Deep Hole Drilling and Gundrilling Services for Precision Bores

Deep hole drilling generally refers to creating holes with a high depth-to-diameter ratio, often when conventional drilling methods can no longer reliably control straightness, bore quality, chip removal, or heat. Gundrilling is a common deep-hole method that uses specialized tooling and coolant delivery. The appropriate process depends on the required diameter, depth, material, tolerances, finish, and part geometry.

Gundrilling is used to produce long, straight, precise bores in components where internal alignment and surface quality matter. Typical applications include aerospace and defense components, hydraulic parts, tooling, energy equipment, medical devices, shafts, and other engineered metal products. It is particularly useful when a standard twist drill may struggle with deep bores, chip evacuation, or maintaining accuracy through the full depth.

A useful quote request should include a drawing or clear part description, material grade, starting stock dimensions, bore diameter and depth, tolerance requirements, desired surface finish, quantity, and required delivery date. Note any secondary machining, heat treatment, testing, traceability, or certification requirements. Providing the complete specification early helps the team evaluate material availability, processing needs, and the most practical path forward.

Yes. Aero-Vac Alloys & Forge, Inc. supports alloy material sourcing alongside value-added services such as custom saw cutting, machining coordination, heat treatment support, and independent testing. This integrated approach can reduce the number of suppliers a buyer needs to manage. Share the required material specification, dimensions, condition, quantity, and documentation needs so the team can assess the most appropriate sourcing options.

Many engineering alloys can be deep-hole drilled, including alloy steels, stainless steels, tool steels, nickel alloys, titanium, and other materials used in critical applications. Suitability depends on machinability, hardness, cleanliness, bore geometry, and finished-part requirements. Material condition and any heat-treatment sequence should also be considered, since they can affect tooling performance, bore finish, dimensional control, and overall processing strategy.

Yes. Aero-Vac offers independent third-party testing to confirm material conformance before shipment, including destructive and non-destructive methods. Testing should be defined around the applicable material specification and project requirements, such as chemical analysis, mechanical properties, ultrasonic examination, or other requested verification. Identifying documentation and test requirements during quoting helps ensure the correct testing path is coordinated before material ships.

Aero-Vac Alloys & Forge, Inc. handles both small quantities and larger orders. This flexibility can be valuable for prototype development, replacement parts, qualification work, and ongoing production programs. Requirements such as material availability, part size, drilling complexity, certification needs, and delivery timing influence the most suitable approach. Provide expected quantities and future demand where possible to support accurate planning and pricing.

Aero-Vac has experience exporting to points around the globe and supports customers across the United States and worldwide. Shipping arrangements depend on the destination, product dimensions, weight, packaging requirements, export documentation, and requested delivery schedule. For international projects, provide the destination country and any known import or documentation requirements early so logistics and material conformance needs can be reviewed together.
