Widia Gtd Spiral Flute Tap M12x1.50
This Widia Gtd spiral flute tap cuts metric fine threads sized M12 by 1.50 pitch. It is made from high speed steel with a black oxide finish for wear resistance. The bottoming design allows threading close to the bottom of a blind hole. Three flutes provide chip evacuation during the cutting process.
Suited for blind-hole threading in metric fine sizes
Machinists and maintenance technicians creating internal threads in blind holes will find this tap appropriate. The bottoming chamfer and spiral flute geometry are intended for this specific task. Users who require a taper or plug chamfer for through-hole work should select a different tap style. Anyone needing a different thread diameter or pitch must choose another tool.
Straightforward installation in a compatible holder
The tap fits standard tool holders that accept its shank dimensions for machine or hand tapping operations. Correct alignment with the pre-drilled 10.50 mm hole is essential to avoid tap breakage or oversized threads. Using suitable cutting fluid reduces friction and improves thread quality. Applying excessive force or misalignment typically causes premature wear or tool failure.

Questions about this item
What thread size must the pre-drilled hole match for this M12x1.50 tap?
The tap cuts a metric fine M12x1.50 thread; use a 10.50 mm drill for a 75 percent thread depth before tapping.
Will this 3-flute bottoming tap work in a standard right-hand tapping head or holder?
Yes, it has right-hand thread direction and a standard shank that fits common tap holders and wrenches.
How can I confirm the tap is producing the correct 6H class of fit after threading?
Check the finished hole with a 6H go/no-go thread gauge; the go gauge should pass fully while the no-go gauge stops.
