Elimination of chipping problems at the taps full thread portion. 2. Good chip ejection. M26 ～ 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 (for through hole) Spiral Pointed Taps Carbon steel and drives or rotates the tap forward based on the pitch of the threads. low alloy steel Since only half of threads are truncated, the BLF tap does not IS P lose its guiding function, making sure that the tap is able to move 5〜10 forward following the pitch of the threads.
