Just fit the new, patented, double turbine 625XDT Series spindles to your Drill-Tap machine magazine for automatic tool changing and increase production. Air Turbine Spindles® Air Supply Adaptor manifold block connects to the machine spindle housing, via the automatic tool change, to supply air at 90 psi (6.2 bar) to the powerful, direct-drive turbine motor.

Increase milling and drilling feed rates resulting in higher productivity with no duty cycle for true 24/7 unattended production – 30,000, 40,000, or 50,000 rpm up to 0.76 hp (0.57 kW).

For automatic loading from the Drill-Tap magazine, install the spindle-mounted manifold block and align the nozzle to the block connector, which supplies the spindle air to a clean, dry 90 psi (6.2 bar) air supply.

For manual loading installation of the spindle, the side NPT adaptor simply connects to an 8mm ID.

The compact double turbine 600X spindle operates at governed 65,000 rpm or 80,000 rpm. Air Turbine Spindles® patented governor increases air flow volume to match cutting load maintaining rated high speed in cut. The 600X’s low air flow requirement facilitates through spindle air supply on any CNC. Now you get the required high SFM for small tools and 6-10x faster cycles. The miniature profile makes programming easy and fits Bumotec and Chiron machines.

The 600X’s constant high speed optimizes your tool performance, reducing breakages on micro tools. Using only 5 cfm / 2.3 liters per second airflow the 600X series minimizes air consumption.

Our direct drive has only 2 moving parts – operating with no heat and zero thermal effects on accuracy. 2 micron, precision is certified assuring ultra precision. For improved micro tool performance and productivity add the 600X to your CNC magazine. All you need is a 90 PSI, 6.2 Bar dry air through your machine spindle.

Drastically Reduce Cycle Times in Finishing Operations
  • Low Profile For Clearance - Easily Fits Bumotec and Chiron Machines
  • Double Turbine Power
  • No Heat. No Duty Cycle. 2 micron accuracy.
  • Through Spindle Air Supply On Any Machine

The 650X series delivers constant high speed with ultra-low vibration and improves accuracy and rigidity. Rigid steel construction in one piece with the tool holder also cuts the height of the unit. With Air Turbine Spindles® patented double turbine’s extra power the 1.4 hp (1.04 kW) motor maintaining stable high speed and torque under load. The 650XHSK-A63 accelerates feed rates and cuts cycle times as a result of its low friction power unit with few moving parts. Rated governed speeds available are 25,000, 30,000 and 40,000 rpm. Plenty of power to speed up your inches cut per minute. High cutting speeds are maintained at the periphery of your end mill or burr using the 650’s unique governed performance to achieve a faster cycle time, a cleaner finished surface, and more production on your CNC. No Duty Cycle.
