SP-BLF(Coating)

Spiral Fluted Taps, Deep Hole Use, Coated

Specification

The BLF is suitable for deep hole tapping and presents the E Coating following advantages thanks to its geometry with the truncated crests: 1. Elimination of chipping problems at the taps full thread portion. 2. Good chip ejection. 3. Reduction of tapping friction. Recommended Tapping Speeds depending on Materials 4. The internal threads are cut by the chamfer and the 1st full thread. The full thread portion follows the internal threads just cut, and
