Happybuy Tapping Machine M3-M12 German DIN529 Tap Collets 1000mm Pneumatic Tapping Machine 400rpm per min Vertical Type Air Tapping Machine Perfect

Out of the box, the fittings for the air supply hose from the oiler were missing . The supplier sent hose fittings , but no bushings to attach to oiler, or air supply in. American bushings do not work in Chinese regulator or oiler. Had to wrap several layers of teflon tape around threads , the bushing still bottomed out still leaks air . I will replace regulator and oiler with American units soon. Other than air issues . It taps great.

Can't try it out yet as I need different taps. To help others mine came with DIN noted on the collets and I have the following shank/square requirements to use them. Collet Shank SQUARE DIN 371 SIZES M3 3.5 2.7 M4 4.5 3.4 M5-6 6 4.9 M8 8 6.2 M10 10 8 M12 9 7 Quick update. I’ve used this off and one for a year and a half. No problem finding taps now that I have the right information. I did buy a adjustable chuck to let me quickly insert other taps that I’m not pushing hard example I tap 1/2” plastic and use the adjustable chuck (like a drill) to let me quickly use other taps. I do mostly metric threads and on Amazon I can find the taps I need making sure the the shank is in spec listed above. Then I’m golden. A tube for the water trap is handy and push up to drain. Get pneumatic oil and keep it fairly full. Auto drops doesn’t do well on mine if 1/4” or so level in it. Easy to fill with plastic 8mm bolt to loosen and fill with sight glass. No issues with mine. I do run batches when I run for 3-5 hrs at a time and my Rolair compressor which is 100% duty cycle 20 gal runs none stop. Single stage compressor, used a dewalt wheelbarrow version before from the farm and it works good too. Higher cfm ratings on both.

The tapping arm worked great for tapping plenty of holes into 6061 aluminium, 4041 steel, and ar500 steel plates. The only problem initially is figuring out what taps actually fit in the included collets though. From looking at the Q/A area supposedly 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 m12 others 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.

It works, however most taps do not fit the tapping heads. We are currently using ones from another one that we hav. very disappointed

You cannot find tax to fit this machine I have one tap that would actually fit. No I have a complete full blown machine shop with many taps I also didn’t receive an M6 columns. I am very disappointed. I got this for a gift. I know another people having the same issues with the taps And there’s no information to be found anywhere a waste of time
