Customer Reviews for VEVOR Universal Vertical Type Pneumatic Tapping Machine Flexible Arm High Strength Machine Arm 1000MM Air Tapping Arm Collet M3-M12

Operates very good up to m10 but struggles after that. However it is dependant on a good air supply! This thing is hard on it and you want a good cfm rating to get the best of it. I've had mine for 2 years now and it gets regular use with no issues other than a defective air lubricator that came with it. (It gushed oil through it and sprayed a mist of oil out the exhaust vents) I simply manully lubricate it periodically Would 100% buy again. Also, get an er16 straight shank and grind the end to match a tap, that way you can use collets to hold tooling other than taps. Handy for deburring and chamfering holes etc

so far, it does what it is expected to do, very pleased with it. nicely built with pre set collets for each thread very easy to change the collets over from size to size.

Lovely piece of kit.well made and well finishedA professional tool without a doubt.

Bonne qualit. un peu de jeu sur l'axe de rotation mais pour 500...tout fonctionne tres bien. moteur pneumatique OK. Livr avec un jeu de douille standard..ideal pour un atelier de mecanique...achat supplementaire de douilles pour M3 et M4 car le ? ne correspondait pas a mes tarauds...utilis pour du M3 debouchant..OKbon couple d'utilisation pour du M6...reste a tester les autres diametres!!!je recommande...

The tapping arm worked great for tapping plenty of holes into6061 aluminium, 4041 steel, and ar500 steel plates.The only problem initially is figuring out what taps actuallyfit in the included collets though. From looking at the Q/A areasupposedly ISO 529 taps work, but the ones I ordered did not, including the metric ones too.Ended up finding imperial tapping collets from ToolLots.Tap sizes that seem to work with the included collets are the 3/16-18 in the m12others seem to be too large or need a little tape to keep in place.4/5 stars since the collets weren't simple to figure out, but saved a heck of lot of time on tapping ~80 holes in AR500 with 3% larger holes than standard in roughly 1 hour vs the 3 days it took for hand taping in a drill press.
