Automatic Reversible Tapping Attachment

TACO offers a new low weight high-speed automatic reversible tapping attachment. It is suitable for use with standard HSS taps on any drilling machine vertically or horizontally, for right or left hand tapping of blind or through holes. Made of alloy steels with all moving parts hardened and ground to precision. An ultrasensitive and smooth operating ball-clutch protects the tap against breakage when, tap is bottomed in a blind hole or core hole is shallow or tap is dull. Ball-drive forward and reverse is given to the holding spindle of the attachment to obtain significant reduction in friction during tapping operation. A planetary gear-reversing mechanism transmits smooth positive reverse to the tap retraction so there is no possibility of slippage and the retraction is 75% faster than the machine spindle. Axial float ensures smooth tapping and better thread profile. Accurate depth control is by means of its accurate neutral mechanism. Cushioned drive eliminates the possibility of cross threadings during roughing and finishing taps. It is possible to enter the same tapped holes as many times as necessary and still maintain a gauge perfect thread.
