The GearWrench Ratcheting Wrench Insert bit sets offer the same functionality as a ratchet with a bit socket, but with a lower profile for improved access in tight spaces. The insert bits exceed ASME strength requirements, and fit in 6-point or 12-point wrenches. Available in an 8-pc Metric Hex set (No 81550), an 11-pc Torx Ratcheting set (No 81560) or a 41-pc Master set (No 81602). The 41-pc set includes a blow molded storage case.
