If windshields were all you installed you would never need most of these Torx bits, but as technicians we must also install quarter glasses. To install quarter glass it is often necessary to remove seats, interior quarter panels, and even seat belts. Most of these are held in place by a Torx bit. On very large Torx bits you cannot get the leverage with a small ratchet, so we offer the Super Torx Bit Set which has the appropriate size ratchet drive for the bit. Sizes included in the set: T-60 with a 1/2 ratchet drive, T-55, T-50, T-47, T-45, T-40 each with a 3/8 ratchet drive, and T-30, T-27, T-25, T-20, T-15, T-10 each with a 1/4 ratchet drive. Each set comes in a molded, soft plastic container that holds each Torx bit in place. Made in USA.
