HTS System • Adjustable Heads with DFT Inserts
The reliable and stable Hertel Tiefbohr System (HTS) adjustable heads with Drill Fix™DFT are designed for drilling system cleaner and deeper holes faster. Depending on your system, inner DFT trigon inserts are available for easy cutting and SPHX outer square inserts guide the drill. A pilot can be used for improved hole accuracy. Inserts are securely positioned in fixed pockets for effortless cutting. The system features helical chip flutes for excellent chip evacuation, even in demanding applications
