    I've also broken and twisted reamers as well and end up doing it manually on the bridgeport. Speeds and feeds for drilling and reaming stainless steels Introduction Traditionally high speed steel HSS tools have been used for drilling and reaming, but carbide tipped tools are also used for specialised jobs or long production runs.

    During drilling it is essential to maintain the feed to cut through the work hardened layer generated as the metal is cut.
