Reversible Tapping Attachment Hr & Hrf

Salient Features : 'TACO' Patented reversible tapping attachment with robust construction offer following advantagesUsable on every vertical drilling machine or machines with rotating non-reversing spindles.Right or left hand tapping without modification.Complete protection against tap breakage ensured by an ultra-sensitive and smooth operating ball-clutch.Forward and reverse ball drive design transmits rotational power to the tap and disengages smoothly and silently.Axial float ensures smooth tapping and better thread profile.Cushioned drive eliminates the possibility of cross threadings during roughing and finishing taps and ensures gauge perfect thread.A planetary gear reversing mechanism transmits smooth positive reverse to the tap retraction and it retards 75% more faster than it enters.Accurate depth control by means of its accurate neutral mechanism.Batch quantities or mass production of tapping can be achieved accurately by this attachment.Having versatile application in every machine shop, it dispenses with laborious hand tapping and use of expensive machines.Not suitable for radial drilling machines. Collet for HR Model Collet and adjustable left and right nuts to adopt all tap sits, within an attachment's rated capacity. Tap Adaptor for HRF Model The Spindle of the attachment has quick change device. Simple insertion of the tap shank into adaptor is sufficient for chucking.
