From the extremely efficient electro-magnet to the height adjustable frame with reversible feed handles, the new ATRA ACE is more compatible to user needs while offering greater operator safety.
Original OZBROACH cutters drastically shorten drilling time when compared to similar sized conventional twist drills. An optional One-Touch keyed chuck allows the use of up to 12mm twist drills.
Newly developed Over-Load shutdown, magnet open-circuit sensor, and fail-safe restart technology formerly only found on high-end Nitto Kohki automatics is incorporated on the machine to further increase drill output while keeping costs down and safety paramount.
