When accuracy, alignment, and internal finish matter, precision hole drilling is vital. It’s essential in applications where long, straight bores must meet strict tolerances — from mould tools and engine parts to fluid transfer systems. At LDC Engineering Ltd, precision drilling is delivered through their specialist gun drilling and deep hole drilling capabilities, designed to meet the needs of UK manufacturers across many sectors.
Gun drilling is particularly suited to creating smaller diameter holes with smooth internal finishes and repeatable accuracy. With capacity up to 38mm diameter and depths of up to 4 metres (depending on the specification), LDC can drill fine bores into a wide range of materials — all in-house from their West Yorkshire facility.
Versatile Applications Across Industries
LDC Engineering supports clients working in aerospace, automotive, oil and gas, toolmaking, medical, and more. Their precision hole drilling service is used for:
-
Heater holes in mould and die components
-
Multi-level water circuits for temperature control
-
Pins, shafts, and cylinders requiring long bores
-
Custom components where tight tolerances are critical
The ability to drill into materials like stainless steel, aluminium, copper, bronze, cast iron, resin, and nylon ensures every sector can benefit from LDC’s expertise.
Full-Service Machining Capability
Gun drilling is just one part of the precision offering at LDC Engineering. Their workshop also includes deep hole drilling (up to 68mm diameter to 2m depth), along with CNC milling, turning, radial drilling, and surface grinding. Their large surface grinder (with a table size of 1500mm x 500mm x 350mm) makes it possible to finish large components accurately.
This integrated service means clients can rely on LDC for prototyping, one-off jobs, or full batch production, without needing multiple subcontractors.
