Widia Gtd M7x1 Spiral Flute Tap
This Widia Gtd spiral flute tap cuts M7x1 metric threads in a single pass. The bottoming chamfer reaches full thread depth near the bottom of blind holes. High-speed steel construction with black oxide finish resists wear during repetitive threading tasks in automotive and general machine shops.
Suited for right-hand blind-hole threading
Machinists creating 6H class fit threads in blind holes will find the 17.5 mm thread length and D5 limit appropriate. Builders needing through-hole taps, left-hand threads or larger flute counts for chip evacuation in deep holes should select a different tool geometry.
M7x1 thread size with 6.00 mm drill requirement
The tap requires a precise 6.00 mm drill size to achieve the 75 percent thread engagement specified for the 6H fit. Using an incorrect drill diameter will produce oversized or undersized threads that fail gauge inspection.
Highlights
- M7x1 metric thread fits precise hole sizes
