Product Description
The WJ HSSE Oversize Spiral Point Tap M POT is a spiral point tap cut deliberately oversize, used to rescue stripped through-hole threads or to compensate for shrinkage in castings and die castings. Pitch-diameter tolerance is the difference: cut oversize so it can still grip a stripped hole. The substrate is cobalt HSSE rated to HRC40. An oversize thread needs a matching oversize screw - a standard screw will not hold; for blind holes use the oversize spiral flute tap SFT; for standard threads go back to the standard spiral point tap POT. Substrate HSSE cobalt high-speed steel, uncoated, rated to HRC40. It cuts metric M threads, in sizes covering nominal size 3~16mm, pitch 0.5~2, 32 variants. Made in Taiwan. Is an oversize tap the only fix? No - you can tap up a size or fit a thread insert. The advantage here is that hole and screw positions stay unchanged. How do you pick the amount? By the grade marked in the size text, matched to your screws. Typical applications: repairing stripped through-hole threads, compensating hole size in castings, and rescuing threaded holes during maintenance.
