UNISIG Deep-Hole Drilling Machine — Deep Hole

Precision gundrilling and BTA drilling for long, straight, tight-tolerance holes in oilfield and aerospace parts. Long-bore capability — high L/D ratios.

Deep Hole · gundrilling / BTA deep-hole drilling machine

Deep, straight, concentric holes are one of the hardest features to produce on any CNC platform without a purpose-built machine. Most job shops don't have one. Downhole tool bodies, valve stems with long bores, hydraulic cylinders, and any part that needs a straight bore longer than a few diameters routinely gets outsourced — or worse, made poorly on an inadequate setup. UNISIG deep-hole drilling is a genuine capability moat.
