KOOTANS Adjustable T-Handle Ratchet Tap Holder Wrench + 5pcs M3 M4 M5 M6 M8 Machine Screw Thread Metric Plug T-shaped Tap, Bothway Hand Screw Tap Set Manual Tapping Tool Kit for Home Use (Long)

Bottle cage bolt rusted and snapped inside of my bike frame, so I needed to drill the hole out and tap new threads. This tool got the job done in a situation I was worried wasn't fixable, so I'm very happy with it. Obviously for $11 it's not the highest quality tool in the world, but it works in tight places, and the ratcheting mechanism is neat as well, I'd never seen a tap with that feature before.

Just what I needed

The tool appears to be well made and suitable for its intended purpose. Since I have not used it yet, I cannot provide a complete review.

Good product

One use, and it broke. To be fair, it actually broke on the third tap, but that third tap was within the same 20 minutes on the same piece of metal. Having said that, though, I was tapping M6x1 into existing M5x1 holes in an aluminum piece by hand--is there anything that should be easier? This kind of quality and longevity is inexcusable. I would not suggest buying this for your worst enemy. I recommend Amazon remove this junk from their inventory.

I only needed to thread one tiny #4-40 set screw into aluminum, so it managed the task.Feels cheaply made, I would not trust this for any serious work.When I was figuring out how to insert the tap, I accidentally disassembled it (b/c no instructions included), and less puzzle-inclined people could have serious trouble if they unscrew it too far.

I needed this for an M6 1.0 bolt hole that holds the headlight in a 1993 Mitsubishi Delica. It worked great for me and the headlight is now fully bolted in. I can't speak to the durability since I used one part one time but it did what I needed and the long handle was awesome for the fitment I needed.

works well for what it was intended
