SAE J1926-R (Reamer Pilot) Port Tool

with Coolant Through Holes

A technical drawing of a SAE J1926-R port tool with dimensiooal callouts

The SAE J1926-R Coolant Through Port Tool from Scientific Cutting Tools is engineered to ream the minor thread diameter to final size while maximizing chip evacuation through coolant-through holes. Carbide tipped and precision ground for maximum concentricity, this tool meets SAE J1926/1 and MS16142 requirements. An optional AlTiN+ coating enhances wear resistance and surface finish, making it ideal for demanding ORB (O-Ring Boss) porting applications where accuracy and thermal control are critical.
