Porting Tool: 0.888" Spotface Dia, 1/4" Tube OD, Plain, Tube Dash #4 MPN:MS33649-4SA

The porting tool features a 0.888 spotface diameter and a 1/4 tube outer diameter made of plain carbon steel for precision cuts and long service life. Designed with a tubing dash number 4 designation, it provides smooth surface finishes to create clean threads while preventing thread damage. Porting tools like this one serve multiple purposes in engineering and automotive applications, where airflow optimization or fuel flow manipulation is required in engines to increase performance efficiency. This porting tool effectively removes material around the spotface without disturbing the tube walls or deforming existing ports, ensuring accurate measurements for engine component refining processes like intake, exhaust and cylinder head modifications, making it an essential asset within a machinist's or engineer's arsenal.
