ISX15/QSX15 Single Flute Seat Cutter


We have transitioned to the “Single Fluted” Injector Sleeve Seat Cutter for Cummins ISX/QSX15 DOHC Series.

For many years we have used a “Single Fluted” Injector Sleeve Carbide Seat Cutter used for Both: 
250, L-10 & M-11 Copper Series Cylinder Heads and 
M-11 & ISM Stainless Series Cylinder Heads.

  • Proper Spindle Speed (60-85 RPM)
  • Use an adequate Machining Center (Seat & Guide Machine)
  • Use proper tooling lubricity in cutting/machining Carbide to Stainless which is obtained by using our “EA” Lube along with proper downward pressure, a machinist feel, to obtain an acceptable seat finish to depth.

Please consider this field-tested “Single Fluted” cutter, as more machinist are having great usage success in cutting/machining with both Stainless & Copper Injector Sleeves.
