Cal-Hawk Tools Nut Splitter Tools - 2-Pc. Set

I had an upper mount for a rear shock on my F-150 that was stripped. Because of the slickness of the shock shaft I couldn’t get a good enough grip with lock pliers, or by drilling a hole in the shock shaft and trying to immobilize it to torque the nut off. Because of the little space I had to work in (2-3 inches clearance) I couldn’t even get a hack saw blade in at it.After a day and a half of fighting with it. I thought, “hey, a nut splitter?”. To shorten the story I settled on purchasing the Cal-Hawk Nut Splitter Tools because of their reasonable price and decent reviews...not super reviews mind you. It was either 5 stars or much lower. As always with Amazon I only needed to wait less than 24 hours and the tools arrived.It took me 15 minutes to get all my tools laid out, including a chisel to remove the split nut, and about 90 seconds to split the nut. As a tip, make sure you have the shoulder of the tool against the bolt or shoulder of whatever you are getting the nut off. Start slow and use a cheater bar/torque wrench and off it comes.The tool bit had no marks. Looks like new. The nut...not so good.End of the story, a great tool at a great price and you get two sizes, going all the way up to just under 1 inch diameter nuts. There’s a “sample” nut in the package to play with and the big tool split it lickity split.Bravo y’all for picking a great tool to sell.

Problem #1: This tool cannot split a 1/2" nut without cutting a deep slit into the nut beforehand with a Dremel or similar power tool. Do not try to split a nut of that size or larger without cutting a slit in it first. You will break the tool.Problem #2: The set screw that stops the wedge from rotating is puny, and didn't last through splitting two 1/2" nuts. Once the set screw gives out, the wedge can just spin freely, which makes it really frustrating to use.Problem #3: The wedge is made of steel that isn't very hard. I had to re-sharpen it with a grinder after every 3rd or 4th nut that I split because the edge just got totally blunted.I ended up being able to use this tool to split almost all of the nuts that attach my truck's bed to the frame. It would've gone more smoothly if there was a better anti-rotation feature than the puny set screw, and if the wedge was harder. So, the job got done, and I couldn't have done it without this tool, but it needs serious improvement.

This will break nuts off, but you have to get the angle just right. Can be a pain if there is a lip on the nut. Used a impact wrench to get the job done faster.

I bought this item for use in my home garage. I was splitting a totally rusted nut on my family sedans ball bearing. The head of tool basically broke off from its body before splitter had reached bolt. I assume tool is more for home improvement use rather than automotive. Splitting through high grade fasteners is probably not what is is designed for. I did see "made in Taiwan" on the package. It did not look like body was made out of hardened steel, more like cast iron. But then again, I am not expert on metals.

Solid. Doesn't require extra wrench to stabilize the splitter.

filled a desperate need in my tool box.worked great. two sizes for different size nuts.Happy purchase!!!

Had a small issue with one. Hopefully I have the problem resolved.

Did a good job splitting the nuts.
