Hazel produces nuts on wood grownin the previous year, so don't coppice every year or you'll never have nuts and only have pea sticks and never bean poles.
I used to coppice our hazel every 3 to 4 years, depending on the size the regrowth had attained and what I wanted to use it for. Neighbours used to coppice theirs every 7 years; that produced very sturdy poles.
Friends who were thatchers coppiced theirs every 3 - 4 years to produce the spars they needed http://coppice-products.co.uk/product-type/thatching/
