Advantages of Deep Hole Drilling
High Cutting Performance
Carbide cutting tools are among the most hardwearing and efficient in the machining industry, enabling tips to cut more quickly and precisely.
Minimum Centre-Line Deviation
Precision is key when drilling deep holes, and gun drilling ensures minimum centre-line deviation. Bores are drilled with near perfect straightness, while deep holes are highly precise even when exacting tolerances are required.
Outstanding Drilling Quality
Whatever the depth of hole being drilled, gun drilling delivers outstanding results in a short duration with only a single pass required.
High Process Reliability
Swarf is an unavoidable by-product of any drilling process. However, in gun drilling the use of high-pressure coolant means the swarf can be continuously removed from the cutting area, reducing machining time and delivering higher quality and repeatability.
Minimal Quantity Lubrication
Gun drilling oils are designed specifically for use in the deep hole drilling of metals that are more difficult to machine. Featuring light viscosity and excellent anti-weld additives, lubricants support tighter tolerances, increased tool life, low oil loss, and superior metal dropout rates when low turnaround filtering times are required.
Application of Deep Hole Drilling
Aerospace: Deep hole drilling is crucial for creating intricate passages and cooling holes in critical aerospace components like turbine shafts, landing gear parts, and hydraulic manifolds. These holes ensure proper functioning and structural integrity.
Automotive: In the automotive industry, deep hole drills are used to create oil galleries and coolant passages in engine blocks, cylinder heads, crankshafts, and transmission components. These passages are essential for maintaining optimal engine performance and longevity.
Medical Devices: The medical device industry relies on deep hole drilling for producing precise holes in surgical instruments, implants, and other medical components. The accuracy and surface finish of these holes are vital for ensuring the functionality and safety of medical devices.
Mold Making: Deep hole drilling is extensively used in the mold-making industry to create cooling channels in molds used for plastic injection molding. These channels help regulate the temperature of the mold during the injection process, resulting in high-quality and dimensionally accurate plastic parts.
Energy: In the oil and gas industry, deep hole drills are used to create precise holes in drilling equipment, pipes, and other components. These holes are crucial for fluid passage and other critical functions in the extraction process.
Defense: The defense industry employs deep hole drilling for manufacturing firearms, artillery barrels, and other military components that require deep, precise holes. The accuracy and surface finish of these holes are vital for weapon performance and reliability.

Deep Hole Drilling Process
Rotating Tool
Typically used for non-symmetrical components, or round parts with off-center holes Cutting speed is determined by tool spindle speed Drill drift can be significant when compared to rotating workpiece, or counter-rotating process
Rotating Workpiece
Typically used for round parts with a deep, on-center hole Cutting speed is determined by part, balanced to allow high rotating speeds Drill drift is reduced compared to rotating tool only
Counter-Rotating Tool and Workpiece
Ideal process for round parts with a deep, on-center hole Cutting speed is determined by a combination of tool and workpiece rotation Provides optimal hole straightness and concentricity
