Widia Gtd Spiral Flute Tap M10x1.50
The Widia Gtd VTSFT-TC5559 is a spiral flute tap designed to cut M10x1.50 metric fine threads in a single pass. It suits machinists and maintenance technicians who need accurate internal threads in through holes or blind holes. The bottoming chamfer allows threading close to the bottom of a blind hole. High speed steel construction with black oxide finish provides wear resistance for general purpose threading applications.
Bottoming chamfer frees depth in blind holes
The bottoming style reduces the lead threads so the tap can cut nearer the base of a blind hole without bottoming out. Two flutes provide chip evacuation space while maintaining core strength for the M10x1.50 size. Overall length of 74.7 mm and thread length of 19.1 mm fit standard tap holders and tool posts. A 75 percent thread drill size of 8.50 mm prepares the hole for the D5 thread limit and 6H class of fit.
Upgrades from taper or plug taps for blind work
Switching from a taper or plug chamfer to this bottoming tap gains usable thread depth in blind holes where the hole depth is limited. The three flute design replaces two flute taps when better chip evacuation is needed in ductile materials. The jump is worth it when the application demands full thread depth to the bottom of a blind hole and standard tap holders accommodate the 74.7 mm overall length.

Questions about this item
How does the M10 × 1.50 size and D5 thread limit affect tap life under sustained cutting?
The D5 limit on this M10 × 1.50 tap provides a tighter fit for 6H-class threads, reducing oversize risk during long production runs in steel or stainless.
What heat and chip-load should I expect when running this spiral-flute tap all day in a CNC rig?
High-speed steel with black-oxide coating handles repetitive cuts in ductile metals; the 19.1 mm thread length and three-flute spiral evacuate chips efficiently, keeping temperature stable.
Which drill size and holder do I need before tapping M10 × 1.50 holes with this tool?
Use an 8.50 mm drill for 75 % thread engagement and a standard ER or collet holder that accepts the tap’s shank diameter.
