Product review (5 stars): This product allows me to do overhead work without straining ...
This product allows me to do overhead work without straining my neck and shoulders. Additionally , the Li-Ion batteries have allowed me to de-panel and re-panel the inspection plates of a Cessna 172, a Beechcraft Bonanza, and a Piper Arrow IV on a single charge. Furthermore, the low speed allows safe installation of Stainless Steel and Titanium fasteners without damage and overheating. I've discovered the quality of Hitachi products as a result of the long relationship with John Deere. Hitachi supports Deere with its power tools up to and including Deere's large excavators(made by Hitachi). Hitachi's Li-Ion technology has allowed me to surpass the DeWalt DCF610 12v Drill/Driver by 15%. All things accuate, the DCF develops a much higher torgue, which consumes more power. Each has its own niche.
