Which of the following hole circles can be used to index for 11 divisions? (A) 21 (C) 33 (B) 27 D) 39 24. A B C D 24. Indexing for a workpiece for a 60 angle would require (C) 6 complete turns and 26 holes on the 39 (A) 6 complete turns hole circle (B) 7 complete turns and 14 holes on the 18. D 7 complete turns
