Deep hole drilling is commonly referred to the most technical challenging drilling application by machining specialists – and for good reason. To begin with, it is important to know what a deep hole is. It is defined as a hole whose depth is more than ten times greater than its diameter. The drills frequently have a length of 30xD or more.
The application presents a number of challenges for the machine, its operator and the tool itself. Having the right coolant pressure and drilling strategy are just as important to a reliable drilling process as having the right special tool. Chip jamming and off-centre holes are two of the most common issues associated with deep hole drilling. Pilot drills with special point angles, high-gloss polished chip spaces and ultra-modern top coatings are available to overcome these issues. They represent the state-of-the-art in solid carbide deep hole drills and are designed to make work easier.
