    Finish Boring vs. Reaming | Cutting Tools | .

    It turned out reaming was a better solution because the customer could feed a reamer five times faster than a boring head due to the reamer having multiple flutes. The finish boring head would have been a suitable option if the customer were only machining five holes in a 10-piece job. SMT. Mike Smith is product manager for Seco, Reaming and EPB.

    Back Reaming | 2001-05-31 | National Driller
