Benefits of Step Drill Bits
Step bits are incredibly useful for one-step drilling operations, but they’re not suitable for all operations.
Some step drills are self-starting, but the larger ones require a pilot hole. Often you can use a smaller step drill bit to bore the pilot hole for a larger one.
Some people hate step bits, but many love them. They seem to be quite popular with professional users who only need to carry a step bit or two rather than several twist bit sizes.
- (relatively) clean holes
- short length for easier maneuverability
- faster drilling
- no need for multiple twist drill bit sizes
