The flat burr grinder is once the most common commercial coffee grinder in the market . Although it can also be used at home the price that comes out with it because of its more expensive materials usually kept the buyers to purchase it . It is however a very good grinder that fits to make a fine grind espresso . The conical burr as opposed to the flat burr mentioned above is seen as more fit to the house hold use . As the most use home coffee grinders nowadays it falls much into the household financial range not because it is inferior to the flat burr , but simply because it costs less to build one . The conical is great at making vacuum , percolator and French press coffees .
