Tip of the Week

Rotary Hammers are an essential tool, when breaking up, building or generally working with concrete. Here are a few uncommon tips and tricks that will help the tool, bit, and operator. Let the weight of the tool do the work for you; pressing the tool with a large amount of force just leads to exhaustion. Routine maintenance prevents early and preventable mechanical failures from occurring; Grease the shank of the bit every time you change it. You can use your rotary hammer as a heavy duty drill by setting it to the “drill only” setting.
