Put your tomahawk away and instead put the spiral wood splitter into your drill.
Make sure the timber you are about to split is held in place by whatever safe means you can.
Start close to the edge of timber and put some down weight onto your drill so the spiral bites. As it bites, it winds itself down splitting the wood in the process. You'll need to follow the split until the whole section has separated. Then tear off that piece and do it all over again
If your wood splitter gets wedged and it is not splitting the timber simple reverse the drill so the splitter can wind out.
NOTE: Because the shaft of the GroundGrabba Wood Splitter is welded, the shaft and splitter head will not unwind from itself and seperate. But do be careful as the drill spins reverse as the timber may want to spin also.
