Buying advice

When selecting a spiral flute tap, consider the material you will thread. For blind holes, spiral flute taps are ideal as they push chips upward. Look for coatings like TiN for general use or TiCN for harder materials. For aluminum, opt for AlTiN or uncoated polished taps. Ensure the tap size matches your thread requirement and check if your application is through-hole or blind-hole specific.
