Precision deep hole drilling for demanding industries.
DHDS specialises in high-precision deep hole drilling for defence, aviation, mining and commercial sectors. With over two decades of experience, we deliver accurate, reliable drilling solutions for complex materials and demanding specifications.
Precision from ⌀0.7mm to ⌀25mm
Precision micro deep-hole drilling for workpieces up to Ø25 mm in diameter and 600 mm overall length, ideal for producing accurate, small-diameter holes with excellent straightness and surface finish.
Gun drilling
On and off-centre gun drilling from ⌀2mm to ⌀38mm, reaching depths of up to 5000mm depending on diameter. High-pressure coolant and precision tooling maintain straightness and exceptional bore finishes.
Ejector & BTA systems
Our double tube system drilling handles larger diameters and heavier sections while maintaining accuracy, straightness and surface finish.
BTA Counter Rotating
BTA counter-rotating deep-hole drilling for producing hole diameters from Ø20 mm to Ø130 mm, delivering excellent straightness, accuracy and surface finish in large round components.
On & off-centre drilling
We provide angled and offset drilling solutions to suit complex component requirements.
