Comments:There is also FU *ńaḷV- 'get spoiled (skin)' (ND 1594) and PA *ńiĺu 'to polish, scrape' (see ND 1594 *ńaGḷV, where this FU is compared with unsecure Drav. (*nal- 'squeeze') and Arab.); so there may be more roots here. [For Drav. *nal- 'squeeze' cf. Ug. *ńolV 'press'].
References:МССНЯ 347, ОСНЯ 2, 91-92. ND 1582 *ńogüḷV (or *ńogUḷ/ĺV) 'tear asunder, pinch, tatter' (Drav.-Ur. + Mong. noɣula-, noɣura-? + SH *nVgVl-?); ND 1593 *ńuʡl̄V 'pluck, pull out, tear out' (with a great confusion of this root and *nVlV; + Arab.).
