Complete Support For Boring Operations For Turning

  • General Feature

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.

  • Characteristics Compatible with a wide variety of tooling

Stop boring / bottom facing / through boring / profiling

  • Minimum machineable diameter: CKB model ø 1 mm–, C-SCLC model ø 5mm–
  • Vibration control boring bar, SumiTurn X Bar
  • Carbide short shank is compatible with turret lathes even without cutting (C15M-STUP model, C20M-STUP model)

E Insert grades and chipbreakers compatible with a wide variety of work materials

  • Steel Shank Type Dramatically improved chatter resistance, especially effective for rough machining of deep holes With Vibration Achieves low cost machining for large diameters/deep holes, shank diameters up to ø32 mm Control Mechanism are in stock
  • High chip evacuation performance, evacuates chips with double chip pocket
  • Types with oil hole are in stock
  • Holders for negative inserts (shank diameter ø25–ø50 mm) are in stock

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!
