E-Z LOK-9000 Thread Insert Drive Tool For Hex Drive Threaded Inserts Installation Drill Install Tool, 1/4-20 Internal Threads

Flange prevents overdriving the insert. Also prevents setting it deep.... Very well made but won't fit standard impact driver since they are 1/4 inch.

Worth purchasing for installing threaded inserts. Saves time and helped drill more precisely.

Overpriced for a simple tool but makes the job super easy. Allowed me to rip through 24 inserts in no time without damaging the inner threads.

This Drive Tool makes it far easier to drive the inserts into the wood being used.

I bought this tool along with some  zinc threaded inserts  for removable bottom panels on the small boxes I build.It works fine for installing the threaded inserts when used in a hand driver, but note that there's no ball detent for using in the small sub-compact drivers that are popular these days (even though there's a ball detent in the product pic). So for a hand driver, it works fine, but for the sub-compacts with a hex chuck it will just pull out. The bit also works great in drills with a traditional check.That said, with some searching online, you can find 4mm hex bits with a ball detent that will work in every situation. McMaster Carr carries a wide variety of them; I grabbed the 2" ball detent bits (mcmaster# 7397A44).Time will tell if they will last as long as the E-Z LOK bit does, but at roughly 1/4 of the price I can't complain.One advantage the E-Z LOK bit has over standard bits is the wide shoulder. When that part touches the wood, the insert is in at the perfect depth, just below the surface of the wood. But again, with the standard bits being so much cheaper, it's very easy to just set them by eye.So the bit performs as advertised, but 1 star off for value.

This made installing 85 threaded fasteners simple and fast.

The drive tool worked as advertised, considered not buying and using an alternative ratchet extension, glad I went with the tool.

Set easy to use and goes in straight.

Works like a dream perfect drives the insert to the perfect level

This tool works like a dream it makes all the difference in using the insert !
