- Spiral point taps are used to solve the problem of tap breakage in through hole tapping in a wide variety of materials
- The angular flutes in the cutting face propel the chips ahead of the cutting zone, thus reducing loading and clogging in the flutes
- The 1585 style features eccentrically relieved threads with full pitch diameter relief
- These taps are extremely free cutting, resulting in longer tool life
- The use of rigid tapping equipment is highly recommended with this style of tap
- Steam oxide reduces wear and prevents chip welding in harder ferrous materials
