Widia Gtd M12 Spiral Flute Tap
The Widia Gtd VTSFT-TC5560 is a high-speed steel spiral flute tap designed for creating M12x1.75 metric threads in blind holes. Its bottoming chamfer and black oxide finish suit general-purpose threading tasks in maintenance and production environments. The tool has three flutes despite the two-flute model designation. It is supplied new and ships directly from the distributor.
85.9 mm Overall Length and 23.9 mm Thread Length
The tap measures 85.9 mm overall with a 23.9 mm thread length, providing standard reach for M12 blind-hole applications. The 75 percent thread drill size of 10.30 mm and D6 thread limit targeting a 6H class of fit ensure accurate thread geometry. High-speed steel construction delivers reliable wear resistance in steel and non-ferrous materials. The right-hand thread direction matches conventional fastener requirements.
Upgrade From Worn or Straight-Flute Taps
This tap replaces dull or damaged taps that produce oversize or rough threads in blind holes. The spiral flute geometry evacuates chips toward the shank, reducing breakage risk compared to straight-flute designs in deep holes. The jump is worth it when thread quality in blind holes becomes inconsistent or when tap breakage interrupts workflow. Buyers needing through-hole tapping or larger thread sizes should select a different tool.

Questions about this item
Will the M12×1.75 tap work with a 10.30 mm drill bit I already own?
Yes, the 75 percent thread drill size is 10.30 mm, so your existing bit matches the recommended tapping drill.
How can I verify the tap is cutting correctly once I start threading?
Check that the threads form cleanly to the 6H class of fit over the 23.9 mm thread length and that chips evacuate upward through the three spiral flutes.
Does the package include a handle or only the tap itself?
Only the spiral flute tap is supplied; a tap wrench or T-handle must be purchased separately.
