This corer is designed for aeration and hollow coring. The grass roots under your lawn needs air to grow properly, and this tool helps to get air back into compacted soil.
The clever yet simple design that makes this tool unique is the collection box, which catches all the crumpling remnants that eject through the five hollow tines, leaving no mess to clear up. The tines are 100mm long and 12.7mm diameter.
This corer is used by professionals: it's robust, effective, and will last a lifetime.
