The mechanics at the Summit Auto Parts Supply company have announced a great advance in the technology of auto-related instruments such as electric hand drills and spanner wrenches. In the past，these have generally been fashioned out of the heavy steel parts and angled at a certain degree, but this new technology enables mechanics to have a flexible-angle tool by which they can extend their arms to what needs repairs longer and control their movements much more. These auto-related tools will weigh less than ever before because they are made from titanium. Most mechanics shower compliment on this improvement. On the other hand, some strongly criticize the additional cost of purchasing instruments made with the new technology.
