Tools & appliances corporation has brought in improved version of its low weight high-speed automatic reversible tapping attachment. Usage of the 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. Specifications: made of alloy steels with all moving parts hardened and ground to precision, this tapping attachment is available in capacities ranging from 2 to 30 mm. An ultra sensitive and smooth operating ball-clutch protects the tap against breakage when the tap is bottomed in a blind hole or core hole is shallow or rap is dull. 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. It is possible to enter the same tapped holes as many times as necessary and still maintain a gauge perfect thread.
