Manufactured in Taiwan specifically for work on European automobiles, the ten bits are made from the highest grades of steel (compared to competing Chinese kits). We include all 9 known sizes of triple square bit (M4, M5, M6, M8, M10, M12, M14, M16 and M18) PLUS an extra long M10 for VW/Audi inner CV bolt access. To keep them affordable, we use 3 sizes of friction bases. M4 & M5 have a 1/4" drive chrome base. M6 & M8 have a 3/8" drive chrome base. M10 and larger have a 1/2" drive chrome base. The money saved on all those chrome bases allows us to use the highest grades of steel for the bits. The M4, 5, 6 & 8 are S2 tool steel. The M10, 12, & 14 are SAE8660 tool steel. The M16 and 18 are SAE6150 tool steel.
This set is NOT recommended for head bolt removal due to
length and clearance issues. This set is NOT impact tool rated.
