The SEC-Boring Bar Series is a collection of SEC-Small Diameter Boring Bars, a product we began selling in 1976 which continues to be popular today, steel/carbide shank holders with a highly rigid head design, SumiTurn X Bar which includes a vibration control mechanism, and optimized insert grades and chipbreakers.
Stop boring / bottom facing / through boring / profiling
E Insert grades and chipbreakers compatible with a wide variety of work materials
Assists evacuation of chips New vibration control mechanism X New head design Effective Chattering Killer System X bar cross section Evacuation of Evacuation of long chips short chips
Direction to which vibration generates during cutting
Flattened weight vibrates with opposite phase from the chatter
Strong cross-section High rigidity rib and dramatically reduces chatter!
withstands high cutting forces
