provides superior straightness and surface finish at extreme depths. It’s ideal for applications requiring precise, deep holes that cannot be achieved with conventional drilling methods.

How does deep hole drilling maintain accuracy at extreme depths?

We use specialized equipment with guide bushings, high-pressure coolant systems, and precise tool control to maintain accuracy throughout the drilling process.

What tolerances can be achieved with deep hole drilling?

We typically achieve straightness tolerances of 0.002″ per foot of depth and diameter tolerances of ±0.001″ depending on the application and material.
