Deep Hole and Gun Drilling: High-Capacity Precision Drilling Services
At LDC Engineering Ltd, deep hole and gun drilling are at the heart of what they do. These techniques allow for the creation of long, straight, precision bores in a wide range of materials — supporting customers across the UK who need accurate internal holes that standard drilling methods can't achieve. From heater holes to multi-level coolant channels, LDC delivers consistent, high-precision results backed by years of experience.
Gun Drilling Capabilities
Gun drilling is ideal for producing deep holes with small diameters, excellent surface finish, and tight tolerances. LDC Engineering offers gun drilling up to 38mm in diameter, with depths of up to 4 metres depending on the diameter. This service is commonly used in tooling and mould bases, engine components, hydraulic shafts and pins, as well as medical and aerospace parts. Gun drilling is especially beneficial when straightness and internal finish are critical to performance and reliability.
Deep Hole Drilling Capabilities
For larger diameter bores, LDC’s deep hole drilling service can handle holes up to 68mm in diameter, to depths of up to 2 metres. This service is ideal for oil and gas equipment, structural components, heat exchanger parts, and automotive transmission and engine blocks. These larger bores are created with specialist tooling and advanced equipment, ensuring concentricity and precision throughout the full length of the hole.
Why Precision Depth Matters
Whether the hole is 100mm or 4000mm deep, LDC’s team ensures tight tolerances along the full length, smooth bore finishes, and minimum runout and deflection. Their process also includes efficient swarf evacuation and coolant control. These factors are essential in parts that undergo pressure, heat, or high-speed movement, where failure or inaccuracy simply isn’t an option.
