The Bosch Professional versatile 10-piece set includes ratchet spanners in most common sizes. All spanners can be used for a wide variety of applications as every spanner combines both an open-ended and a ratchet ring spanner in one single product. All of the spanners are perfectly suited to working in tight spaces as the toothless ratchet only requires a backswing angle of 3 degrees. These are manufactured from high-quality chrome vanadium steel with a hardened bi-hexagonal ring, the spanners are robust and long lasting. The 10-piece set includes ratchet spanners in the following common sizes: 8, 10, 12, 13, 14, 15, 16, 17, 18, and 19 mm. This set comes in a practical half-size inlay that is compatible with Boschs L-BOXX Mobility System.
