How thick should a beam be
Let's examine the real world fabrication situation and compare Insert Drill Bits with Twist Drill Bits. We'll only look at one example: 13/16 inches (22mm) is the most widely drilled hole.
The Franklin HD145 (3) CNC spindle drill has a 44-inch width. The HD-145 can handle beams up to 775 lbs per foot. High-performance spindles are capable of drilling at speeds up to 2,000 RPM. This rigid design allows for extremely fast feed rates of up to 300 feet per minute. You can order the Franklin HD145 with a variety of material handling packages, ranging from 300 lbs per feet to 750 lbs each foot.
