Detail & Specs
LEFT HAND Reverse Thread / Taps & Dies
Reverse or "left hand" threads are used in applications where the continuous rotation of an assembly would cause a standard right-hand threaded fastener to unscrew while a left-hand fastener would remain securely in place.
TAPS
Metric counterclockwise hand taps are used to repair / chase threading or cut new threads inside of a hole. These taps are good for general purpose applications, use with ferrous (incl. cast iron) and non-ferrous materials, plastic.
The top / starting point of a plug tap has tapered cutting edges for aligning with an existing hole or beginning a new hole. Up to 5 threads are tapered before reaching full height for the remaining length of the tap.
Premium quality, made from HSS high-speed steel, square drive shank.
Also known as second cut straight tap or ground thread intermediate finish tap, plug chamfer tap with straight flute.
DIES
Metric counterclockwise dies are used to chase external threading or cut new external threads for bolts, all thread, studs, etc. These dies are good for general purpose applications, use with ferrous (incl. cast iron) and non-ferrous materials, plastic.
Premium quality, made from HSS high-speed steel, adjustable / split.
Also known as ground thread die, good for hand threading or machine threading.
