I have no idea whether or not this Jake fellow is for real, but what he experiences on the jobsite looks oh-so-familiar…

The video below contains a split screen view of a construction worker (Jake) using rotary hammers to perform the same tasks on different days of the week. On Monday he uses a cord; on Tuesday he goes cordless. Jake is far more productive on Tuesday, and the reasons for that will be obvious to any tradesman who watches what happens.

The video was produced by Hilti and is intended to promote the use of cordless tools for concrete drilling applications, and in a roundabout way, a particular cordless rotary hammer drill. In case you're interested, it's the TE 2-A18. According to the manufacturer, this model is optimized for drilling 3/16” to 3/8” anchor holes or through holes in concrete and masonry. Features include a high-efficiency motor, break-resistant housing, and a built-in LED light. The tool can be used with compact batteries (1.6 Ah) to save weight or with full size batteries (3.3 Ah) for extended runtime. The kit version (tool, two batteries, charger, soft bag, and two 6-inch bits) sells for $399 with 1.6 Ah batteries and $499 with 3.3 Ah batteries.
