As with bilabials, English has a limited range of velar consonants. No fricatives, for example. But these are sometimes pronounced in words borrowed into English from languages which do have velar fricatives, e.g. from German, 'Bach'. No uvular consonants in English whatsoever, but they are found in many languages. E.g. both French and some varieties of German have a uvular 'r' sound.
Uvular stops are also common in many languages.
