- Radial interlocking connection surface keeps the drill tip rigidly installed, so it stays put under cutting load
- Hole accuracy reaches 8-9 grade, which makes thread base hole machining stable and repeatable
- High-strength drill rod handles different working conditions, adding tool safety during deep hole drilling
- Interchangeable tip design cuts tool costs and simplifies tool management—replace the tip, not the whole drill
- Five diameter multiplier series (1.5xD, 3xD, 5xD, 8xD, 12xD) cover deep hole needs from 12-30mm diameter
