We have amped up the versatility of a traditional T-handle to give you more of what you need. The t-tool is the perfect addition to your gun cleaning kit. The compact bit driver which is essential for your truck, your tool box, or your emergency kit, ensures that you have all of the most common bits at your reach. This compact T-Tool® functions several different purposes to offer the user versatility: T-handle, rod handle and bit driver. It includes four bits, which are stored in the side of the t-tool. Included bits are: 5/32 inch hex, T20 hex, Phillips #0, Phillips #2. To operate as a T-handle, use in conjunction with an Otis Technology gun cleaning kit. Slide the memory-flex cable through the center groove in the t-tool until the brass end of the cable locks into the groove. To operate as a rod handle, use the 8-32 threaded insert. Attach any 8-32 threaded rod or item into the insert. To operate as a bit driver, insert one of the included bits, or compatible bits you may already own, into the bit holder.
