This speed reduction attachment drops your TPS drill’s output from 72,000 RPM down to approximately 1,000 RPM, giving you the controlled speed perforator.
This speed reduction attachment drops your TPS drill’s output from 72,000 RPM down to approximately 1,000 RPM, giving you the controlled speed perforator work demands. The 72:1 reduction ratio transforms a high-speed surgical drill into a precision tool for delicate bone work.
Unlike running standard drill attachments at their lowest settings, this chuck delivers consistent torque at the reduced speed. You’ll get better tactile feedback during perforator procedures since the motor isn’t fighting to maintain ultra-low speeds. The upside is more predictable drilling behavior when working near sensitive structures.
Worth noting that this attachment only works with the 5100-10 TPS 100K drill platform. It’s a straightforward swap when you need to switch between high-speed cutting and controlled perforator work.
