Use 「無骨」 for someone (often a man) who is unrefined and rough-hewn; it can carry a favorable sense of rugged simplicity, as in 「無骨な手」 or 「無骨者」. For plain rudeness or vulgarity pick 「粗野」; for poor manners or etiquette pick 「無作法」. 「失礼」 is the everyday word for impoliteness, 「無礼」 a graver slight to superiors, 「不躾」 brusque ill breeding (often 「不躾ながら」). For slapdash work or rough conduct try 「粗雑」 or 「荒っぽい」; 「ごつい」 is physical ruggedness; 「優美」 is the elegant opposite.
