Deep hole drilling aluminum can be tricky. When it comes to deep hole drilling the material being used is always a huge factor. Depending on the material, you will need to achieve certain speeds or proper drill bits. Aluminum is usually considered one of the softer materials to drill, but there are some roadblocks you can run into with aluminum.
One of the more highly drilled alloys of aluminum is the 7075 and 6061. One of the major concerns when deep hole drilling aluminum is chip evacuation. Removing the drilled chips are always essential for a successful drill. In addition, chip formation is another consideration.
