## Questions & Answers

**Q: Can you use these more than once?**
A: Yes, I have used them at least 30-40 times.

**Q: do you think i could split oak logs 2 foot dia with these?**
A: No these are for splitting rocks not wood.  They would just sink in and not do anything.  You need to either get a splitting wedge for wood or a splitting maul.

Something like this:
https://www.amazon.com/Manual-Log-Splitter-Wedge-Diamond/dp/B01N3SXC9W/ref=sr_1_5?crid=1QZ1KADKO3GEU&keywords=wood+splitting+wedges&qid=1650974922&sprefix=wood+splitting+%2Caps%2C270&sr=8-5

Or this which I have and works awesome:
https://www.amazon.com/Fiskars-Core-Maul-Inch-751110-1003/dp/B014M9LQGG/ref=sr_1_5?crid=127EHA9K6FCXK&keywords=splitting+maul&qid=1650974975&sprefix=splitting+maul%2Caps%2C183&sr=8-5

**Q: Has anyone tried these on thicker concrete? I have a piece 3ft x 3ft x 12" thick that I'm hoping to split into smaller sections.**
A: I have not split concrete, but I have easily split granite thicker than 12".  Watch examples on youtube.

**Q: Should I use 5/8 in or 3/4 in carbide drill bits?**
A: Use the drill bit size of the shims (feathers).  5/8 drill bit for 5/8 shims.  You can always enlarge the hole if necessary.   Important - do NOT drill deeper than the length of the shim.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Breaking bolders were easy and fast
*by S***. on August 9, 2025*

Works great on boulders that were to heavy to move. the hard part is drilling holes into the rock, however sweges work great.

### ⭐⭐⭐⭐⭐ Worked well breaking up unreinforced concrete and 3-4 foot diameter granite Bolders
*by D***N on April 19, 2025*

It helps to watch an online video of how to use the wedges and feathers.Get a good 5/8" 2-4 cutter (Star) masonry drill bit to make things go quicker. Do yourself a favor and use at least a SDS Max hammer drill.Space the holes a maximum of 6" apart. The deeper you make the holes the better they will work.Use a single firm tap on each of the wedges in the line of wedges with a 3 pound hammer (bigger is not always better in this case) and give them a chance to work. Work back and forth on the line and listen to the rock break Pounding on a single wedge tends to be a waste of effort.A magnetic pickup tool helps to retrieve any wedges or feathers that fall in the hole.Worked well for me breaking up a 8-12 inch unreinforced concrete slab and some 3-4 foot diameter granite Bolders

### ⭐⭐⭐⭐⭐ Very good quality and work great.
*by M***E on November 14, 2023*

I've split a lot of granite with these and they hold up well. Drill your holes deep and listen to your rock. It will tell you when it's going to break.
