  • Driver broke during first project
Size: 1/4-20 Knife Thread Inserts (5)
Worked great for first half, but the driver snapped after about 20 threads and I wound up having to finish driving the rest with a common bolt and nuts anyway

  • great product
Size: 10-32 Knife Thread Inserts (6)
these worked well for a tooling plate i made out of mdf. definitely better to use the installation tool and provided drill as opposed to a screw driver. happy with this product.

  • Skip this kit, just buy the inserts
Size: 10-24 Knife Thread Inserts (6)
The brass knife thread inserts work well, but require care to insert. The EZ-lok DT-3 installation tool will fail sooner or later, depending on wood hardness and torque applied. The DT-3 is suitable for starting the insert into an appropriately drilled hole, but a threaded rod with a nut serves as a better sacrificial driving tool. In hard maple, overdrilling from 25/65 to 13/32 reduced installing torque without apparent reduction in pullout strength. Save yourself some money - skip the installation kit and buy some threaded rod, nuts and inserts. ... show more

  • Great Inserts, but....
Size: 3/8-16 Knife Thread Inserts (5)
These are great inserts overall. I use them for making custom beer tap handles, but need to be aware of the limitations of the installation tool for certain species of wood. If you are working with Walnut the insertion tool will work fine on a heavy enough drill, but if you are working with Cherry or Maple, forget about it. For the super hard woods I use the insertion tool to get maybe the first 2 threads into the piece as it does help keep the insert straight. After that switch to a hardened 1" bolt and a breaker bar to get them flush. No need to use any glue on the insert, they are never backing out once they are in place. ... show more

  • Stripped out threads - driver won't come out without the insert.
Size: 3/8-16 Knife Thread Inserts (5)
I picked this up to make turning Bottle toppers and a few other things easier, the nice insert making it a lot easier to mount on the lathe and install the bottle stoppers. The issue I ran into with this was that the driver worked to install the insert well enough but it also didn't want to release the insert and instead of leaving it behind in the wood as it should, it would pull it out 50% of the time. Maybe a little lube on the threads will make that go easier? The other thing I found was on about 50% of the inserts the threads just rip right off. I'm using the provided drill bit, driver, and inserts. When they work they work well enough but the failure rate is a bit high for my liking. I suggest using some lube on the driver threads to help it release on the way out. I tend to use hardwoods for these projects so maybe the inserts need to have better material so the threads don't peel off? I wouldn't say - don't buy this product - just know what your getting into and try to minimize issues by knowing that this can be an issue in some cases. This is an update after several more uses - The main issue I have is the driver - it gets stuck just about every time and I can back the drill off without pulling out the insert. The Driver needs to be redesigned so it will release from the insert way easier... I've not wasted more money on trashed expensive wood blanks than this tool cost. ... show more

  • Threaded inserts are great
Size: M8-1.25 Knife Thread Inserts (5)
The threaded inserts are phenomenal, however, the installation tool is complete garbage. Save your money, use a good bolt and hardware instead. Both my m6 and m10 install tool snapped off after the insert was too deep to remove. Talk about a headache.
