1585 Series Spiral Point Taps
Fractional Sizes
Spiral point taps are designed to solve the problem of tap breakage in through-hole applications. 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. Bright finish improves chip flow in soft or non-ferrous materials. The use of rigid tapping equipment is highly recommended with this style of tap.
