M16x2.00 spiral flute tap for metric threading
The Widia Gtd VTSFT-TC5565 is a high-speed steel tap with black oxide finish designed for cutting M16x2.00 metric threads. It suits machinists and maintenance technicians who need reliable internal threading in through-hole or blind-hole applications.
Replaces worn taps or upgrades from straight-flute
The spiral flute geometry evacuates chips toward the shank, reducing clogging in deeper holes. The jump is worth it when threading blind holes up to 27.7 mm thread length where chip removal becomes critical for thread quality and tool life.
Limited to M16x2.00 thread size and 6H class of fit
The 75 percent thread drill size of 14.00 mm and D7 thread limit define the exact hole preparation required. Right-hand thread direction and three flutes suit standard metric fastening but cannot address left-hand threads or larger diameters.

Questions about this item
What drill size is required for the M16×2.00 thread on this tap?
Use a 14.00 mm drill to produce the recommended 75 percent thread engagement before tapping.
How do you start the cut with a bottoming spiral-flute tap?
Enter the hole straight, apply steady forward pressure, and let the 27.7 mm thread length pull the chips upward without forcing the first turn.
When should this high-speed steel tap be replaced?
Replace it when the flutes show visible wear, the 6H class-of-fit tolerance can no longer be held, or chip evacuation becomes inconsistent.
