  • M14 × 1.5 metric thread for standard fine-pitch holes
  • 2 mm overall length reaches deep or recessed threads
  • Three-flute spiral design clears chips efficiently in blind holes
  • High-speed steel with black oxide resists wear and reduces friction
  • D6 limit and 6H class ensure precise, repeatable fit

M14 × 1.5 spiral-flute tap for metric threads

This high-speed steel tap cuts right-hand metric fine threads sized M14 × 1.5 with three flutes. It is built for machine or hand tapping in general-purpose metalwork where a bottoming chamfer is required. The black oxide finish adds wear resistance during repeated use.

Verify thread size drill diameter and fit class

Confirm the workpiece uses a 12.00 mm drill for the 75 percent thread engagement before starting. Ensure the application calls for a 6H class of fit and a thread length of 25.4 mm within the 91.2 mm overall length.

Black oxide coating reduces galling without extra

The factory-applied black oxide surface treatment lowers friction and resists chip welding on steel and stainless alloys. No additional coatings or bundled cutting fluids are supplied with the tap.

Questions about this item

Does the Widia Gtd VTSFT-TC5564 tap come with a drill bit or handle, or must they be purchased separately?

Only the spiral flute tap is supplied. A 12.00 mm drill bit for the 75 percent thread depth and a suitable tap wrench or holder must be bought separately.

Should I choose the M14x1.5 fine-pitch version or the M14x2.00 coarse version listed in the supplier title?

Choose the M14x1.5 fine-pitch tap when the component specifies a 1.5 mm pitch; the M14x2.00 coarse version is for a 2.00 mm pitch and will not fit a fine-thread hole.

What does the 91.2 mm overall length mean when the tap is used in a machine?

The 91.2 mm overall length determines whether the tap clears the workpiece and fixture; the 25.4 mm thread length is the maximum depth of full-form threads it can cut in one pass.
